Half of Heart Attacks are Symptomless, Study Says

You have not heard of ‘silent’ heart attacks, but they’re as deadly as any other heart disease. They show no symptoms, are characterized by a loss of blood flow (like any other heart attack) – and triple the chances of dying from heart disease.

It’s more prevalent than you’d think, too – they make up 45% of all heart attacks, according to a study published in the American Heart Association’s Circulation. They also increase the chances of all death by all causes by 34%.

The study, which examined 1,000 patients, reported men suffer from silent heart attacks more than women, but weren’t as deadly to them.

Silent heart attacks are typically undetected, and can go unnoticed until a patient has an electrocardiogram to measure the heart’s electric activity.

“The outcome of a silent heart attack is as bad as a heart attack that is recognized while it is happening,” said lead author Elsayed Z. Soliman in a statement accompanying the release of the study.

“And because patients don’t know they have had a silent heart attack, they may not receive the treatment they need to prevent another one.”
