What is Aortic Stenosis ?
Aortic valve stenosis is a type of heart valve disease where the aortic valve narrows and doesn’t open fully, limiting blood flow from the heart to the aorta and the rest of the body.
Symptoms of Aortic Stenosis
- 1. Chest pain or tightness (angina)
- 2. Shortness of breath, especially during physical activity
- 3. Fatigue or feeling unusually tired
- 4. Heart palpitations or irregular heartbeats
- 5. Dizziness or lightheadedness, particularly when standing up
- 6. Swelling in the ankles, feet, or legs
- 7. Fainting or near-fainting episodes, especially during exertion
The Impact and Complications of Aortic Stenosis
The main impact of aortic stenosis is a reduction in blood flow from the heart to the rest of the body, which can cause significant strain on the heart. Over time, this can lead to heart failure, as the heart struggles to pump blood efficiently. The hidden impact often includes gradual damage to other organs due to reduced blood supply, as well as the risk of arrhythmias, stroke, or sudden cardiac arrest. If left untreated, aortic stenosis can lead to severe complications, significantly affecting a person's overall health and quality of life.

Importance and Benefits of Consulting a Cardiologist Online
Early consultation with a cardiologist is essential for the effective management of aortic stenosis. This condition is more prevalent in older adults, particularly in developed countries with aging populations. It is especially common in nations like the United States, Canada, and many European countries, where the incidence of heart valve diseases rises with age. However, aortic stenosis can affect individuals globally, with growing awareness and diagnosis in both developed and developing countries.

FAQ
Aortic stenosis can result from several factors. In older adults, the most common cause is age-related calcification, where calcium deposits accumulate on the aortic valve, causing it to stiffen and narrow. It can also stem from congenital heart defects, such as a bicuspid aortic valve, which increases the likelihood of valve narrowing over time. Rheumatic fever, a complication of untreated strep throat infections, can damage the aortic valve, leading to stenosis later in life. Additionally, chronic conditions like high blood pressure and high cholesterol can contribute to the thickening and hardening of the valve, increasing the risk of aortic stenosis.
Aortic stenosis can lead to several serious complications if left untreated. The most significant risk is heart failure, as the heart struggles to pump blood effectively due to the narrowed valve. This can lead to fluid buildup in the lungs and other organs. Aortic stenosis also increases the risk of arrhythmias, which are irregular heartbeats that can lead to sudden cardiac arrest. Other potential complications include stroke, as the restricted blood flow can cause blood clots to form, and fainting, especially during physical exertion. In severe cases, untreated aortic stenosis can be fatal. Early detection and treatment are crucial to managing these risks.
Aortic stenosis can be hereditary, especially when associated with a congenital heart defect. Some people are born with a bicuspid aortic valve instead of the normal tricuspid valve, which raises the likelihood of developing aortic stenosis later in life. While not all instances of aortic stenosis are genetic, a family history of heart valve disease can increase the risk. Therefore, individuals with a family history of the condition should be regularly monitored by a healthcare professional to detect early signs and manage potential risks.
Aortic stenosis cannot always be prevented, especially if it is congenital or age-related. However, managing risk factors like high blood pressure, high cholesterol, and diabetes can help reduce strain on the heart. Maintaining a heart-healthy lifestyle through a balanced diet, regular exercise, and avoiding smoking is crucial. Regular check-ups are important for early detection, particularly for those with a family history or existing valve conditions. Treating infections, such as endocarditis, and monitoring existing conditions, like a bicuspid aortic valve, can also help prevent further damage to the heart valves.
