Cardionerds: A Cardiology Podcast

Dr. Roger Blumenthal, Director of the Ciccarone Center for the Prevention of Cardiovascular Disease at Johns Hopkins, discusses guidelines for cardiovascular prevention. They cover the management of hypertension in a 40-year-old woman, emphasizing lifestyle interventions and combination therapy. They also discuss the assessment of risk and antiplatelet therapy for blood pressure management, highlighting the importance of lifestyle changes and a two-drug combination approach.

Dr. Kim Williams, Chief of the Division of Cardiology, discusses the 2021 ESC Cardiovascular Prevention Guidelines. Topics include dietary recommendations for reducing cardiovascular disease risk, ASCVD modifications, sodium restriction and fiber intake, and controversies surrounding saturated fat and vitamin supplementation.

Dr. Allison Bailey, an advanced heart failure and transplant cardiologist, answers a question about cardiovascular prevention guidelines. The podcast covers the use of coronary artery calcium scoring for risk reclassification, guidelines for cardiovascular prevention and risk classification, and promoting healthy lifestyle and risk stratification using CAC score.

This question refers to Sections 3.2 and 3.3 of the 2021 ESC CV Prevention Guidelines. The question is asked by CardioNerds Academy Intern, student Dr. Hirsh Elhence, answered first by Ohio State University Cardiology Fellow Dr. Alli Bigeh, and then by expert faculty Dr. Eugene Yang. Dr. Yang is professor of medicine of the University of Washington where he is medical director of the Eastside Specialty Center and the co-Director of the Cardiovascular Wellness and Prevention Program. Dr. Yang is former Governor of the ACC Washington Chapter and current chair of the ACC Prevention of CVD Section. The CardioNerds Decipher The Guidelines Series for the 2021 ESC CV Prevention Guidelines represents a collaboration with the ACC Prevention of CVD Section, the National Lipid Association, and Preventive Cardiovascular Nurses Association. Question #1 A 48-year-old Pakistani woman with rheumatoid arthritis comes to your clinic asking how she can reduce her risk of ASCVD. Her mother died of an MI at age 45, her father is healthy at age 79. Her calculated 10-year risk based on SCORE2 is 3%. SBP is 120 mmHg, LDL is 120 mg/dL. What is the next best step? A. Order an echocardiogram B. Schedule a follow-up appointment in 1 year C. Discuss initiating a statin D. Repeat lipid panel in 3-5 years  Answer #1 Answer: C. Discuss Initiating a statin The absolute benefit derived from risk factor modification depends on the absolute risk of CVD and the absolute improvements in each risk factor category. Risk factor treatment recommendations are based on categories of CVD risk (“low-to-moderate”, “high”, and “very high”). The cut-off risk levels for these categories are numerically different for various age groups to avoid undertreatment in the young and to avoid overtreatment in the elderly. As age is a major driver of CVD risk, but lifelong risk factor treatment benefit is higher in younger people, the risk thresholds for considering treatment are lower for younger people as per the ESC guidelines. Treatment decisions should be made with shared decision-making valuing patient preference.  Option A is INCORRECT- there is a lack of convincing evidence that echocardiography improves CVD risk reclassification, and it is NOT recommended to improve CV risk prediction. (Class III, LOE B) Option B is INCORRECT- simply doing nothing is not appropriate for this patient with elevated CVD risk.  Option C is CORRECT- This patient has a seemingly low 10-year CVD risk based on SCORE 2 of 3% and her SBP is controlled; however, given her age she is considered as having high CVD risk, therefore treatment should be considered. Stepwise approach involves targeting LDL <100 (class IIa) so initiating a statin would be appropriate. This patient also carries several risk enhancing modifiers including Pakistani ethnicity, family history of premature CVD, and inflammatory comorbidity. All patients should be counseled on smoking cessation, lifestyle modifications, and target SBP <160 mmHg. Option D is INCORRECT- repeating a lipid panel without risk factor modification will not change treatment recommendations for this patient with elevated CVD risk.  Main Takeaway In summary, when a patient <50 years old without established ASCVD has an estimated 10-year risk 2.5 to <7.5% they are considered high CVD risk and risk factor treatment should be considered. Risk modifiers should also be taken into consideration. *Of note- ACC/AHA guidelines recommend the ASCVD risk calculator to estimate 10-year risk and do not restructure CVD risk groups according to age groups. High risk in the ACC/AHA guidelines is considered to be >20%. Guideline Location Table 5 and Figure 5, Page 32513.2.3.4, Page 32533.2.3, Figure 6 page 32523.3, Pages 3258-3259  CardioNerds Decipher the Guidelines - 2021 ESC Prevention SeriesCardioNerds Episode PageCardioNerds AcademyCardionerds Healy Honor RollCardioNerds Journal ClubSubscribe to The Heartbea...

CardioNerds (Amit Goyal and Daniel Ambinder) and guest host, Dr. Priya Kothapalli (UT Austin fellow and CardioNerds Ambassador), join SUNY Downstate cardiology fellows, Dr. Eric Kupferstein and Dr. Gautham Upadhya to discuss a case about a patient who had coronary artery bypass grafting that was complicated by a LIMA grafted to the great cardiac vein. Dr. Alan Feit (Professor of Medicine, SUNY Downstate) provides the E-CPR for this episode. Dr. Moritz Wyler von Ballmoos (Director, robotic cardiac and vascular surgery for Houston Methodist Cardiovascular Surgery Associates) provides a special perspective regarding coronary artery bypass grafting as it relates to this case. Episode introduction with CardioNerds Clinical Trialist Dr. Jana Lovell (Johns Hopkins). Left Internal Mammary Artery (LIMA) to Left Anterior Descending (LAD) artery anastomosis is the cornerstone of Coronary Artery Bypass Graft (CABG) surgery. Anastomosis of the LIMA to the Great Cardiac Vein (GCV) is a known but rare complication of the surgery. Currently there are no clear guidelines in regard to further management. We report a case of a LIMA to GCV anastomosis managed with a drug eluting stent (DES) to the mid LAD after ruling out a significant left to right heart shunt.

The patient determines when the angina is no longer stable angina.The placebo effect of our interventions should not be discounted.LIMA to GCV anastomosis creates a left to right cardiac shunt. A Qp:Qs greater than 1.5 signifies a significant shunt.Increasing the pressure in the coronary sinus may actually be beneficial to the patient.LIMA-LAD is remains the most efficacious and long lasting graft but why not other arterial grafts? Notes - Coronary Artery Bypass Grafting: An Iatrogenic Left to Right Cardiac Shunt Iatrogenic anastomosis of the LIMA to the GCV is a rare but noted complication of CABG surgery. Review of the literature has reported under 40 such cases of arteriovenous fistula formation in the coronary system. Detection of the anastomosis generally stems from recurrent angina which can be attributed to unresolved ischemia or coronary steal syndrome but also can be detected with new heart failure (namely right sided heart failure due to left to right shunting). Diagnosis is usually made with coronary angiography, but CT coronary angiography has also been reported. Due to the rarity of this complication, no clear guidelines are in place directing the management leaving it to the discretion of the various Heart Teams. Evaluating for signs of heart failure and/or ischemia, and measuring the Qp:Qs have been the most common signs directing management. Various options are available for closing the fistula and include coil or balloon embolization, vascular plugs, venous ligation or a covered stent. Redoing the surgery is also an option. Spontaneous closure of the fistula has also been reported. Lastly, if redo surgery is not performed then regardless of fistula closure, coronary intervention for the native diseased artery may be pursued to relieve symptoms.

Show notes - CardioNerds Rounds: Challenging Cases of Cardiovascular Prevention with Dr. Martha Gulati Case #1 Synopsis: A 55-year-old South Asian woman presents to prevention clinic for an evaluation of an elevated LDL-C. Her prior history includes hyperlipidemia, hypertension, obesity, and pre-eclampsia. She was told she had “high cholesterol” a few years prior and would need medication. She started exercising regularly and cut out sweets from her diet. Before clinic, labs showed: Total Cholesterol (mg/dL) of 320, HDL 45, Triglycerides 175, and (directly measured) LCL-C 180. Her Lipoprotein(a) is 90 mg/dL (ULN being ~ 30 mg/dL). Her HbA1C is 5.2% and her 10-year ASCVD Risk (by the Pooled Cohorts Equation) is 5.4%. Her recent CAC score was 110. She prefers not to be on medication and seeks a second opinion. Takeaways from Case #1 As Dr. Gulati notes, in the 2019 ACC/AHA Guideline on the Primary Prevention of Cardiovascular Disease, South Asian ethnicity is considered a “risk enhancing factor.” The pooled cohort equations (PCE) may underestimate risk in South Asians. Furthermore, risk varies within different South Asian populations, with the risk for cardiovascular events seemingly higher in those individuals of Bangladeshi versus Pakistani or Indian origin. There are multiple hypotheses for why this may be the case including cultural aspects, such as diet, physical activity, and tobacco use. A better understanding of these factors could inform targeted preventive measures.In the same 2019 ACC/AHA Guideline on the Primary Prevention of Cardiovascular Disease mentioned above, history of an adverse pregnancy outcome (APO) increases later ASCVD risk (e.g., preeclampsia) and is also included as a “risk-enhancing factor.” Studies have shown that preeclampsia is an independent risk factor for developing early onset coronary artery calcification. Recent data has shown that the risk for developing preeclampsia is not the same across race and ethnicity, with Black women more likely to develop preeclampsia. Black women also had the highest rates of peripartum cardiomyopathy, heart failure, and acute renal failure. After adjustment for socioeconomic factors and co-morbidities, preeclampsia was associated with increased risk of CVD events in all women, the risk was highest among Asian and Pacific Islander women.

CardioNerds (Amit Goyal), Dr. Natalie Stokes (Cardiology Fellow at UPMC and Co-Chair of the Cardionerds Cardio-Ob series), and episode lead Dr. Priya Freaney (Northwestern University cardiology fellow) discuss “The Fourth Trimester” with Dr. Malamo Countouris and Dr. Alisse Hauspurg, from the University of Pittsburgh Departments of Cardiology and Obstetrics and Gynecology, respectively. We discuss the cardiovascular considerations after adverse pregnancy outcomes in the postpartum and long-term follow-up periods. The discussion is focused mainly on hypertensive disorders of pregnancy (HDP), guided by a series of clinical vignettes. We cover a wide range of topics from cardiovascular complications and management considerations in the immediate postpartum period after a HDP, postpartum outpatient follow-up, long term cardiovascular morbidity related to HDP and related preventive strategies, contraceptive considerations for the cardiologist, and interdisciplinary care management pearls for cardiologists working in a cardio-obstetrics team.

Pearls - The Fourth Trimester Blood pressures >160/110 should be treated like a true emergency during pregnancy and the postpartum period, as the cerebrovascular circulation is more sensitive to hypertension, due to hormonal changes related to pregnancy.Women with pre-eclampsia are at higher risk for peripartum cardiomyopathy. Have a low threshold to do a clinical heart failure evaluation (i.e., natriuretic peptides, echocardiogram), and administer diuretics as appropriate to improve volume status and blood pressure.Women with HDP should have their blood pressures monitored closely after discharge, ideally with a home BP monitoring program, as they can have exacerbations of their HTN for up to 2 weeks postpartum.The American Rescue Plan Act of 2021 included a landmark policy to extend postpartum Medicaid coverage up to a year postpartum (from 60 days).Remember to take a reproductive history for every woman you see in cardiology clinic! This can be done in one minute. At a minimum, include obstetric history [number of pregnancies, outcome of each pregnancy, gestational age and weight at delivery, pregnancy complications (HDP, GDM, etc), and delivery method] and menopausal history (age at menarche, age at menopause).The Pooled Cohort Equations may underestimate ASCVD risk for a woman who has had pregnancy complications or premature menopause – consider obtaining a CAC score to aid in risk-stratification in middle-aged women who may have underestimated risk.Low dose aspirin during pregnancy in women who have risk factors for pre-eclampsia reduces the risk of development of HDP by 15-20%. Quotables - The Fourth Trimester “Some of our traditional approaches to caring for women in the postpartum period just aren’t realistic…we need to think about how we can improve care from a policy standpoint to ensure women have access to care and think about how we deliver care.” – Dr. Alisse Hauspurg “Silos are never good. Cardio-obstetrics is a space where you really want to have open communications, be truly collaborative – taking into consideration the expertise of multiple disciplines…because it’s really hard to do it alone.” – Dr. Malamo Countouris Show notes - The Fourth Trimester For more on hypertensive disorders of pregnancy enjoy: Episode #128: Cardio-Obstetrics: Hypertensive Disorders of Pregnancy with Dr. Jennifer LeweyEpisode #66: Case Report: Severe Pre-eclampsia & Cardio-Obstetrics – UPMC Hypertensive Disorders of Pregnancy 1.     What are some of the immediate postpartum cardiovascular risks and complications following a hypertensive disorder of pregnancy (H...

Case Summary - Dyspnea with an LVAD: A Tale of Hypoxia and Hemodynamics A 53-year-old man with an LVAD placed 3 months prior presents with progressive dyspnea since LVAD implant, though it has acutely worsened over the past 2 weeks. Two weeks ago, he had a hemodynamic and echocardiographic ramp study, where the LVAD speed was increased. By increasing the speed, his LV was more adequately decongested, and flow improved. In the Emergency Department, he was hypoxic on room air, and remained so with escalation ultimately with intubation. Even then he remained severely hypoxic requiring cannulation to veno-venous ECMO. Chest imaging was normal, and LVAD parameters were normal without any alarms. An astute clinician noticed that when the patient became hypertensive, his oxygen saturation improved. A subsequent echocardiogram revealed a patent foramen ovale, with right to left shunting. The patient then went to the cath lab, where simultaneous right atrial and left atrial pressures and oxygen pressures were measured, along with trans-esophageal echocardiography, while adjusting LVAD speed. It became evident that right-to-left shunting occurred only when there was high LVAD speed and low peripheral blood pressure. Essentially, faster LVAD speeds (sucking blood from the LV) and low systemic blood pressure (reducing LV afterload) increased right to left shunting by decreasing the left atrial pressure relative to the right atrial pressure. The PFO was closed at that time, drastically improving oxygenation. He was decannulated and extubated the following day. Invasive Hemodynamic Study Unmasks Intracardiac Shunt With Ventricular Assist Device | Circulation: Heart Failure (ahajournals.org) Episode Teaching -Dyspnea with an LVAD: A Tale of Hypoxia and Hemodynamics Pearls PFOs are present in up to 25% of individuals, including those with LVADs.LV unloading, and therefore LA decompression, depends on both LVAD speed and systemic vascular resistance.Blood pressure dependent hypoxia may be suggestive of a right-to-left intracardiac shunt.Hypoxia refractory to mechanical ventilation should raise suspicion for intracardiac shunt.Patients with LVADs can suffer from the same diseases that anyone can. Notes - Dyspnea with an LVAD: A Tale of Hypoxia and Hemodynamics 1. What factors influence LVAD flow? Factors that influence LVAD flow include pump speed, blood pressure, volume status, RV function, cardiac rhythm, and some other variables. The faster the pump is spinning, the more flow you should provide (to an extent). However, if your LV is underfilled, either from systemic hypovolemia or an RV not providing the needed LV preload, then you have no blood to flow! If you have high systemic vascular resistance, then you will have less forward flow,

CardioNerds, Daniel Ambinder and CardioNerds Academy Program Director, Dr. Tommy Das (Cardiology fellow, Cleveland Clinic), Dr. Jacqueline Latina (Structural heart fellow, Johns Hopkins) discuss aortic stenosis and the story of TAVR from both the historical perspective and in terms of future directions with Dr. Jon Resar, Professor of Medicine and Director of the Adult Catheterization Laboratory and Interventional Cardiology at the Johns Hopkins Hospital. This episode is brought to you for Heart Valve Disease Awareness Day. Audio editing by CardioNerds Academy Intern, Shivani Reddy. As many as 11 million Americans have heart valve disease (HVD)—a potentially disabling and deadly disease—yet 3 out of 4 Americans know little to nothing about heart valve disease.

Pearls and Quotes - Aortic Stenosis and the Story of TAVR In the previous century, patients with severe aortic stenosis who were treated “medically” had 50% mortality over 2 years after developing symptoms. Balloon aortic valvuloplasty was initially touted as extremely “efficacious” for aortic stenosis but follow-up studies showed that the improvement in symptoms were not durable, and long-term prognosis was dismal. The PARTNER Trial started enrolling in 2007 in extreme risk patients – patients who were not surgical candidates. In 2010, the PARTNER trial was published and TAVR blew away the “standard of care” in inoperable patients at the time, cutting outcomes in half (composite of death and repeat hospitalization). The PARTNER trial studied balloon expandable intra-annular valve implantation. The CoreValve trial studied self-expanding supra-annular valve implantation and was published in 2014. The “Heart Team” approach entails collaborative decision making between cardiologists and cardiac surgeons to personalize management for patients. Both intra-annular and supra-annular valves show non-inferior outcomes to surgery in intermediate and low risk patients. Revascularization prior to TAVR is an evolving arena; the trend has been interventionalists performing fewer PCIs prior to TAVR given the benefit is not clear if angina is not a prominent symptom. Show notes - Aortic Stenosis and the Story of TAVR (TAVR/TAVI are using interchangeably) CardioNerds Aortic Stenosis, updated 1.20.21 1. In the 1990s, patients with severe aortic stenosis (AS) who were deemed to be at high surgical risk would weigh the risks of surgery and prolonged recovery. Balloon Aortic Valvuloplasty (BAV) was first performed by Dr. Alain Cribier in 1986. The technique was based on the foundation of pulmonary valvuloplasty performed initially in 1982 by Drs. Jean Kan and Bob White, and mitral valvuloplasty in 1984. BAV was initially touted as an efficacious cure for aortic stenosis, but unfortunately it had a high restenosis rate as well as high risks for stroke and vascular complications (no closure devices at that time) with an overall poor long-term prognosis. Balloon aortic valvuloplasty was primarily used for decompensated Class IV heart failure in non-surgical candidates. 2. Transcatheter aortic valve replacement (TAVR/TAVI) was developed and first performed in human in 2002.(1) This was performed by Dr. Alain Cribier in France in 2002, initially by trans-septal approach and then by retroaortic approach. Here is a representative diagram of the procedure. Figure: Transcatheter Aortic-Valve Replacement. The transcatheter valve is positioned at the level of the native aortic valve during the final step of valve replacement, when the balloon is inflated within the native valve during a brief period of rapid ven...
