The most common cause of a stiff, narrowed aortic valve (aortic stenosis) is a buildup of scar tissue and calcium on the valve. Factors that contribute to narrowing of this valve include age, an inborn valve defect, and various diseases such as kidney disease. Aortic stenosis can cause shortness of breath, fatigue, and lightheadedness, especially during physical activity.

Exercise may help to reverse some types of heart damage. Not only can workouts prevent heart problems, but it may help to improve conditions that may raise risk for cardiovascular events. A 2021 study, for example, showed that a yearlong exercise program helped improve heart health in people who were at increased risk for heart failure.

The most common type of heart failure in older adults is heart failure with preserved ejection fraction. This is caused by the heart's left ventricle not being able to relax, which means less blood enters the chamber, so less gets pumped out. Prevention and treatments continue to evolve, but include controlling blood pressure, addressing weight gain with exercise and diet, not smoking, and curbing alcohol intake.

A rapid heartbeat may be due to supraventricular tachycardia or ventricular tachycardia. The former is usually harmless, while the latter is more serious and more likely to occur in older people with heart disease.

Paying attention to changes in your body can help prevent a recurrence of heart failure.

Aortic stenosis is the narrowing of the aortic valve in the heart, which can lead to heart failure if the problem is not identified and treated. Unfortunately, research shows that inequities exist in access to proper diagnosis and care for this condition. Understanding how stenosis is identified and treated can help you receive good care.
