A recent study has revealed that common viral infections such as the flu can also increase the risk of heart attack.
1. Inflammation in the Body:
When the body fights a viral infection such as the flu, coronavirus, or even the common cold, the immune system becomes active. This increases inflammation, which can damage the walls of blood vessels and accelerate the process of atherosclerosis (fat buildup in the arteries).
2. Risk of Blood Clotting:
Some viral infections make the blood thicker, increasing the likelihood of clot formation. If these clots block the arteries of the heart, it can lead to a heart attack.
3. Lack of Oxygen:
Certain viruses cause respiratory illnesses that reduce the oxygen levels in the body. The heart has to work harder, and if a person already has heart disease, the risk increases further.
4. Direct Impact on Heart Muscles:
Some viruses can directly attack the heart muscles, a condition known as myocarditis. This can also affect heart function and produce symptoms similar to those of a heart attack.
