Can negative cardiac effect of proton pump inhibitor and high-dose H2-blocker have clinical influence on patients with stable angina?

Summary Background Aspirin and anti-platelet drugs are used commonly for patients with coronary heart disease. Proton pump inhibitor (PPI) and high-dose H2-blocker were recommended for preventing NSAIDs-related ulcer. Previously H2-blocker reported to have some negative cardiovascular effects. Addit...

Description
Summary:Summary Background Aspirin and anti-platelet drugs are used commonly for patients with coronary heart disease. Proton pump inhibitor (PPI) and high-dose H2-blocker were recommended for preventing NSAIDs-related ulcer. Previously H2-blocker reported to have some negative cardiovascular effects. Additionally, a recent in vitro study showed that PPI reduced cardiac contractility. In this study, we evaluated whether chronic administration of PPI and high-dose H2-blocker affects left ventricular function. Method Fifty-two stable angina patients were enrolled and classified into PPI group ([P]; lansoprazole: 15 mg/day, n = 28), H2-blocker group ([H]; famotidine: 40 mg/day, n = 8), and control ([C]; none or mucosal-defense drug, n = 16). Eligible patients showed normal cardiac function in initial catheterization without administrated PPI or H2-blocker. They received percutaneous coronary intervention and follow-up catheterization. We compared changes in ejection fraction (EF: %), end diastolic/systolic volume index (EDVI/ESVI: ml/m2 ), and peak positive/negative d p /d t (±d p /d t : mmHg/s) in left ventricular angiography series. Result There were no significant differences among three groups regarding patient characteristics, backgrounds of angiographic and intervention, except for fewer smokers in [C]. Other drugs such as β- and Ca-blocker did not have effects on cardiac function except for aspirin during 255 ± 115 days follow-up. Rate of EF changes significantly decreased in [P], and tended to decrease in [H] (C: 3.8 ± 9.8%, H: −1.6 ± 7.6%, P: −2.1 ± 5.9%; p < 0.05 for [C] vs. [P]). Those of ESVI changes were significantly greater in [P], and tended to be greater in [H] (C: −4.5 ± 16.2%, H: 4.9 ± 15.5%, P: 7.3 ± 16.2%; p < 0.05 for [C] vs. [P]), though, EDVI changes’ were similar (C: 2.5 ± 8.9%, H: 2.6 ± 3.6%, P: 1.6 ± 6.1%; p = ns). Rate of ±d p /d t —changes tended to decrease in [H] (+d p /d t : C: 3.9 ± 15.5%, H: −10.0 ± 25.2%, P: 0.3 ± 19.6%; p = ns, −d p /d t : C: −0.1 ± 19.5%, H: −8.5 ± 20.4%, P: 5.7 ± 27.7%; p = ns). Conclusion In this study, PPI and high-dose H2-blocker have EF-reducing tendency. However, these changes were small and these drugs seemed to exhibit little influence clinically.
