Broken-heart syndrome (takotsubo cardiomyopathy)

Takotsubo cardiomyopathy, also called broken-heart syndrome, is a weakening of the left ventricle that is usually the result of severe stress. Its symptoms resemble those of a heart attack, and treatment is usually the same as that for heart failure.

Exercise can lower resting heart rate and raise maximum heart rate to reduce the risk of heart attack and death.

Can we reduce plaque buildup in arteries?

Making plaque disappear is not possible, but it is possible to shrink and stabilize it. Drugs called statins can help with this, and so can eating a heart-healthy diet, exercising, and quitting smoking.

A look at diastolic blood pressure

When it comes to managing blood pressure, doctors tend to focus on lowering the top (systolic) number, but the bottom (diastolic) number also plays an essential role in heart health. Diastolic pressure is the pressure during the resting phase between heartbeats, and helps coronary vessels supply oxygen to the heart muscle. It's important to keep both blood pressure numbers low per guidelines, but research suggests the diastolic number should not fall too low.

Take-home advice from the new cholesterol guidelines

What can cause an enlarged heart?

An enlarged heart has many possible causes, including conditions that force the heart to work harder than usual (such as chronic high blood pressure or heart valve problems) and different types of cardiomyopathy (heart muscle disease).
