There are few life-saving medical devices as well known as the pacemaker. More than a million of them are implanted each year, providing peace of mind for people whose hearts don’t beat as they should. 

Throughout the day, your blood pressure can rise and fall based on your activities. But when it stays abnormally high for too long — a condition called hypertension — it can cause health problems, including heart damage.

Exercising may not be the first thing you think about if you’ve had a heart attack, heart failure, stent replacement or angioplasty or other heart issues. You may break into a sweat just thinking about intentionally raising your heart rate as you recover emotionally and physically. Will your heart withstand the stress of exercise?

When should you start – or stop – taking low-dose aspirin to prevent heart disease and stroke? 

Transcatheter aortic valve replacement (TAVR) has been used since 2011 for patients with a narrowing of the aortic valve opening (aortic stenosis), whose age or poor health made it unlikely they could survive traditional open-heart surgery. But two new clinical trials indicate that TAVR also can be used in younger, healthier patients.  These results will significantly change how doctors treat patients who have failing aortic valves.

Less than a decade ago, if you had severe narrowing of the aortic valve opening in your heart (aortic valve stenosis) or a severe leak in the aortic valve (aortic regurgitation) standard treatment would be open heart surgery to replace the malfunctioning valve. Fortunately, in 2011, the United States Food and Drug Administration (FDA) approved TAVR as a minimally invasive way to replace the aortic valve. This became a game changer, particularly for those who were not good candidates for traditional open heart surgery.
