Alagebrium in combination with exercise ameliorates age-associated ventricular and vascular stiffness

Advanced glycation end-products (AGEs) initiate cellular inflammation and contribute to cardiovascular disease in the elderly. AGE can be inhibited by Alagebrium (ALT), an AGE cross-link breaker. Moreover, the beneficial effects of exercise on aging are well recognized. Thus, we investigated the eff...

AGE can be inhibited by Alagebrium (ALT), an AGE cross-link breaker. Moreover, the beneficial effects of exercise on aging are well recognized. Thus, we investigated the effects of ALT and exercise (Ex) on cardiovascular function in a rat aging model.

Thus, we investigated the effects of ALT and exercise (Ex) on cardiovascular function in a rat aging model. Compared to young (Y) rats, in sedentary old (O) rats, end-systolic elastance (Ees) decreased (0.9±0.2 vs 1.7±0.4mmHg/μL, P<0.05), dP/dtmax was attenuated (6054±685 vs 9540±939mmHg/s, P<0.05), ventricular compliance (end-diastolic pressure–volume relationship (EDPVR)) was impaired (1.4±0.2 vs 0.5±0.4mmHg/μL, P<0.05) and diastolic relaxation time (tau) was prolonged (21±3 vs 14±2ms, P<0.05). In old rats, combined ALT+Ex (4weeks) increased dP/dtmax and Ees (8945±665 vs 6054±685mmHg/s, and 1.5±0.2 vs 0.9±0.2 respectively, O with ALT+Ex vs O, P<0.05 for both). Diastolic function (exponential power of EDPVR and tau) was also substantially improved by treatment with Alt+Ex in old rats (0.4±0.1 vs 0.9±0.2 and 16±2 vs 21±3ms, respectively, O with ALT+EX vs O, P<0.05 for both). Pulse wave velocity (PWV) was increased in old rats (7.0±0.7 vs 3.8±0.3ms, O vs Y, P<0.01). Both ALT and Ex alone decreased PWV in old rats but the combination decreased PWV to levels observed in young (4.6±0.5 vs 3.8±0.3ms, O with ALT+Ex vs Y, NS). These results suggest that prevention of the formation of new AGEs (with exercise) and breakdown of already formed AGEs (with ALT) may represent a therapeutic strategy for age-related ventricular and vascular stiffness. ► Aging decreases PWV, Ees, dP/dt, ventricular compliance and diastolic relaxation time. ► Exercise or an AGE-breaker alone ameliorate those effects. ► Combining exercise and an AGE-breaker improves those indices comparable to young animals.]]></description><identifier>ISSN: 0531-5565</identifier><identifier>EISSN: 1873-6815</identifier><identifier>DOI: 10.1016/j.exger.2012.04.006</identifier><identifier>PMID: 22569357</identifier><language>eng</language><publisher>England: Elsevier Inc</publisher><subject>Advanced glycation end-products ; AGE ; Aging - physiology ; Alagebrium ; Animals ; Diastole - physiology ; Drug Evaluation, Preclinical - methods ; Exercise ; Glycation End Products, Advanced - antagonists &amp; inhibitors ; Glycation End Products, Advanced - metabolism ; Hemodynamics - physiology ; Male ; Physical Conditioning, Animal - physiology ; Rats ; Rats, Inbred F344 ; Systole - physiology ; Thiazoles - pharmacology ; Vascular Stiffness - drug effects ; Vascular Stiffness - physiology ; Ventricular Function, Left - drug effects ; Ventricular Function, Left - physiology ; Ventricular–vascular coupling</subject><ispartof>Experimental gerontology, 2012-08, Vol.47 (8), p.565-572</ispartof><rights>2012</rights><rights>Copyright © 2012.
