Systolic pressure is the top number in a blood pressure reading, representing the force of blood against the artery walls when the heart beats. It indicates how much pressure is exerted when the heart pumps blood into the arteries. A normal systolic pressure is typically around 120 mmHg, but it can vary based on factors like age, activity level, and overall health. High systolic pressure, often referred to as hypertension, can lead to serious health issues, including heart disease and stroke. Monitoring systolic pressure is essential for maintaining good cardiovascular health, and regular check-ups with a healthcare provider can help manage and prevent potential problems.
