Can obesity cause dilated cardiomyopathy?

Can obesity cause dilated cardiomyopathy?

Obesity cardiomyopathy and systolic function: obesity is not independently associated with dilated cardiomyopathy.

Is idiopathic dilated cardiomyopathy hereditary?

Idiopathic DCM is considered familial when more than one first degree relative has been diagnosed with DCM or had a sudden cardiac death at a young age [1]. DCM is inherited in 20%-50% of cases [2-4] and abnormalities are frequently seen on echocardiogram in asymptomatic relatives [3].

How does obesity cause cardiomyopathy?

The most important mechanisms in the development of obesity cardiomyopathy are metabolic disturbances (insulin resistance, increased free fatty acid levels, and also increased levels of adipokines), activation of the renin–angiotensin– aldosterone and sympathetic nervous systems, myocardial remodeling, and small-vessel …

What is a dilated ventricle?

Dilated cardiomyopathy is a disease of the heart muscle that usually starts in your heart’s main pumping chamber (left ventricle). The ventricle stretches and thins (dilates) and can’t pump blood as well as a healthy heart can. Over time, both ventricles may be affected.

What causes cardiomyopathy?

Viral infections in the heart are a major cause of cardiomyopathy. In some cases, another disease or its treatment causes cardiomyopathy. This might include complex congenital (present at birth) heart disease, nutritional deficiencies, uncontrollable, fast heart rhythms, or certain types of chemotherapy for cancer.

What is the life expectancy of someone with dilated cardiomyopathy?

Clinically, DCM is characterized by a progressive course of ventricular dilatation and systolic dysfunction. The life expectancy is limited and varies according to the underlying etiology with a median survival time of about 5 years after diagnosis.

What weight is considered obesity?

This calculator provides body mass index (BMI) and the corresponding BMI weight status category for adults 20 years and older….Adult BMI Calculator.

BMI Weight Status
Below 18.5 Underweight
18.5—24.9 Healthy
25.0—29.9 Overweight
30.0 and Above Obese

What obesity does to the heart?

How does obesity increase the risk of heart and circulatory diseases? Being overweight can lead to fatty material building up in your arteries (the blood vessels that carry blood to your organs). If the arteries that carry blood to your heart get damaged and clogged, it can lead to a heart attack.

Can you live a long life with dilated cardiomyopathy?

Dilated cardiomyopathy is a common condition, and the majority of affected people remain well and have few or no symptoms. Research has shown that, with proper treatment and follow-up, most people with the condition live a normal life.

What are the genetic determinants of dilated cardiomyopathy?

Dilated Cardiomyopathy: Genetic Determinants and Mechanisms Nonischemic dilated cardiomyopathy (DCM) often has a genetic pathogenesis. Because of the large number of genes and alleles attributed to DCM, comprehensive genetic testing encompasses ever-increasing gene panels.

What is idiopathic dilated cardiomyopathy ( IDC )?

Idiopathic dilated cardiomyopathy (IDC) is a primary myocardial disease of unknown cause characterized by left ventricular or biventricular dilatation and impaired myocardial contractility1.

Who is most at risk for dilated cardiomyopathy?

It is the most common type of cardiomyopathy and typically affects those aged 20 to 60. [2] The left ventricle of affected individuals becomes enlarged (dilated) and cannot pump blood to the body with as much force as a healthy heart can.

What causes familial dilated cardiomyopathy ( TTN )?

Familial dilated cardiomyopathy is most often inherited in an autosomal dominant pattern. Familial dilated cardiomyopathy is caused by mutations in several different genes, most commonly in the TTN gene (found in about 20% of cases).
