I51: Complications and ill-defined descriptions of heart disease

Complications and ill-defined descriptions of heart disease cover a wide range of conditions that affect the heart, which is the body's main organ responsible for circulating blood. These conditions may result from damage to part of the heart, a disorder of the heart rhythm, or a decrease in the body's ability to pump blood effectively. Symptoms vary widely depending on the specific heart condition but can include chest pain, shortness of breath, dizziness, and fatigue. In some cases, individuals may experience few or no symptoms at all. The progression of these conditions may be gradual, with health gradually worsening over time, or can occur suddenly, resulting from an acute event such as a heart attack. These conditions are not transmitted from person to person but may be influenced by factors such as age, family history, lifestyle choices, or the presence of other health conditions.
