High resistance inspiratory muscle training is a method to strengthen inspiratory muscles of the chest and the diaphragm by breathing in against mild resistance. This has been found to also reduce the blood pressure significantly, allowing hypertensives to use the technique for good non pharmacological blood pressure control. The results of this study were recently published in the Journal of the American Heart Association.

The risk of developing high blood pressure later in life can now be predicted using a simple blood test (fasting blood triglyceride level) and an anthropometric (waist circumference measured midway between the 12th rib and Iliac crest in full expiration) measurement. The Lipid Accumulation Product (LAP) is a widely used marker to predict the risk of metabolic disorders and cardiovascular diseases. It has been found to be useful in predicting the risk of hypertension as well according to a recent study published in the journal Nature. LAP values for men and women can be calculated using fasting Triglycerides levels in mmol/L and waist circumference in cm as follows:
in women, LAP = (WC-58) × fasting TG level
in men, LAP = (WC-65) × fasting TG level
LAP >27cm/mmol in women and 27.6cm/mmol were highly predictive of development of hypertension in the future.

Out of hospital cardiac arrests have a relatively high mortality and also strain the emergency department and ambulance services of a region. According to a new study published in the British Medical Journal, artificial intelligence could be used to predict the occurrence of cardiac arrests in a community and could potentially lead to better allocation of medical and paramedical resources in the region. The researchers looked at the ability of machine learning to predict out of hospital cardiac arrests, using weather (temperature, relative humidity, rainfall, snowfall, cloud cover, wind speed and atmospheric pressure readings) and timing (year, season, day of the week, hour of the day, and public holidays) data that is readily available from multiple sources. The risk of a cardiac arrest was highest on Sundays, Mondays, public holidays and when temperatures dropped sharply within or between days. This information could potentially be used as an warning system for citizens according to the researchers

The beneficial effects of Omega 3 fatty acids on the heart have been researched extensively. They are supposedly very beneficial in people with elevated triglyceride levels. A recent report published in the European Heart Journal(a meta analysis of many RCTs) however finds that there is an increased incidence of atrial fibrillation in people on Omega 3 fatty acid supplements. These supplements should therefore not be taken without adequate medical supervision.

Preconditioning is a method of inducing short periods of relative ischemia followed by reperfusion in the myocardium so that it tolerates longer periods of ischemia (such as during CABG) well. Pre CABG high dose atorvastatin (80mg) was found to be beneficial in achieving good preconditioning in patients scheduled for elective CABG according to a recent publication in the Annals of Cardiac Anaesthesia.

HDL cholesterol (the “good” cholesterol) is well known to have significant cardioprotective actions. A recent publication in the journal Circulation found that high HDL levels are associated with higher anti-inflammatory actions as well. Chronic inflammation is one of the most well documented underlying mechanisms in various disease and accelerated aging. Good cholesterol has anti-aging properties as well.

If young women have any of the following 6 pregnancy related complications:
- high blood pressure,
- gestational diabetes,
- preterm delivery,
- small-for-gestational-age delivery,
- pregnancy loss
- placental abruption
their risks for developing cardiovascular disease later in life are significantly higher according to a new scientific statement from the American Heart Association, published the journal Circulation. The statement urges active prevention of these risk factors along with primary prevention of Cardiovascular Disease for women who have any of these complications in pregnancy.

Ultra high processed foods account for approximately 58% of the total energy in the average American diet. A recently published study by Ms Filippa Juul of the New York University School of Public Health in the Journal of the American College of Cardiology, found that high consumption of ultra high processed foods are associated with an increased risk of cardiovascular disease. Each additional serving was found to compound this risk further.

People with high blood pressure may benefit most with specific personalised exercise recommendations according to the European Society of Cardiology. according to recent research found that specific exercises helped to bring down the blood pressure in hypertensives. This is a slightly different reccomendation from the 30minutes of moderate exercise 5 days a week which has been championed by the American Heart Association.

Heart attacks are more likely to be missed in women according to recent research presented at the ESC Acute Cardiovascular Care 2021 online congress recently. Women, particularly diabetics need to be extra careful and treating physicians must have a high index of suspicion of a cardiac etiology in women who may present to them with atypical chest pain.

AI can now predict the possibility of atrial fibrillation according to a recent study published in the journal Circulation. The authors used 1.6 million ECGs from 4,30,000 patients (with no previous history of atrial fibrillation) to train deep neural networks to predict new onset atrial fibrillation. The model was found to predict new onset atrial fibrillation within one year impressively with a sensitivity of 69% and specificity of 81%. It could also categorize patients into high risk and low risk groups

Control of cardiovascular risk factors could delay or prevent the onset of dementia according to a recent editorial in the Journal of the American College of Cardiology. Cerebral atherosclerosis is one of the postulated mechanisms for the development of dementia. The pathophysiology of atherosclerosis in the heart and brain is similar. The study concluded that control of risks factors that apply to heart disease also prevented or significantly delayed the onset of dementia in the study participants.

Consumption of large amounts of refined grains is related to increased cardiovascular morbidity according to recent research published in the British Medical Journal. The authors classified grains into 3 types – refined grains, whole grains and white rice. Refined grains included foods made using refined (e.g. white) flour, including white bread, pasta, noodles, breakfast cereals, crackers etc. Whole grains included whole grain flours like buckwheat. White rice was grouped alone. The study concluded that more than seven servings of refined grains everyday day was associated with a 27% risk for early death, a 33% percent greater risk for heart diseases and 47% risk of stroke.

Moderate consumption of alcohol has previously been shown to have some cardio protective effects. A recent study published in the European Journal of Cardiology however has some startling contrarian findings. According to this study moderate consumption of alcohol is associated with a sharp increase in the incidence of atrial fibrillation. The study makes a compelling case for abstinence for preserving heart health

Carrots are rich in beta carotene which is converted into vitamin A in the body. Adequate levels of vitamin A are necessary for normal vision and integrity of mucosal surfaces. There is however another beneficial effect of conversion of beta carotene to vitamin A. This conversion simultaneously reduces LDL cholesterol thus lowering the risk of atherosclerosis. A diet rich in beta carotene is associated with lower levels of LDL cholesterol. These findings have recently been published in the Journal of Lipid Research.
