Which cardiomyopathy causes sudden death in athletes?

Hypertrophic cardiomyopathy (HCM). Hypertrophic cardiomyopathy, although not usually fatal, is the most common cause of heart-related sudden death in people under 30. It’s the most common identifiable cause of sudden death in athletes.

Can hypertrophic cardiomyopathy cause sudden death?

HCM can lead to sudden cardiac death (SCD), mainly due to ventricular tachyarrhythmia or ventricular tachycardia. High-risk patients benefit from implantable cardioverter-defibrillators.

What is the most common cause of death for patients with hypertrophic cardiomyopathy?

Sudden cardiac death (SCD) is a relatively common cause of mortality in patients with HCM. It is caused by fatal arrhythmias which can be effectively treated with implantable cardioverter defibrillators (ICDs).”

Can you be an athlete with hypertrophic cardiomyopathy?

Current guidelines recommend restricting competitive sports participation for individuals with HCM to low-static/low-dynamic sports such as golf or bowling,1-3 and vigorous recreational exercise has also been recommended against.

What causes sudden cardiac death?

What causes sudden cardiac death? Most sudden cardiac deaths are caused by abnormal heart rhythms called arrhythmias. The most common life-threatening arrhythmia is ventricular fibrillation, which is an erratic, disorganized firing of impulses from the ventricles (the heart’s lower chambers).

Why do fit athletes have heart attacks?

In most cases, the athletes have an underlying heart abnormality that may have been inherited or remain undiagnosed, cardiologists say. “Exercise likely acts as a trigger,” Goodman said. “And the intensity of the exercise … may make that heart particularly vulnerable to an arrhythmia that can cause a lethal outcome.”

What population is at risk of sudden death from hypertrophic cardiomyopathy?

In summary, HCM was responsible for 1 in 30 SCAs in the young and middle-aged general population, which translated to an annual SCA incidence of 0.2% to 0.3% among unselected patients with HCM in the community.

What is hypertrophic cardiomyopathy in athletes?

Hypertrophic cardiomyopathy (HCM) is a genetic cardiovascular disease characterized by a hypertrophied, nondilated left ventricle (LV) in the absence of other causes. HCM is relatively common and is one of the most common causes of sudden death in athletes. HCM is genotypically and phenotypically heterogenous.

How common is sudden cardiac death in young athletes?

Sudden cardiac death (SCD) in a young person is a rare but tragic occurrence. The impact is widespread, particularly in the modern era of media coverage and visibility of social media. Hypertrophic cardiomyopathy (HCM) is reported historically as the most common cause of SCD in athletes younger than 35 years of age.

What is hypertrophic cardiomyopathy (HCM)?

Hypertrophic cardiomyopathy (HCM) is reported historically as the most common cause of SCD in athletes younger than 35 years of age. A diagnosis of HCM may be challenging in athletes as pathological hypertrophy of the left ventricle may also mimic physiological left ventricular hypertrophy (LVH) in response to exercise.

What is the pathophysiology of sudden death syndrome (ScD) in athletes?

Triggers such as extreme physical exertion coupled with a substrate like underlying structural heart disease constitutes the pathologic basis of SCD in athletes.[1,3] An age cutoff of 35 years delineates younger from older athletes.[4]

What is the prevalence of HCM in athletes?

HCM is relatively common and is one of the most common causes of sudden death in athletes. 1 HCM is genotypically and phenotypically heterogenous. 2, 3 The differential diagnosis for HCM includes physiological remodeling seen in athlete’s heart. 4 Distinguishing HCM from athlete’s heart is of critical importance.
