Valvular heart disease is a condition of the heart where there is damaged to your heart valves. There are many causes which can lead to valvular heart disease. If the disease is not inherent to you when you are born, the damage may because later on in life by different conditions such as disorders of your connective tissues, rheumatic fever, and infections in the heart such as infectious endocarditis.

Heart Infection

Heart infections are often caused by irritants which can lead you to suffer from pericarditis (inflammation of the pericardium), endocarditis (inflammation of the endocardium), or myocarditis (inflammation of the myocardium or heart muscle). The most common irritants that may cause such heart infections include bacteria, viruses, parasites, and other chemicals that may reach your heart’s muscle.

Heart Arrhythmia

Heart arrhythmia is also one of the most common conditions of the heart that a person may suffer from. There are different causes of cardiac arrhythmia, some can be controlled while some are not. The uncontrolled causes of heart arrhythmia include congenital heart defects from the day a person is born, coronary artery disease, and valvular heart disease. Meanwhile, some causes of heart arrhythmia which you can easily take control over are high blood pressure, diabetes, smoking, drug abuse, stress, excessive intake of alcohol or caffeine and over-the-counter medications, dietary supplements and herbal remedies.

If you are a healthy person with a normal and well-functioning heart, the fatal arrhythmia is unlikely to occur without an external factor such as illegal drug use or electric shock that may trigger the attack. But, if the heart has already some existing problems, diseases or deformation, the electrical impulses in the heart may find some problem and arrhythmias are likely to happen.

Congenital Heart Defects

Unfortunately, congenital heart defects usually start inside the womb, and the baby may carry it as he grows old. These defects develop during heart development while inside the mother’s womb about 4 weeks or a month after conception. It will change the blood flow in the heart of the baby. Heart defects may be caused by some medical conditions, medications taken by the mother, as well as genetic hereditary that may be passed on from one generation to another.

Heart defects may also happen in adults when the heart’s structure began to change due to aging which will cause certain heart deficiencies that may lead to major problems and heart diseases.


Cardiomyopathy is the thickening or enlarging of the heart muscle. What causes heart disease in cardiomyopathy often depends on its different types:

  • Dilated Cardiomyopathy. The most common type of cardiomyopathy and usually the cause is unknown. However, a possible caused may be an ischemic heart disease wherein there is a decrease blood flow to the heart. Other causes may also include infections, drugs and other toxins. Family history also plays a role in the risk factors and causes of dilated cardiomyopathy development.
  • Hypertrophic Cardiomyopathy. Just like most heart diseases, hypertrophic cardiomyopathy is often inherited. This is a condition where the heart muscle becomes unusually thick and may also develop due to aging and untreated high blood pressure.
  • Restrictive Cardiomyopathy. This is the least common type of all three cardiomyopathy cases. This can occur for no apparent reason which will result in heart muscle becoming rigid and less elastic. However, there is a possibility that it can be caused by other diseases such as hemochromatosis or the excessive build-up of iron in the body or connective tissue disorders. Cancer treatments like radiation and chemotherapy may also lead to the development of restrictive cardiomyopathy.
