In the developed world, it is one of the leading causes of death both in men and women. Around 94,000 deaths each year in the UK are attributed to this condition and the prevalence of this condition is about 2.6 million. The most common symptom associated with coronary heart disease (CHD) is angina and about 2 million people are affected with it each year. With age the prevalence and severity of CHD would only increase (NHS 2009). The two most notable conditions that are associated with CHD are angina and myocardial infarction. Myocardial infarction arises when coronary arteries are completely blocked and angina arises when the coronary arteries are partially blocked. Some of the common symptoms that are associated with CHD include breathlessness, chest pain, palpitations, a feeling of heaviness or tightness over the chest, sweating, confusions, anxiety, light-headedness, breathlessness, and dyspnea. Some of the common complications that can arise with the progression of CHD include heart attack, angina, heart failure, and arrhythmia (Mayo Clinic 2012).
The main pathophysiology associated with CHD is the build-up of plaque in the coronary artery. As the plaque builds up, the lumen of the vessel becomes narrower, and so does the heart receive reduced supply of blood, resulting in the development of several symptoms of CHD including chest pain, breathlessness, and light-headedness. ...Show more
