Heart Attack in Winters more deadly then Summers

According to a recent research presented at the British Cardiovascular Society Conference 2018, stated that Heart Attacks which happens in the winter season are more deadly than the winter season.

The research was conducted on the 4,056 patients at Leeds General Infirmary over four years, where the cardiologist observed those patients and they found the most severe heart attacks were more deadly in the coldest six months, compared to the warmest. The rate of the cardiac arrest patient was same in the winter season as compared to the summer seasons with the most serious heart attacks leading to cardiac arrest and cardiogenic shock.

What is Cardiac Arrest and Cardiogenic Shock?

Cardiac arrest is when the heart suddenly stops pumping blood around the body, while cardiogenic shock is when the heart can’t pump enough blood to meet the body’s needs. Both conditions are often caused by a severe heart attack, but not everyone who has a heart attack has a cardiac arrest or cardiogenic shock.

Cardiologists looked at the 30-day mortality rate for patients suffering from the most serious heart attacks and they found the risk of dying in the six coldest months was almost 50 percent higher as compared to the six warmest months (20% to 28%)

Dr Krishnamurthy who led the research stated that there is no physical reason why a heart attack, even the most severe, should be more deadly in winter than in summer so we must do further research to find the cause of this difference and remedy it. Potential explanations could include longer time to treatment, prolonged hospitalisation and delays to discharge, and increased prevalence of winter-associated infections, which in the sickest patients, could be potentially lethal.
