Most people with HCM inherited the genetic mutations from their parents, but the mutations can also occur spontaneously. These mutations can pass directly from parent to child; they do not skip a generation. The likelihood of a parent passing the mutation on to a child is about 50 percent.

Hypertrophic cardiomyopathy is usually passed down through families (inherited). If you have a parent with hypertrophic cardiomyopathy, you have a 50% chance of having the genetic mutation for the disease.

The genetic risk for HCM is passed from one generation to the next by way of dominant-acting mutations in genes governing the structure of the heart muscle. That means that first-degree relatives (parents, siblings, and children) of an affected person have a 50% chance of having inherited the same mutation.

Research has shown that with proper treatment and follow-ups, most people with HCM live a normal life. A database of 1,297 patients with HCM from the Minneapolis Heart Institute Foundation identified that 2% of the patients can live past 90 years, and 69% of them were women.

Heart Disease Does Not Have to be a Death Sentence. Hypertrophic cardiomyopathy, or HCM, is the most common heart disease diagnosed in cats.

It occurs in about 1 out of 100 adults with hypertrophic cardiomyopathy each year. Sudden death is often the result of ventricular tachycardia (a type of rapid heart rate) or other dangerous arrhythmias, which can be caused by hypertrophic cardiomyopathy.

One of the most serious manifestations of HCM, apart from sudden death, is progressive systolic heart failure (HF) often coupled with ventricular dilatation, which for the lack of a better name, is referred to as end-stage HCM.

Ventricular fibrillation is one type of arrhythmia that can be deadly. It occurs when the heart beats with rapid, erratic electrical impulses. This causes the lower chambers in your heart (ventricles) to quiver uselessly instead of pumping blood.

Hypertrophic cardiomyopathy (HCM) is considered a leading cause of sudden cardiac death (SCD) in younger people. The incidence of HCM-related SCD and its relationship to exercise have not been well studied in large comprehensive studies outside of tertiary care settings.

As many as 1 of 500 adults may have this condition. Males and females of all ages and races can have cardiomyopathy. Dilated cardiomyopathy is more common in blacks than in whites and in males than in females. Hypertrophic cardiomyopathy is thought to be the most common inherited or genetic heart disease.

Hypertrophic cardiomyopathy (HCM) is a genetically transmitted disease with a variable clinical course and outcome. In many series, annual death rates are as high as 3–6%,1,2,3,4 but recent studies from centres in Europe and the USA report a substantially better prognosis with overall mortality of 1% or less.

The rates of freedom from death related to hypertrophic cardiomyopathy were 98% at 5 years and 94% at 10 years, which are not significantly different from expected all-cause mortality in the general population (P = . 25), Maron and colleagues found.

Limit Alcohol Consumption NYU Langone doctors recommend that people with this condition limit or avoid alcohol. Alcoholic drinks can worsen obstruction in the heart, which reduce blood flow to the body. Alcohol consumption can also promote weight gain, which can worsen symptoms.

Cardiomyopathy can be life-threatening and can shorten your life expectancy if severe damage occurs early on. The disease is also progressive, which means it tends to get worse over time.

When a cardiomyopathy causes severe heart failure (e.g., ejection fraction <30%), patients may qualify for Social Security disability benefits under listing 4.02. Patients with cardiomyopathy who have coronary artery disease may qualify under section 4.04.
