Do athletes have left ventricular hypertrophy?

Physiological left ventricular hypertrophy (athlete’s heart) or hypertrophic cardiomyopathy. A small minority of highly trained athletes exhibit substantial LVH, with values between 13 and 16 mm, which overlaps with values observed in 10–15\% of patients with morphologically mild HCM.

Does exercise cause left ventricular hypertrophy?

In contrast, combined isotonic and isometric exercise (e.g., weight training and rowing) may lead to substantial hypertrophy of the left ventricular wall. Nevertheless, exercise-induced left ventricular hypertrophy is considered a normal physiologic adaptation to the particularly rigorous training of athletes.

What does left ventricular hypertrophy mean?

Left ventricular hypertrophy is a thickening of the wall of the heart’s main pumping chamber. This thickening may result in elevation of pressure within the heart and sometimes poor pumping action. The most common cause is high blood pressure.

What is the difference between an athlete’s heart and left ventricular hypertrophy?

Most individuals with HCM have a small left ventricular cavity (<45 mm), while athletes with physiological LVH have concomitant enlargement of the left ventricular cavity. Some experts feel that left ventricular cavity size is the single most important discriminator between physiological LVH and HCM.

Can exercise reverse left ventricular hypertrophy?

Losing weight has been shown to reverse left ventricular hypertrophy. Keeping a healthy weight, or losing weight if you’re overweight or obese, can also help control your blood pressure.

What does exercise do to the left ventricle?

The left ventricle fills with blood and twists to send it throughout the body every time the heart pumps. As you exercise more, your left ventricle becomes stronger, bigger, and more efficient at sending oxygenated blood out.

Why do athletes have a lower heart rate than non athletes?

That’s likely because exercise strengthens the heart muscle. It allows it to pump a greater amount of blood with each heartbeat. More oxygen is also going to the muscles. This means the heart beats fewer times per minute than it would in a nonathlete.
