All kinds of cardiac disease or cardiovascular diseases like acute heart attack, stroke, atrial fibrillation, Deep vein thrombosis, heart failure, uncontrolled blood pressure.

Heart failure incidents are more because of the patient who are already having cardiac problems, the more hospitalization occur during winter months. It has been seen in one study -that those who are less than 60 year old, they tend to have heart attack more in summers -April and May months and those more than 60 they tend to have it in winters more as compared to others season.
