Heart disease is the leading cause of death in this country; more than 600,000 Americans die from the condition each year.

But there are ways to lower your risk, including maintaining a healthy body weight. Obesity adds strain to the heart and increases the risk for diabetes.

It happens without warning – every 43 seconds, someone in the US will have a heart attack.

How can you lower your risk?

First up: don’t smoke! People who do are up to four times more likely to develop heart disease.

“Cigarette smoking is probably one of the biggest risk factors for the development of plaque,” said William Quinones-Baldrich, MD, vascular surgeon at UCLA.

Next, make sure you’re getting enough sleep! One study found every extra hour of sleep in middle age can reduce the risk of coronary artery calcification by 33 percent. Aim for seven to eight hours.

Also, up your vitamin D. Too little can raise the risk of peripheral arterial disease by 80 percent.

Next, consume more omega-threes.

“Fish, salmon is great,” Quinones-Baldrich said.

Having just one serving of fish high in omega-threes a week could reduce your risk of death from a heart attack by 52 percent!

Lastly, drink wine and have more sex – you heard it right! Red wine in moderation contains antioxidants and flavonoids, which may reduce the risk of heart disease. And sex can lower blood pressure. One study found men who had sex at least twice a week were less likely to develop heart disease compared to those who had sex once a month.
