Final answer:
It is false that patients with coronary heart disease always experience pain; some may remain asymptomatic. Symptoms like chest pain can vary in presence and severity among individuals.
Step-by-step explanation:
The statement that patients with coronary heart disease always experience pain is false. While a common symptom of coronary heart disease is chest pain, known as angina pectoris, not all individuals with the disease experience pain. Some might remain asymptomatic for years, which means they don't exhibit any symptoms.
Coronary heart disease results from the build-up of plaque in the coronary arteries through a process called atherosclerosis, which can lead to a range of cardiovascular diseases including angina and myocardial infarction, more commonly known as a heart attack. The disease can have serious complications if left untreated, but the manifestation of symptoms like chest pain is not universal among all sufferers. The variety of symptoms and their severity can vary greatly from person to person.
