Maintaining and monitoring heart health is important throughout the year but more so during winter as cold weather often precipitates heart attack, heart failure and increases blood pressure. This is important not only in middle-aged and elderly people but equally important even in younger people. 
Lately, we have seen many young people (younger than 40 years) to suddenly succumb to heart attacks. 

Sudden death in young people occurs due to heart attack which is more often due to a clot occluding the artery supplying blood to the heart (coronary arteries). In elderly people attack occurs due to a combination of underlying atherosclerotic narrowing with supper added clots while in youngsters it’s often due to only clots with no or minimal underlying narrowing. Smoking and tobacco are two main risk factors causing blood clots.
