Heart Conditioning as a Healthy Strategy in Management of Cardiac Enlargement.

Background: Remote ischemic conditioning (RIC) is widely recognized for its cardioprotective effects in the context of ischemic heart disease. Lately, it has been shown that heart conditioning can be utilized as a healthy strategy in the reversion of disease and aging. In this regard, we examine the impact of RIC on patients with cardiac enlargement.

Methods: Forty-four patients with cardiac enlargement were prospectively enrolled and randomly assigned into RIC group (n = 22) and control group (n = 22). RIC protocol is 3-min inflation/deflation of the blood pressure cuff applied in the upper arm to create transient arm ischemia. RIC treatment was performed once a day for 1 year. Left atrial and ventricular dimensions and left ventricular ejection fraction (LVEF) were all assessed in two groups.

Results: RIC was well-tolerated. After 1 year treatment, left atrial and ventricular dimensions were significantly decreased in the RIC group. Moreover, LVEF showed a significant increase, from 46.24% to 56.45% (P < 0.0001).

Conclusion: The research indicates that a year-long healthy regimen of RIC treatment may effectively reverse cardiac enlargement, thereby endorsing the broader implementation of RIC in the daily routines of these patients.
