Is Heart Valve Disease Straining Your Heart?

Your heart works hard every second of the day, but what if a faulty valve is making it work overtime? Heart valve disease can quietly strain your heart, turning every beat into a struggle. Heart valve disease affects the heart's ability to pump blood efficiently. While often asymptomatic in its early stages, it can lead to significant health complications if left untreated. In India, heart valve disease is a growing concern, particularly due to changing lifestyles and increasing rates of cardiovascular diseases. Understanding the causes, symptoms, and treatment options for this condition is crucial for maintaining optimal heart health.

What is heart valve disease?

Your heart tirelessly pumps blood throughout your body. At the heart of this process are four small yet essential valves: the aortic, mitral, pulmonary, and tricuspid valves. They control blood flow between the heart's chambers, making sure circulation runs smoothly. Heart valve disease refers to a condition where one or more of the heart’s valves do not function properly. Rheumatic aortic stenosis, a condition that affects these valves, is most common in Asia, with India reporting a prevalence of 4.54%.

How do heart valves keep your blood flowing?

The four heart valves function as one-way valves, moving blood while preventing backflow into one of the heart's four chambers. When the heart beats (contracts), the valves open and close alternately, pumping blood through the two atria (upper chambers) and two ventricles (lower chambers). There are four types of heart valves:

• Tricuspid valve: Located between the right atrium and right ventricle.

• Pulmonary valve: Between the right ventricle and the pulmonary artery.

• Mitral valve: Between the left atrium and the left ventricle.

• Aortic valve: Between the left ventricle and the aorta.

What are the types of heart valve disease?

Heart valve disease occurs when one or more of the heart's four valves malfunctions. There are four primary types of heart valve disease:

1. Aortic stenosis

This disorder occurs when the aortic valve narrows, preventing blood from flowing from the heart's left ventricle to the aorta. As a result, the heart has to work harder to pump blood, which causes symptoms such as shortness of breath, chest pain, and exhaustion.

2. Aortic regurgitation

Aortic regurgitation occurs when the aortic valve does not seal securely. This allows blood to seep backwards from the aorta and into the left ventricle. Over time, this can put a strain on the heart, causing symptoms such as shortness of breath, exhaustion, and palpitations. It has been found that the incidence of isolated aortic valve disease, particularly isolated aortic stenosis, is lower in the Indian population. 

3. Mitral stenosis

Mitral stenosis occurs when the mitral valve narrows, preventing blood flow from the left atrium into the left ventricle. This can cause the left atrium to expand, resulting in symptoms such as shortness of breath, exhaustion, and irregular pulse.

4. Mitral regurgitation

Mitral regurgitation occurs when the mitral valve fails to shut properly, causing blood to seep backward from the left ventricle into the left atrium. This can overwhelm the heart, resulting in symptoms such as shortness of breath, exhaustion, and palpitations.

The silent symptoms of heart valve disease

It's worth noting that many people with early-stage heart valve disease may have no symptoms. As the illness progresses, symptoms may worsen. If you encounter these symptoms, you should speak with a healthcare expert for a correct diagnosis and treatment. While heart valve disease often progresses silently, several symptoms may indicate an underlying issue:

Common symptoms:

• Shortness of breath: Difficulty breathing, especially during physical activity.

• Fatigue: Feeling tired and weak, even after minimal exertion.

• Chest pain or discomfort: A squeezing or tightness in the chest.

• Swelling in the legs, ankles, or feet: Fluid buildup due to poor heart function.

• Palpitations: Feeling a rapid or irregular heartbeat.

   Less common symptoms:

• Cough, especially at night: A dry cough caused by fluid buildup in the lungs.

• Fainting: A sudden loss of consciousness due to reduced blood flow to the brain.

What causes heart valves to malfunction? 

Genetic predispositions, age-related wear and tear, infections, and underlying medical disorders are all potential causes of heart valve dysfunction. While it is more frequent in older adults, younger people, particularly men, can also be impacted, especially if they have genetic risk factors or lifestyle practices that make them more susceptible. 

For example, disorders such as Marfan syndrome and bicuspid aortic valve might predispose people to heart valve difficulties, which commonly appear at a young age. Furthermore, lifestyle factors, including smoking, high blood pressure, and excessive cholesterol, might hasten the progression of heart valve disease.

Steps to a healthy heart: Reducing valve disease risk

While you can't always control your genetic predisposition, there are several lifestyle factors you can modify to reduce your risk of heart valve disease:

1. Healthy lifestyle habits 

Consuming a diet rich in fruits, vegetables, whole grains, and lean proteins while limiting your intake of saturated and trans fats, cholesterol, and sodium can help to keep your heart healthy.  Engaging in regular physical activity, such as brisk walking, swimming, or cycling, also protects the heart. Being overweight or obese can increase your risk of heart disease. Smoking damages blood vessels and increases the risk of heart disease. Excessive alcohol intake can harm your heart.

2. Regular health check-ups

High blood pressure can strain the heart and contribute to heart valve disease. High cholesterol levels can lead to plaque buildup in the arteries, affecting the overall heart function. Dental infections can spread to the heart and damage the heart valves. Conditions like diabetes, high blood pressure, and high cholesterol should be managed early and effectively to reduce the risk of heart valve disease.

Heart valve disease might be stealing your spark

Your heart's a constant worker, and it deserves some love! Heart valve disease might sound scary, but by understanding the basics and making smart choices, you can keep your ticker ticking smoothly.

Remember, a balanced diet, regular exercise, and regular check-ups are your heart's best friends. If you notice any unusual symptoms, don't hesitate to consult a doctor. Early detection and treatment can make a world of difference.

Frequently Asked Questions:

1. What causes damage to heart valves? 

Heart valves can be damaged by various factors, including congenital heart defects, infections, age-related wear and tear, and underlying medical conditions like rheumatic fever and connective tissue disorders.

2. What is the most common heart valve disorder? 

Aortic stenosis is one of the most common heart valve disorders, affecting millions of people worldwide. It occurs when the aortic valve narrows, restricting blood flow from the heart to the body.

3. Can heart valve problems go away? 

In most cases, heart valve problems do not go away on their own. However, early diagnosis and appropriate treatment, such as medication or surgery, can help manage the condition and improve the quality of life.

4. What exercise is good for heart valve disease? 

Low-impact exercises like walking, swimming, and cycling are generally recommended for people with heart valve disease. It's essential to consult with a healthcare provider to determine the best exercise regimen.

5. Does walking help heart valves? 

Yes, walking can be beneficial for people with heart valve disease. It helps improve cardiovascular health, strengthens the heart muscle, and can aid in weight management. However, it's important to consult with a healthcare provider to determine the appropriate intensity and duration of walking.
