1. Mechanism of action of calcium-channel-blocking agents;Braunwald, E.;N Engl J Med,1982
2. Verangina and improved myocardial metabolism.'6 This apamil in chronic stable angina. Lancet 1980; i: 841-4. would suggest that the antianginal effect is not due to increased coronary blood flow. In animal studies, however, under conditions simulating unstable angina;Balasubramanian, V.; Paramasivan, R.; Lahiri, A.; Raftery, E.B.
3. Objective assessment of antianginal treatment: a double-blind comparison of propranolol, nifedipine and their combination;Lynch, P.; Dargie, H.; Krikler, S.; Krikler, D.;Br Med J,1980
4. Effect of dilby increasing collateral flow. During pacing diltiazem reduced left ventricular afterload and rate pressure product. This might be expected to reduce myocardial oxygen consumption, tiazem on pacing-induced ischemia in conscious dogs with coronary stenosis: improvement of postpacing deterioration of ischemic myocardial function;Sasayama, S.; Takahashi, M.; Nakamura, M.;Am J Cardiol,1981
5. Differential cardiovascular effects of calcium channel as rate pressure product during pacing induced blocking agents: potential mechanisms;Millard, R.W.; Lathrop, D.A.; Grupp, G.; Ashraf, M.; Grupp, I.L.; Schwartz, A.;Am J Cardiol; 49: tachycardia is a good indicator of the level of myocardial oxygen demand.'8 Surprisingly, in this study we failed to show a significant reduction in myocardial 499-506,1982
