Contributor: Travis Barlock MD Educational Pearls: Three categories of pressors: inopressors, pure vasoconstrictors, and inodilators Inopressors: Epinephrine - nonselective beta- and alpha-adrenergic agonism, leading to increased cardiac contractility, chronotropy (increased heart rate), and peripheral vasoconstriction. Dose 0.1mcg/kg/min. Levophed (norepinephrine) - more vasoconstriction peripherally than inotropy; useful in most cases of shock. Dose 0.1mcg/kg/min. Peripheral vasoconstrictors: Phenylephrine - pure alpha agonist; useful in atrial fibrillation because it avoids cardiac beta receptor activation and also in post-intubation hypotension to counteract the RSI medications. Start at 1mcg/kg/min and increase as needed. Vasopressin - No effect on cardiac contractility. Fixed dose of 0.4 units/min. Inodilators are useful in cardiogenic shock but often not started in the ED since patients mostly have undifferentiated shock Dobutamine - start at 2.5mcg/kg/min. Milrinone - 0.125mcg/kg/min.

Show Notes & Take Home Pearls In response to ischemia the myocardium can dynamically change along a spectrum from myocardial stunning to myocardial hibernation to myocardial necrosis. The goals of viability testing are to identify patients who may benefit from revascularization as hibernating or stunned myocardium are potentially reversible causes of LV dysfunction. There are numerous imaging modalities available for the evaluation of myocardial viability. The broad range of ways in which myocardial viability is assessed speaks to the complexity of the disease spectrum and the difficulty in creating a unifying definition of viability to assess in clinical trials. Five Take Home Pearls 1. In response to an acute episode of ischemia with subsequent reperfusion, the myocardium can be exposed to a large flux of oxygen free radicals or calcium overload that affects the cellular membrane and contractile apparatus. This phenotypically results in decreased contractility of the affected region of myocardium that can persist for weeks, labeled myocardial stunning 2. Repeated episodes of myocardial stunning or chronic low myocardial blood flow can lead to cellular changes such as resorption of the contractile apparatus in order to decrease oxygen demand and allow the myocardial cells to survive. Phenotypically, this might appear as regions of hypokinesis or akinesis at rest with a fixed perfusion defect on myocardial perfusion imaging. This is typically considered hibernating myocardium. 3. The goal of myocardial viability testing is to be able to differentiate between stunned, hibernating and necrosed myocardium. In patients with known epicardial coronary disease, this differentiation allows us to identify who may benefit from revascularization with improved LV systolic function and overall survival. 4. There are several imaging modalities that can be used in the assessment of myocardial viability. The most sensitive modalities are FDG-PET and CMR. The addition of Dobutamine or first pass perfusion with Gadolinium additionally increases the specificity of CMR. These modalities are more expensive and not as widely available. 5. The dynamic nature of the myocardial hibernation and the lack of a unifying definition/phenotypic expression of myocardial hibernation and viability have made it difficult for clinical trials to show that re-establishing myocardial blood flow to hibernating myocardium is beneficial. As Dr. Jaber stated in the episode in his spin on the classic opening phrase from Leo Tolstoy’s masterpiece, Anna Karenina, “All normal hearts are normal in the same way, and all abnormal hearts are abnormal in different ways.” 6. The PARR-2 trial was one of the few randomized, controlled trials of patients with LV systolic dysfunction and coronary artery disease who were randomized to either FDG-PET guided management or standard care with respect to whether to pursue revascularization. Overall,
In this 5 minute bit we discuss Phenylephrine, Angiotensin II, Dobutamine and Milrinone. Please see attached evidence related to our topic:*Just to clarify, dobutamine and milrinone can both be used for right ventricular systolic failure but there is some evidence that milrinone may provide better pulmonary vascular afterload reduction than dobutamine. NO MILRINONE IN RENAL FAILURE. MILRINONE IS LONG ACTING. *Just to clarify, Angiotensin II data was not solely tested against placebo. The actual randomized trial had both groups on high dose norepinephrine and one group had placebo as a second agent and the other group had angiotensin II as a second agent. The point of the trial was to demonstrate Angiotensin II efficacy in a patient that was failing high dose norepinephrine alone (or equivalent dose of another vasopressor). So the trial was not really Angiotensin II against just placebo as both groups were also on high dose catecholamine.https://ccforum.biomedcentral.com/articles/10.1186/s13054-014-0534-9https://www.nejm.org/doi/full/10.1056/NEJMoa1704154https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5764562/https://www.ncbi.nlm.nih.gov/books/NBK470431/https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4691094/https://www.escardio.org/Journals/E-Journal-of-Cardiology-Practice/Volume-14/Treatment-of-right-heart-failure-is-there-a-solution-to-the-problem

In this podcast Ty Harrison, a Physician Assistant with the Minneapolis Heart Institute at Ridgeview Heart Center, addresses which type of stress test for chest pain is correct - why and for whom. Ty will also discuss the issue of assigning the wrong test, and that it is largely multi factorial, secondary to associated risk factors. Objectives: Upon completion of this podcast, participants should be able to: Describe how various stress tests are employed. Select which provocative test(s) should be ordered for specific cohorts of patients. Recite the contraindications for stress testing. Identify when a CT coronary angiogram or CMR should be considered, and on which patient subtype(s). CME credit is only offered to Ridgeview Providers for this podcast activity. Complete and submit the online evaluation form, after viewing the activity. Upon successful completion of the evaluation, you will be e-mailed a certificate of completion within 2 weeks.

SHOW NOTES: Before you send a patient over for a stress test, get a baseline EKG. Does the patient have a LBBB? If so, then is the EKG really not interpretable? If the patient has a history of previous MI, or old Q waves via EKG a stress echo is not the appropriate test; as the patient will likely have wall motion abnormalities. The basics of adenosine testing is there are adenosine receptors on the vascular smooth muscle of cardiac vessels which causes healthy arteries to dilate and those vessels that are unhealthy will not dilate creating a perfusion mismatch. The nuclear portion of the stress test is where the radioisotope is given with the adenosine, which is taken up by healthy myocardium. If area has diminished perfusion, this will create a mismatch. Dead tissue will not take up isotope - indicative of a previous infarct. The stress portion of the nuclear test will be to assess for a perfusion mismatch to evaluate for signs of ischemia. You want to compare rest vs. stress images. Lexiscan is an A2A agonist. Advantages do not require pharmacy, single injection, short acting. Lexiscan is the stress portion of the nuclear testing. By the way, the radionuclear isotope is about 10 mSv or equivalent to about 200 chest x-rays. Optimal patient for a Lexiscan is someone who cannot exercise, once again LBBB, paced, those who can walk on a treadmill. Specificity and sensitivity: 90% for Lexiscan, if selected correctly. Cons to Lexiscan are: cost, hospital based, radiation exposure, pregnancy. Pearl: things that buy you an angio on treadmill stress testing are EKG changes, redevelopment of chest sxs, image changes. 2 of those 3 criteria moves us to angio. CHAPTER 2 SUMMARY: The 2-main echos we are concerned with are stress echo, and Dobutamine or chemical echo. Unfortunately, the stress echo is not as sensitive as a nuclear test. The pros of a stress echo: cost, no radiation. The echo process: patient will initially have a baseline-resting echo to look at the EF, and for wall motion abnormalities. Important to point out that this is not a valvular study. Although if Aortic Stenosis is visualized, this generally is a contraindication to stress echo. Sensitivity and specificity: around 85%, not bad. For the stress portion of the test, you are shooting for about 85% of the patient maximum predicted heart rate. Unfortunately, if obese - a nuclear study is a 2-day test due to large amount of radiation required for the studies. An additional contraindication for stress echo would be morbid obesity, COPD, previous cardiac insult with wall motion abnormalities, LBBB, reduced EF. Dobutamine Echos have limited utility. They take a long time to perform. It makes people feel crummy. Physicians usually have to be present. Once caveat would be for the chronically wheezing asthmatic with bronchospasms or history of status asthmatics. Dobutamine is a B1 and B2 agonist, which will help with asthmatic sxs. Dobutamine has inotropic properties and less chronotropic activity, which can occasionally require atropine to increase HR. Dobutamine has limited utility. Treadmill stress testing is used to "rule out" disease. Stress echos are generally considered the appropriate test for women. Caffeine is an adenosine analog and can affect Lexiscan results. Beta-blockers are typically held for about 36-hours. CHAPTER 3 SUMMARY: A treadmill stress test Bruce protocol is performed in 3-minute increments. Starts at a 10% grade, with a pace 1.8 miles per hour. Goal standard is about 10-minutes. Bruce protocol goes to 21- minutes. Predictive value of a significant coronary event if the patient meets the goals of a Bruce protocol is extremely low. Buzz words that make you stop the treadmill test are pretty self-explanatory, include: reproduced chest pain sxs, drop in BP, arrhythmias, EKG changes. The negative predictive value of a neg CT coronary angiogram - in upper 90% range. Elevated calcium scores can limit the efficacy of the CT coronary angio making it difficult to accurately interpret the test. Stress test is for revealing sxs. Stress tests are not for modifying outcomes. If the patient can do 4 METS, usually you can clear them for surgery. Stress test should be a rule-out test. CTA FFR is Fractional Flow Reserve - is an assessment of flow across a coronary lesion. In addition, it tends to take the reader out of the equation.

Join Drs. Trigonis and Murray from the EMGuideWire team as they discuss use and selection of Vasopressors in the ED.
I've known Tiffany for quite a long time now and she truly is like a sister to me. I was so excited to have her on the show, but I've never once worked with her. Despite this, she is such a wonderful person that if I ever was to be sick, injured, or my family needed care I would be so fortunate if she was the nurse. She has been caring for people her entire life, even when not her responsibility. I hope you feel as inspired as I am after listening to her. As we discussed here is a wonderful Florence Nightingale quote: The most important practical lesson that can be given to nurses is to teach them what to observe, how to observe, what symptoms indicate improvement, what the reverse, which are of importance, which are of none, which are the evidence of neglect, and of what kind of neglect. Thank you Tiffany!

Dr Paul Wang: Welcome to the monthly podcast, On The Beat for Circulation: Arrhythmia and Electrophysiology. I'm Dr Paul Wang, editor-in-chief, with some of the key highlights from this month's issue. In our first paper, Ruairidh Martin and associates used ultra-high-density mapping to access the ventricular tachycardia circuit dependent upon re-entry, with scar regions in 36 tachycardias in 31 patients. The author has found that 11 of the ventricular tachycardia circuits and isthmuses were single-loop, and 25 were double-loop. Three had two entrances, five had two exits, and fifteen had dead-end activation. Isthmuses were defined by barriers which included anatomical obstacles, lines of block, and slow conduction in 27 out of 36 isthmuses. The barrier to conduction in isthmus appeared to be partially functional in 75% of circuits. Isthmus voltage is often higher in ventricular tachycardia than in sinus or paced rhythms. The authors found that conduction velocity in the VT isthmus slowed at the isthmus entrances and exits when compared with mid-isthmus. The mean conduction velocity was 0.08 meters per second in entrance zones, 0.29 meters per second in isthmus regions, p < 0.0001, and 0.11 meters per second in exit regions. P = 0.002. In our next paper Daniel Duprez and associates found that plasma collagen biomarkers, particularly at elevated levels, were associated with excess risk of atrial fibrillation. In a stratified sample of the Multi-Ethnic Study of Atherosclerosis (MESA), initially age 45 to 84 years, the authors examined in 3,071 participants plasma Procollagen Type III N-Terminal Propeptide, also known as P3NP, which reflects collagen synthesis in degradation in Collagen Type I Carboxy-Terminal Telopeptide, also known as ICTP, which reflects collagen degradation at baseline. The authors aimed to determine if the levels of these biomarkers were associated with incident atrial fibrillation in participants initially free of overt cardiovascular disease. Incident atrial fibrillation in ten-year follow-up was based on a hospital ICD code for atrial fibrillation or atrial flutter, in or outpatient Medicare claims, or ECG ten years after baseline. The authors found that baseline levels of these markers were positively related, both p < 0.0001 to incident atrial fibrillation in a model adjusting for age, race, ethnicity, and sex. These findings were attenuated but remain statistically significant after further adjustment for systolic blood pressure, height, body mass index, smoking, and renal function. In our next paper, Ahmet Adiyaman and associates conducted a randomized controlled trial comparing the safety and efficacy of minimally invasive thoracoscopic pulmonary vein isolation with left atrial appendage ligation versus percutaneous catheter ablation pulmonary vein isolation. In 52 patients with symptomatic paroxysmal or early persistent atrial fibrillation, paroxysmal atrial fibrillation was present in 74% of patients. The authors found that percutaneous pulmonary vein isolation with a 56% single procedure arrhythmia-free survival at two years was not inferior to minimally invasive thoracoscopic pulmonary vein isolation with left atrial appendage ligation, which had a 29% arrhythmia freedom, p = 0.059. Procedure-related major adverse events occurred in 21% of patients undergoing minimally invasive thoracoscopic pulmonary vein isolation, compared to none undergoing percutaneous catheter ablation with p = 0.029. In the next paper, Richard Ang and associates examined whether the glucagon-like peptide-1 receptor agonist exendin 4 has an effect on ventricular action potential duration in susceptibility to ventricular arrhythmia in the rat heart in vivo and ex vivo. Ventricular monophasic action potentials recorded in anesthetized rats in vivo in isolated profused rat hearts in sinus rhythm and/or ventricular pacing. In vivo systemic administration of exendin 4 increased heart rate and this effect was abolished by beta adrenoceptor blockade. Despite causing sympathetic activation, exendin 4 increased axon potential duration at 90% repolarization, APD90, during ventricular pacing by 7% and reversed the effect of beta adrenoceptor agonist Dobutamine on APD90. In isolated profused hearts, 3 nanomolar exendin 4 increased APD90 by 14% with no effect on heart rate. Exendin 4 also reduced ventricular arrhythmia inducibility in conditions of beta adrenoceptor stimulation with Isoproterenol. Exendin 4 effects on action potential duration in ventricular arrhythmia susceptibility were prevented in conditions of muscarinic receptor blockade or inhibition of nitric oxide synthase. The authors concluded that glucagon-like peptide-1 receptor activation effectively reverses the effects of beta adrenoceptor stimulation on cardiac ventricular excitability and reduces ventricular arrhythmic potential. The effect of glucagon-like peptide-1 receptor activation on the ventricular myocardium is indirect, mediated by acetylcholine and nitric oxide, and, therefore, might be explained by stimulation of cardiac parasympathetic neurons. In our next paper, Michael Barkagan and associates examined the role of modulating baseline impedance on ablation lesion dimension. Radiofrequency ablation was performed using an irrigated catheter at a fixed power setting of 30 watts 20 seconds and a multi-step impedance load from 100 to 210Ω ex vivo in 20 swine hearts and in vivo in the right atrium and in thigh preparations. Ablation was performed using similar power settings at three baseline impedances: low, 90 to 130Ω; intermediate, 131 to 180Ω; and high, 181 to 224Ω. The relationship between baseline impedance, current, and lesion dimensions were examined. Baseline impedance had a strong negative correlation with current squared for all of these experimental models with R either -0.93 or -0.94. Lesion dimensions at similar power setting were directly related to current squared with R = 0.853 for width and R = 0.814 for depth. In thigh muscle lesion depth was greatest at low impedance, 8.2 millimeters, compared to 6.5 millimeters and intermediate impedance and 4.2 millimeters at high impedance, p < 0.0001. In right atrial lines, low baseline impedance resulted in wider lines, 7.2 millimeters, relative to intermediate 5.8 millimeters and high impedance, 4.7 millimeters, p < 0.0001. In the next study, Virginie Dubes and David Benoist and associates examined the origin of ventricular arrhythmias in animal model of repair of tetralogy of Fallot. They studied six piglets undergoing tetralogy of Fallot repair-like surgery compared to five sham-operated piglets. Twenty-three weeks post-surgery, the authors found that right ventricular dysfunction was present, while left ventricular function was preserved in tetralogy of Fallot pigs. Optical mapping showed longer action potential duration on the tetralogy of Fallot left ventricular epicardial and endocardium. Epicardial conduction velocity was significantly reduced in the longitudinal direction but not the transverse direction in tetralogy of Fallot ventricles compared to sham. Elevated collagen content was found in left ventricular basal and apical sections from the tetralogy of Fallot pigs. The tetralogy of Fallot left ventricles had a lower threshold for arrhythmia induction using incremental pacing protocols. In our next study, Meera Varshneya and associates sought to understand the individual roles of slow and rapid delayed rectifier potassium currents, IKS and IKR, and quantify how effectively each stabilize the actions potential, protecting cells against arrhythmias across multiple species. The authors compared ten mathematical models describing ventricular myocytes from human, rabbit, canine, and guinea pig. They examined variability within heterogeneous cell population, tested the susceptibility of cells to a pro-rhythmic behavior, and studied how IKS and IKR responded to changes in the action potential. They found, one, models of higher baseline IKS exhibited less cell-to-cell variability in action potential duration; two, models with higher baseline IKS were less susceptible to early afterdepolarizations induced by depolarizing perturbations; three, as action potential durations lengthened, IKS increases more profoundly than IKR, thereby providing negative feedback that resists excessive action potential duration prolongation; and four, the increase in IKS that occurs during β-Adrenergic stimulation is critical for protecting cardiac myocytes from early afterdepolarizations under these conditions. The authors concluded that slow, delayed rectifier current is uniformly protected across a variety of cell types, suggesting that IKS enhancement could be potentially anti-arrhythmic. In our final paper, Piotr Podziemski and Stef Zeemering and associates performed a direct one-to-one comparison between phase and activation time mapping in high-density epicardial direct contact mapping files of human atrial fibrillation. The authors examined 38 unipolar electrum files of ten seconds duration recorded in 20 patients with atrial fibrillation using a 16 x 16 electrode array placed on the epicardial surface of the left atrial posterior wall or right atrial free wall. Using sinusoidal recomposition and Hilbert Transform, 138 phase singularities were detected, with 104 out of 138 phase singularities detected within on electro distance, 1.5 millimeters, from a line of conduction block between non-rotating wave fronts determined by activation mapping. Only 18 rotating wave fronts were detected out of 8,219 detected waves based on wave mapping. Fourteen out of these 18 cases were detected as phase singularities in phase mapping. Phase analysis of filter electrograms produced by simulated wave fronts separated by conduction block also identified phase singularities on the line of conduction block. The authors found that phase singularities identified by phase analysis of filter epicardial electrograms colocalized with conduction block lines identified by activation mapping. The authors concluded that detection of phase singularity using phase analysis has a low specificity for identifying rotating wave fronts using activation mapping of human atrial fibrillation. That's it for this month. We hope that you'll find the journal to be the go-to place for everyone interested in the field. See you next time.
In non-cardiac ICU patients, the two major causes of acute myocardial dysfunction are sepsis-related cardiac depression (SRCD) and stress-related cardiomyopathy, the most common cause being the former. The main mechanisms responsible for SRCD include release of cardiac-depressant substances such as pro-inflammatory cytokines, hyporesponsiveness of beta-adrenergic receptors, decreased sensitivity of the myofilament to Ca++, and excessive production of perioxynitrite. Echocardiography is the best method to diagnose SRCD. If a cut-off value of 45% left ventricular ejection fraction is used to define SRCD, the occurrence of SRCD is 60% in septic shock patients (40% on the day of admission and in 20% the two following days). Recent advances in ultrasonography such as speckle-tracking (measuring the longitudinal systolic strain) may allow detecting cardiac abnormalities that are not detected by conventional echocardiography. Even when the SRCD is diagnosed, an important issue is to decide to treat it since left ventricular dilatation is an adaptive mechanism associated with a good outcome. The Surviving Sepsis Campaign suggests using dobutamine in patients who show evidence of persistent hypoperfusion despite adequate fluid loading and the use of vasopressor agents. In our opinion, it is more logical to give an inotrope when the shock state persists in the presence of: 1) proven SRCD with echocardiography and, 2) either low (mixed or central) venous blood oxygen saturation or increased veno-arterial carbon dioxide pressure gradient. Dobutamine is still recommended as the first-choice inotropic agent. Levosimendan is considered an alternative as it can restore the sensitivity of the cardiomyocyte myofilament to Ca++. Early administration of norepinephrine can not only increase blood pressure through an alpha1-adrenergic effect but also improve cardiac contractility through a beta1-adrenergic effect and/or an increase in the diastolic arterial pressure (i.e. the perfusion pressure of the left ventricle).

For the 30 years, clinical understanding of haemodynamic resuscitation has been based on physiological paradigms that focus on convective oxygen delivery. Most of these emphasise the role of cardiac output, haemoglobin and recommend interventions using synthetic agents such as dobutamine, synthetic colloids and blood transfusions. Markedly influenced by industry, these interventions and strategies hijacked critical thinking creating a belief in the utiliity of attaining short-term physiological surrogates for resuscitation that have little relevance in improving patient-centred outcomes. This 'physiological fallacy' has been demonstrated in high-quality RCTs of fluids, goal-directed therapy and catecholamines, that paradoxically inform the interpretation of new insights in the physiological basis of health and disease.
