“The Jackson heart study” (conducted at the dept. of cardiovascular medicine at the Mayo Clinic), recently published in the Journal of the American Heart Association has revealed some interesting findings on the association between religiosity / spirituality and cardiovascular health in African American Christians. They were also found to be more likely to adhere to the “AHA’s Life’s Simple 7” practices to maintain good cardiovascular health. LS7 consists of completely cigarette smoking, maintaining an acceptable body weight, good control of blood sugars, good control of blood pressure, good control of cholesterol, atleast 150 minutes of moderate intensity physical inactivity per week, and a heart friendly diet. More research is needed to determine if these beneficial cardiovascular effects also applies to other ethnic groups and other religions

In a recently published landmark study by the European Society of Cardiology on hypertension (high blood pressure) in childhood, the authors concluded that 9 out of 10 children with high blood pressure were physically inactive, had excess salt and excess sugar in their diet. None of these risk factors need medications and can be corrected by just lifestyle modifications alone!

150 minutes may not be quiet enough! Needs to be doubled or quadrupled for maximum benefits! The recommended duration of physical activity for cardiac health by the American Heart Association is 150 minutes of moderate intensity physical activity per week (30 min a day, 5 days a week). This has been the recommendation for many years until recently. According to new research published in the flagship journal of the American Heart Association “Circulation”, though 150 minutes does offer some cardiovascular protection, the maximum benefits from exercise accrue when that number is doubled to 300 minutes or better quadrupled to 600 minutes of moderate-intensity physical activity per week. For easy quantification the AHA has graded the intensity of exercise by the “talk test”. Moderate exercise / activity is defined as the level of intensity that allows a person to talk but not sing during the exercise. Vigorous physical activity is defined as that that intensity of physical activity during which the person cannot speak more than a few words continuously. Athletes combine moderate and vigorous levels of physical activity alternatively (also called high intensity interval training – HIIT) for further enhancing the cardioprotective effects.

Gut microflora may influence the efficacy of blood pressure lowering medications according to recent research published in the AHA flagship journal Hypertension. Coprococcus Comis is a normal gut microbe in rats. The study found that this microbe had the potential to deactivate ACEI drugs and could thus render them less effective. More research is needed in humans but this study could be a pointer in the right direction in finding appropriate solutions for “resistent hypertensives” (a group of people whose blood pressure is difficult to control despite adequate antihypertensive medications)

Applying artificial intelligence to an Apple Watch ECG can reliably identify left ventricular dysfunction (heart failure) according to researchers at the Mayo Clinic. LV dysfunction affects approximately 9% of adults above the age of 60 years. ECG features of possible heart failure include prolonged QRS duration, delayed intrinsicoid deflection, the hump sign of ST-T, LBBB, LVH, LAD. An analysis of these findings along with application of AI can reliably predict LV dysfunction according to the authors of the study.

The amount of fat in and around your liver may be an indirect marker of your risks of adverse cardiovascular events in the future according to a recent scientific statement of the American Heart Association. Nonalcoholic Fatty Liver Disease (NAFLD) is a condition which causes accumulation of fat in and around the liver. This excess fat then leads to inflammation, scarring and finally liver failure if left untreated for a long time. The severity of NAFLD is also an indirect marker for adverse cardiovascular events in the future according to a recent scientific statement of the AHA.

Fitbit is a popular manufacturer of wearables that track cardiovascular and general fitness levels. The company has recently received FDA approval for for its photoplethysmography feature, the inbuilt algorithm and the associated app for its ability to accurately diagnose atrial fibrillation in adults. Atrial fibrillation is one of the most common heart rhythm disorders in adults and can result in a variety of complications including strokes if left untreated.

Patients with heart failure are often told to restrict their fluid intake to prevent worsening of their heart failure. While this may be true, recent research, published in the European Heart Journal also suggests that dehydration, indicated by a serum NA+ level of >>143mEq/Lit may also be just as deleterious. Both dehydration and fluid overload are best avoided in patients with heart failure.

Do not wait for symptoms to appear before seeking treatment if you have a narrowing (stenosis) of the Aortic Valve. People who have been diagnosed to have severe aortic valve stenosis who do not have symptoms will still benefit from, early aortic valve replacement surgery because the procedure reduces the risk of death, myocardial ischemia, stroke and cardiac failure, according to the AVATAR (Aortic Valve Replacement Versus Conservative Treatment in Asymptomatic Severe Aortic Stenosis) trial results which were presented at the Scientific sessions of the American Heart Association and published in its journal “Circulation” recently.

Cardiovascular anaesthesiologists often have to work long hours in the operating room. This sometimes leads to chronic fatigue and “physician burn out”. In an attempt to regulate the working hours of anaesthesiologists some hospitals have authorized a second anaesthesiologist to take over the case after the working hours of the previous anaesthesiologist are over. In an interesting bit of research recently published in the Journal of the American Medical Association, it was found that when a case was handed over to a second anaesthesiologist, both the 30day mortality and the 1 year mortality were significantly higher than if the case was handled by the same anaesthesiologist from start to finish. It is a delicate balance between maintaining quality of care and minimising physician burnout and chronic fatigue among health care professionals.

What happens when 2 highly respected professional scientific bodies disagree in public with each others’ recommendations on a particular medical issue? What kind of a signal does it send out to practicing medical professionals across the world? Should such differences be discussed thread bare behind closed doors and a common consensus be arrived at which should then be made public as a consensus statement?
Well, such a public disagreement occurred recently when the President of the American Society of Nuclear Cardiology disagreed in public (on video) with the American College of Cardiology and the American Heart Association guidelines on the evaluation and diagnosis of chest pain.

The U.S. Food and Drug Administration has cleared Inclisiran (Leqvio) manufactured by Novartis to lower low-density lipoprotein cholesterol (LDL-C) with just two injections a year, after an initial loading dose and a second booster after three months. This new and promising drug provides sustained LDL-C reduction of up to 52% vs placebo according to Vas Narasimhan the CEO of Novartis. Currently approximately 16 million Americans are on Statins to lower their LDL cholesterol levels. Inclisiran reduces LDL-C levels in the blood by enhancing the ability of the liver to prevent the production of a protein that plays a key role in keeping circulating cholesterol levels high. Inclisiran will be available for clinical use from mid January 2022. Read more.
