Heart patients should avoid stress in winter
All heart patients should have their cardiac and mental stress levels check up done in winter. A heart attack can come with irregular meals, late nights, missing of regular dose of medicines and indulgence in smoking and drinking, said Padmashri and Dr B C Roy National Awardee Dr KK AggarwalPresident Heart Care Foundation of India.
Acute stress related events are common during winter especially near full moon in the early morning hours. The circadian variation in event frequency suggests that cardiac events may be triggered by external activities, particularly those activating the sympathetic nervous system.
Data from the Multicenter Investigation of the Limitation of Infarct Size (MILIS) indicated that among 849 patients with acute heart attack 48 percent described one or more possible triggers, the most common of which was emotional upset (14 percent).
There are several mechanisms by which emotional stress might trigger an acute heart attack.
The physiologic changes that have been described in the morning period of enhanced cardiovascular risk — increase in blood pressure, heart rate, vascular tone, and platelet agreeability — also may result from mental stress.
These factors may all be related to abnormalities in autonomic tone and activation of sympathetic nervous system activity, which may enhance platelet aggregation and increase the susceptibility to serious ventricular arrhythmias.
