Heart Health

A Brief Overview of Common Heart Issues | Fullerton, CA

The heart is a remarkably resilient organ, beating over 100,000 times a day to keep the body alive and functioning. Yet heart disease remains one of the leading causes of illness worldwide. Understanding common heart issues can help people recognize risks early and take steps toward prevention and treatment.

One of the most common heart conditions is coronary artery disease (CAD). This occurs when plaque—made up of fat, cholesterol, and other substances—builds up in the arteries that supply blood to the heart. Over time, these narrowed arteries can reduce blood flow, leading to chest pain (angina) or heart attacks. Lifestyle factors such as smoking, poor diet, lack of exercise, and chronic stress significantly increase the risk of CAD.

Heart arrhythmias are another frequent issue. An arrhythmia is an abnormal heart rhythm—too fast, too slow, or irregular. Some arrhythmias are harmless, while others can cause symptoms like palpitations, dizziness, shortness of breath, or fainting. More serious arrhythmias may increase the risk of stroke or sudden cardiac arrest if left untreated.

Heart failure does not mean the heart has stopped working. Instead, it means the heart cannot pump blood efficiently enough to meet the body’s needs. This can result from conditions like high blood pressure, previous heart attacks, or weakened heart muscles. Common symptoms include fatigue, swelling in the legs or ankles, and shortness of breath, especially during physical activity or while lying down.

Another important category is valvular heart disease, which affects the valves that control blood flow through the heart’s chambers. Valves may become stiff, narrow, or leaky, forcing the heart to work harder. Mild cases may cause no symptoms, while severe cases can lead to chest pain, fainting, or heart failure.

Finally, congenital heart defects are structural problems present at birth. These range from minor issues that resolve on their own to complex conditions requiring lifelong care. Advances in medical treatment have greatly improved outcomes for people born with these conditions.

While heart issues vary in severity, many share common risk factors. Maintaining a healthy lifestyle—balanced nutrition, regular exercise, stress management, and routine checkups—plays a crucial role in protecting heart health and catching problems early.
