Aortic stenosis is one such condition that can remain silent for years before causing serious complications. Recognising the warning signs early can help prevent life-threatening outcomes and improve long-term heart health. If you or a loved one notices symptoms that could indicate aortic stenosis, seeking timely evaluation from our cardiologists in Patiala can make a significant difference.
In this guide, you'll learn about the early signs of aortic stenosis, its causes, risk factors, diagnosis, available aortic stenosis treatment options, and when you should seek medical care.
What Is Aortic Stenosis?
Aortic stenosis is a condition in which the aortic valve becomes narrowed, restricting blood flow from the heart to the rest of the body. The aortic valve normally opens fully with each heartbeat, allowing oxygen-rich blood to circulate efficiently. When the valve narrows, the heart must work harder to pump blood.
This condition is also known as aortic valve stenosis and can range from mild to severe. While mild cases may not cause noticeable symptoms, untreated severe aortic stenosis can lead to heart failure, stroke, irregular heart rhythms, or sudden cardiac death.
Why Does Aortic Valve Stenosis Occur?
Several factors can contribute to aortic valve stenosis, including:
- Age-related calcium build-up - The most common cause is calcium deposits accumulating on the aortic valve over time, causing it to stiffen and narrow.
- Congenital heart defects - Some people are born with an abnormal aortic valve, such as a bicuspid valve, increasing the risk of developing aortic stenosis earlier in life.
- Rheumatic fever - Although less common today, rheumatic fever can damage the heart valves and eventually lead to aortic valve stenosis.
- Other risk factors
Your risk increases if you have:
High blood pressure
High cholesterol
Diabetes
Chronic kidney disease
Smoking history
Family history of valve disease
Maintaining a healthy lifestyle and regular heart check-ups can help identify problems before they progress.
Early Aortic Stenosis Symptoms You Should Never Ignore
One of the biggest challenges with aortic stenosis is that symptoms often appear only after the condition has progressed. Paying attention to these warning signs can help you seek treatment before complications develop.
- Chest pain or discomfort - As the narrowed valve limits blood flow, the heart muscle may not receive enough oxygen during physical activity, leading to chest pain or tightness.
- Shortness of breath - Difficulty breathing during exercise, climbing stairs or even routine daily activities may indicate worsening aortic stenosis.
- Fatigue - Feeling unusually tired despite adequate rest is one of the most overlooked aortic stenosis symptoms. Reduced blood flow means your organs and muscles receive less oxygen.
- Dizziness or fainting - If the brain receives insufficient blood supply during exertion, you may feel dizzy or even lose consciousness.
- Heart palpitations - Some people experience irregular or forceful heartbeats as the heart struggles against the narrowed valve.
- Reduced exercise tolerance - If activities you previously enjoyed suddenly become difficult, it should never be ignored.
If you experience any combination of these aortic stenosis symptoms, prompt evaluation is recommended.
