CORRECT ANSWER - -Lower
-Stent (25% failure rate)
-PTCA (30-50%)
Beta blockers effect on exercise - CORRECT ANSWER - -Anginal threshold by reducing
myocardial oxygen demand
-BP also reduced by reduction in CO
-Reduction in total peripheral resistance

ECG monitoring after exercise - CORRECT ANSWER - -Immediately, then every 1-2 min
for 5 min of recovery or until exercise-induced changes are at a baseline
