A history of childhood asthma correlates with high left ventricular mass, a prominent indicator of cardiac damage, in asymptomatic healthy young adults, according to a report published online June 26 in JACC: Heart Failure.
“Our data suggest that aggressive lifestyle modifications or even pharmacologic treatment may be applied to people with a [childhood] history of asthma. … to lower cardiovascular risk,” said Dianjianyi Sun, MD, PhD, of the department of epidemiology, Tulane University, New Orleans, and his associates.
Both mean left ventricular mass (169 g) and mean left ventricular mass index (41 g/m2) were significantly higher in participants who’d had childhood asthma than in those who had not (158 g and 38 g/m2, respectively). This correlation was independent of major cardiovascular risk factors such as race, smoking status, hypertension status, use of antihypertensive medications, C-reactive protein levels, heart rate, and body mass index, the investigators said (JACC: Heart Failure. 2017 Jun 26. doi: 10.1016/j.jchf.2017.03.009).
The association was strongest among young adults who had higher systolic blood pressure (prehypertension or hypertension).

Sun et al. report that healthy young adults who had asthma during childhood have a significantly greater left ventricular mass index, by about 8%, than do those who didn’t have the condition.
On an individual patient level, such a difference confers a relatively small incremental risk of incident cardiovascular disease: a roughly 1.08-fold increase. However, at the population level, where there are many major comorbidities, the public health implications could be substantial. Targeting these patients for intensified cardiovascular risk reduction could have important benefits.

FROM JACC: HEART FAILURE
Key clinical point: Childhood asthma is associated with high left ventricular mass in asymptomatic young adults.
Major finding: Both mean left ventricular mass (169 g) and mean left ventricular mass index (41 g/m2) were significantly higher in participants who’d had childhood asthma than in those who had not (158 g and 38 g/m2, respectively).
Data source: A secondary analysis of data from the Bogalusa Heart Study, involving 1,118 participants followed for an average of 10 years.
