There is evidence that suggests that high altitudes increase the risk of heart attacks, especially in individuals who are not acclimated to such conditions. At higher altitudes, the air pressure and oxygen level are low, which leads to lower oxygen saturation in the blood. This reduction in oxygen availability can put strain on the cardiovascular system, particularly in individuals with pre-existing heart conditions.

In this blog, Dr. Sujay Shad, the best cardiac surgeon in India, has shared the association between high altitudes and heart diseases. Continue reading for further information.

Factors that Increase the Risk of Heart Conditions at High Altitudes
1. Reduced Oxygen Level: Higher altitudes can result in lower blood oxygen saturation, which can put strain on the heart and aggravate pre-existing cardiovascular conditions.

2. Increased Heart Rate: The heart may beat faster to make up for the lower oxygen levels and deliver more oxygen to the body's tissues. This increased heart rate can be problematic for individuals with heart issues.

3. Formation of Blood Clot: Blood clotting can be increased due to high altitude. This happens due to factors such as an increased level of red blood cells and platelets, which increase the risk of clot formation.

4. Fluid Retention: Some individuals might experience fluid retention at a higher altitude, which worsens heart conditions and increases the risk of heart attack.

5. Cold Weather: Many high-altitude environments are extremely cold, and cold weather can constrict blood vessels, potentially increasing blood pressure and stressing the cardiovascular system.

Heart Conditions that One Needs to Look Out For
One should make appropriate plans while traveling to high altitudes, depending on the patient's pre-existing illnesses and general health. Here are some of the conditions one needs to plan for:

1. Heart Failure: A trip at a high altitude brings difficulties for those who have chances of heart failure. It also increases blood levels of stress hormones, which are otherwise high due to chances of heart failure. The blood pressure may excessively increase if one is producing more stress hormones. However, as long as their health is stable, they have adequate left ventricular function, and they have the ability to exercise, they can still travel to high altitudes.

2. High Blood Pressure: One should try and manage their blood pressure before going because it tends to rise at higher altitudes. Discuss with a heart specialist to change the medications if the blood pressure increases.

3. A Congenital Heart Disease: High altitudes can be problematic for people with heart diseases that result in irregular blood flow from the right side of the heart to the left.

Conclusion
It is worth noting that individuals who are acclimated to high altitudes, such as those who live there or have spent time gradually adjusting to the conditions, may have a reduced risk of cardiovascular events compared to those who are not accustomed to such environments. If one has pre-existing heart conditions or is worried due to the potential risks of being at high altitude, it is best to consult an expert heart doctor in Delhi, one like Dr. Sujay Shad, before planning.
