What is characterized as a chronic increase in blood pressure?

High blood pressure, also known as hypertension, is characterized as a chronic increase in blood pressure. This condition occurs when the force of the blood against the walls of the arteries is consistently too high, leading to potential damage to the heart and blood vessels over time. Blood pressure is typically measured in millimeters of mercury (mmHg) and is expressed with two numbers, systolic (the pressure during heartbeats) over diastolic (the pressure when the heart is at rest).

Hypertension can result from a variety of factors, including obesity, high salt intake, lack of physical activity, and genetics. The condition often develops without symptoms, which is why it’s sometimes referred to as a "silent killer." Long-term effects of untreated high blood pressure can include serious health issues such as heart disease, stroke, and kidney damage.

Understanding the chronic nature of high blood pressure highlights its importance in medical practice. Unlike acute conditions that have a rapid onset, hypertension requires ongoing management and lifestyle changes to control and prevent complications. This makes it distinct from other options listed, which pertain to different cardiovascular or systemic issues that do not specifically denote sustained high blood pressure.
