ECG readings taken with a smart watch may be just as accurate as a traditional ECG done in a medical setting. But the notion of using a smart watch to diagnose a heart attack is still years away. One main reason: obtaining an ECG with a smart watch requires carefully holding the back of the watch on the wrist and at eight specific locations on the chest and abdomen. Quality control and regulatory issues are other important hurdles that need to be addressed. But experts believe improved smart watches with enhanced diagnostic ability may be on the market within a decade.

A small amount of leakage (regurgitation) from the mitral or tricuspid valve is normal. People with either condition do not need to modify their activity levels, but they should stay alert to symptoms that suggest the problem is worsening.

High temperatures stress the body, leading to thousands of heat-related illnesses and deaths every year in the US. Learn when hot weather becomes dangerous and how to create your own hot weather safety plan.

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

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.

A double knee torso rotation stretches the back, chest, hips, and outer thighs. It also strengthens and stabilizes the core muscles, which are vital for good form and function in many sports.

Optimism and other positive emotions may guard against serious heart-related events and death. Simple exercises such as expressing gratitude and performing acts of kindness can counter depression and improve well-being. These interventions may encourage people—including those with heart-related conditions such as heart attacks and heart failure—to exercise more and take their medications more consistently. Having a more positive outlook may help reinforce other positive behaviors, or what psychologists refer to as the "upward spiral." This momentum can help people start healthy habits like exercise, which then becomes self-reinforcing.

Long-term exposure to traffic noise may boost the risk of high blood pressure. Such sounds as roaring engines, blaring horns, and wailing sirens can trigger stress and disrupt sleep, both of which may contribute to high blood pressure and other heart-related risks.
