Final answer:
Hypertension is a chronic condition with no symptoms. Mr. Jones' undiagnosed hypertension led to his myocardial infarction (heart attack). High blood pressure puts strain on the heart and can lead to serious cardiovascular issues.
Step-by-step explanation:
Hypertension is a chronic medical condition in which the blood pressure in the arteries is persistently elevated. It is often called the silent killer because it usually does not cause symptoms, and people may be unaware that they have it. Mr. Jones' healthcare provider determined that his myocardial infarction (MI) was caused by undiagnosed hypertension. Hypertension forces the heart to pump harder, which puts physical strain on the heart. If left unchecked, hypertension can lead to a heart attack, stroke, or heart failure.
