Q1. Is it true, that heart attack risks rises in winter?
    Heart problems tend to increase by 30- 40% in winter compared to the month of summer. There is a constant risk of heart attacks of about 2%, with every mercury dip of 1-degree centigrade in temperature.

 

  Q2. What are the major reasons behind the increase of heart problems?    
     1.   During winter, there are more constrictions of blood vessels including coronary arteries which supply blood to heart muscle.
     2.   There is increase in blood viscosity (thickness) and blood clotting tendency in cold weather.
     3.   Winter can increase the heart and blood pressure rates leading to heart attack.

Q4. Can environmental changes lead to heart diseases?
  In India, major cities are under the cover of smoke and pollution. Which tend to rise in winters, as seen in Delhi recently. These factors lead to blockages in blood vessels supplying the heart resulting in heart attack. Respiratory infections in winter can create additional stress or worsen the heart problem.
