Hjärtförmåga

Hjärtförmåga, also known as cardiac capacity or heart function, refers to the ability of the heart to pump blood effectively to meet the body's metabolic demands. It encompasses several key aspects, including the heart's contractility, its ability to relax and fill with blood (diastolic function), and the efficiency of blood flow through the chambers and valves.

A healthy hjärtförmåga ensures adequate oxygen and nutrient delivery to tissues and organs throughout the body. When hjärtförmåga is compromised, it can lead to various cardiovascular conditions. Reduced contractility, for instance, can result in the heart being unable to pump enough blood, a condition known as heart failure. Impaired diastolic function can hinder the heart's ability to fill properly, leading to elevated pressures within the heart.

Factors influencing hjärtförmåga include genetics, age, lifestyle choices such as diet and exercise, and the presence of underlying health issues like hypertension, coronary artery disease, and valvular heart disease. Medical professionals assess hjärtförmåga through various diagnostic tools, including echocardiography, electrocardiography, and stress tests. Maintaining good cardiovascular health through regular physical activity, a balanced diet, and managing risk factors is crucial for preserving optimal hjärtförmåga.
