According to the WHO, heart disease refers to a wide range of disorders that specifically affect the organ heart. Heart disease occurs in different forms with the most common heart disorder in the United States being the malfunction of arteries supplying blood to the heart muscles (coronary heart disease). According to CDC data of 2017, coronary heart disease killed an estimated 365,914 people in the US
According to the CDC report 2019, heart disease causes 25% of the total deaths experienced in the US per annum. 25% of total deaths in the US per annum accounts for approximately 647,000 deaths which in turn translates to 1 death in every 37 seconds. In every year beginning 2014 -2015, the US is estimated to incur costs amounting to $219 billion on medicine, healthcare services and decline in productivity. Apart from coronary heart disease, other conditions include;

Damage of the heart valves by rheumatic fever (rheumatic heart disease)
Deformities of the heart developed before birth, such as hole between heart chambers, partial or permanent blockage of blood flow in certain chambers, low oxygen around the body (Cyanotic heart disease).
Heartbeats are irregular, abnormal, faster or slower (arrhythmia)
Limited pumping of blood due to thickening of the walls of the left ventricle (Hypertrophic cardiomyopathy).
The right ventricle is unable to pump blood (Pulmonary stenosis).
Inability to pump sufficient blood to the body (Heart failure).
Often, heart disease remains silent and may not be diagnosed until the appearance of signs and symptoms suggesting heart attack, heart failure, or an arrhythmia. According to CDC, the signs and symptoms include; chest pain, dizziness, severe fatigue, pain in the neck and upper back, heartburn, discomfort in the upper body, short breath, palpitations, swelling of legs/ankles/feet/veins in the neck region, vomiting/nausea, profuse sweating, travelling pain in different body parts and clubbed fingernails.
According to the World Health Organization, heart disease can be prevented through avoiding exposure to high-risk factors that include high cholesterol in the blood, high blood pressure, diabetes, obesity, overweight and smoking. High cholesterol and blood pressure can be avoided by adopting a healthy diet, regular physical exercises, and avoiding excessive alcohol abuse.
