Asthma during childhood and adolescent years linked to heart problems

Asthmatic teenagers likely to suffer from heart problems later

If your teenage kid is suffering from asthma, you better be careful about his/ her future. A recent study has indicated that young adults with a history of asthma are at a greater risk of developing heart failure.

In a first study that links childhood asthma with cardiac condition, known as left ventricular hypertrophy, in adulthood, the common respiratory disease was found to lead to a thickening of the left ventricle, which can cause the heart muscle to lose elasticity and eventually fail to pump. The research, published in JACC: Heart Failure, examined 1,118 patients who answered a questionnaire on their asthma history.

Left Ventricular Hypertrophy (LVH) can cause shortness of breath, chest pain and fainting. Thickening of the heart’s left ventricle (tissue in the bottom right-hand corner of the organ) can cause shortness of breath, chest pain, fainting, and may eventually lead to heart failure.

When these patients were examined after a decade, the ones suffering with asthma had a higher left ventricular mass compared to the ones without. Researchers discovered that the link was stronger in patients with high and raised blood pressure. As you must be aware that the right and left sides of your heart do different jobs. Because the left side of the heart needs to work harder to get blood round the body, it is usually this side that becomes enlarged when your blood pressure is too high or you have a health condition that causes the heart to work harder than normal.

Women, exposed to polluted air and stressful situations during their pregnancy, are more likely to give birth to children with asthma. Boys whose mothers were exposed to both risk factors were more likely to develop the condition by age six. The study, conducted by Icahn School of Medicine at Mount Sinai, looked at more than 700 primarily African-American and Latina pregnant women living in urban areas.
