Heart disease is a broad term used to describe the conditions that affect the heart, the circulatory system as well as conditions that affect both simultaneously. Medically, heart diseases are referred to as cardiovascular disease.

Heart disease is a matter of concern as the heart is the most important organ of the body. It not only affects older people, but can occur as a congenital condition as well as affect people irrespective of their age or sex.

What is  Heart Disease?

Heart is the center of the entire cardiovascular system. The disease that affect the heart and blood vessels leads to many problems. Heart disease can strike suddenly, causing one to take life changing decisions in a short span of time. Thus, it is very important to know about some of the common heart diseases and how they can affect your overall health.

Types of Heart Disease

There are many different types of heart diseases. Some of these are covered in the following paragraphs.

Cardiovascular Conditions

Hypertensive heart disease

High blood pressure causes stress to the heart and blood vessels. It increases the risk of atherosclerosis and ischemic heart disease. Early diagnosis of high blood pressure can keep the condition in control and prevent occurrence of heart diseases. Change in lifestyle, diet, exercises, weight loss, quit smoking, etc. are ways to prevent high blood pressure and keep hypertensive heart diseases at bay.

Coronary heart disease

Also known as coronary artery disease (CAD) or atherosclerotic heart disease, it is one of the most common causes of heart attacks. Plaque lines up the walls of the heart arteries, leading to narrowing of the arteries as well as their blockage. This reduces the blood supply to the heart, leading to symptoms of coronary artery disease. In many, the symptoms never show up and leads to a ‘sudden’ heart attack. In most cases, this sudden heart attack proves fatal.


Disease of the heart muscle that leads to heart failure is called as cardiomyopathy. The condition often leads to breathlessness, swelling of the legs, irregular heart beat and sudden cardiac arrest that is fatal in most cases.

Cardiac dysrhythmia

Also called as an irregular heartbeat or arrhythmia, it is a condition that causes the heart to beat too fast or slower than normal. The heart may beat more than 100 beats/min or less than 60 beats/min.

An arrhythmia can be atrial (upper chamber of the heart) or ventricular (lower chamber of the heart). Some can lead to sudden cardiac arrest and prove to be life threatening.

Valvular heart disease

Valvular heart disease is a condition that can affect one or more of the four heart valves. These heart valves include the aortic, mitral, pulmonary and the tricuspid valve. Valvular heart diseases can occur as a congenital problem or acquired condition. The treatment of this condition usually involves valve repair or replacement.

Cerebrovascular disease

Cerebrovascular disease is the condition that affects the blood vessels that supply blood to the brain. The heart and the brain are the two most important organs of the body. Damage to either of these organs can lead to life altering results. Diseases that are included in the group of cerebrovascular diseases include:

These conditions may lead to damage to the eye leading to:

  • Blindness
  • Facial weakness
  • Mental confusion
  • Numbness in any part of the body
  • Loss of speech
  • Impaired speech
  • Paralysis, etc.

Congenital heart disease

Congenital heart anomaly is a condition where the heart and the hreat vessels have a defect at birth. This causes problems with the blood flow within the heart and the nearby blood vessels. It is one of the most common causes of birth defect-related deaths. However, most conditions can be treated by medications and surgery. There are many types of congenital heart diseases that can either occur due to genetic mutations or environmental effects.

Peripheral vascular disease

Also referred to as peripheral artery disease, this condition occurs due to an embolism, thrombus or stenosis. It often leads to sores and wounds that do not heal, blueness or paleness in the affected limb, pain, weakness, cramping, etc. in the affect limb due to decrease in blood flow.

Rheumatic heart disease

An inflammatory disease of the heart that occurs due to an infection with Streptococcus pyogenes. It leads to inflammation of the heart muscles, leading to congestive heart failure. Other symptoms affecting the heart due to rheumatoid heart disease include shortness of breath, heart murmur and pericarditis.

Risks That Lead to Heart Diseases

There are several risk factors that increase one’s chances of developing heart diseases. These include:

  • Smoking
  • Alcoholism
  • High blood pressure
  • High levels of blood cholesterol

When they do visit a doctor for a routine health check up, they find out they have a heart disease waiting to explode. These tests that help detect heart and vascular diseases include:

How Are Heart Diseases Treated?

Medications, change in lifestyle and surgery in some cases helps treating heart diseases. Statins and aspirin are medications commonly used in case of heart diseases. Surgeries include:
