It is found that there is a statistical link between asthma and heart disease, although doctors have yet to hammer out a clear-cut connection between them.

Doctors and medical researchers have a various theories about the probable link between heart disease and asthma such as:

  1. The gene theory

    There are 29 genes known to be associated with asthma and it is considered to be one of those genes responsible for it.

  2. The weight factor 

    Obesity certainly contributes to developing asthma and to developing heart disease.

  3. The inflammation dilemma

    Heart disease is an inflammatory disease, as that’s what leads to toughening of the arteries. Similarly, asthma is caused by inflammation of the airway.

Is Asthma medication the culprit?

Asthma medication also poses a big question mark regarding the link between heart disease and asthma. For instance, beta-agonists, which are used to treat asthma, are quick-release drugs that also stimulate the heart. They also lower the potassium level in the blood, which can lead to disturbances in heart rhythm. It has long been thought that they may increase the chance of a cardiac event, though there have been findings that led to no solid link. Similarly, elevated dosage of corticosteroids, which are used to treat asthma have been linked with atrial fibrillation, a heart condition in which the upper chambers of the heart quiver instead of beating normally. Hence, excessive use of beta-agonists over a short period of minutes or hours could have a hazardous effect on the heart.

The study says so

A medical study involving more than 15,000 women and men found a link between adult onset of asthma and heart disease in women. Researchers compared the risk of coronary heart disease or stroke in people with childhood-onset asthma to those with adult-onset asthma and found that women suffering with adult-onset asthma have twice the risk for coronary heart disease and stroke, even after adjusting data for known heart disease risk factors such as age, body mass index, smoking frequency and a lack of exercise.

Another study found that exposure to even small amounts of coarse particles in the air, such as construction dust and other particulate matter, raised bad cholesterol levels and increased coronary risk factors for heart problems in people already suffering with asthma.

Considering the link between these two conditions, consult your doctor about managing asthma symptoms along with various ways to maintain or even boost your cardiovascular health.
