Long term exposure to specific air pollutants and road traffic noise significantly increases the risk of heart failure, especially especially among smokers or people with high blood pressure according to a study recently published in the Journal of the American Heart Association. This was a prospective study of over 22,000 participants of the all-female Danish Nurse Cohort study. Participants were 44 years of age or older and lived in rural, urban and suburban Denmark. The yearly average concentrations of two commonly used indicators of pollution, fine particulate matter (PM2.5) and nitrogen dioxide (NO2), were serially measured. Road traffic noise levels within a three-kilometer radius from the participants’ residential addresses were estimated using the Nord 2000 system.
The study found:
- For every 5.1 µg/m3 increase in fine particulate matter exposure for three years, the risk of cardiac failure increased by 17%.
- For every 8.6 µg/m3 increase in NO2 exposure for more than three years, the risk of cardiac failure increased by 10%.
- For every 9.3 dB increase in road traffic noise exposure for more than three years, the risk of cardiac failure increased by 12%.

The value of diet and exercise in the control of blood pressure is well known. An appropriate diet and exercise are beneficial even in “resistent hypertension” according to the results of the TRIUMPH study (Treating Resistant Hypertension Using Lifestyle Modification to Promote Health) that has recently been published in the journal Circulation. Resistant hypertension (RH) is defined as blood pressure that remains above the treatment goal (systolic blood pressure ≥130 mm Hg or diastolic blood pressure ≥80 mm Hg), despite documented adherence to a regime of 3 or more optimally dosed anti hypertensive drugs of different classes, one of which is a diuretic. Resistent Hypertension affects ≈5% of the general population and 20% to 30% of hypertensives

Atherosclerosis is the underlying mechanism for developing Coronary Artery Occlusive Disease later in life. A study that was recently published in the journal “Circulation” attempted to determine the prevalence of silent / subclinical atherosclerosis in the general population and concluded that in Sweden where the study was conducted over 40% of participants in the study who had no previous known risk factors for Coronary Artery Disease, had evidence of subclinical / silent atherosclerosis. The surprising findings of the study call for aggressive primary prevention to retard progression to full blown Coronary Artery Disease.

Even a single glass of wine can rapidly (within a few hours) raise the drinkers risk for atrial fibrillation as per the results of a recent study involving over 100 patients published in the Annals of Internal Medicine. The findings of this study contradict the prevalent view that moderate alcohol consumption has a cardio-protective effect. The study concluded that a single episode of atrial fibrillation was associated with two-fold higher odds with one alcoholic drink, and three-fold higher odds with two or more drinks within the preceding four hours. These episodes were also associated with a higher concentration of alcohol in the blood.

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

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.

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

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.

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.
