Cardiologist Warns H1N1 Flu Can Trigger Serious Heart Complications
A cardiologist says the H1N1 flu can sometimes hurt the heart.
It may lead to a heart attack, myocarditis, or heart failure.
This can happen even to people who did not already have heart problems.
When the body fights the flu, the immune system becomes very active.
That can make the heart work harder.
Fever and dehydration can add more strain.
Less blood may then reach the heart and other organs.
These problems can make a sick person’s condition worse.
A cardiologist says H1N1 influenza may trigger heart attacks, myocarditis and heart failure.
Heart complications can affect people without a previous heart-related diagnosis.
Influenza can activate the immune system throughout the body, increasing stress on the heart.
Fever and dehydration may make the heart work harder to pump blood.
Reduced blood flow to the heart and other organs can worsen patients’ condition.
