Memorial weekend my husband had his second heart attack in 1 1/2 years. At least 3 weeks before this last attack, we both noticed a definate decrease in his stamina. The same with the first one. Did any of you experience "warning signs" or sublte changes before you heart attacks? I am always watching how I feel because I have CAD and a 100% blocked RCA, fortunately, my heart made new collaterals. Thought it might be interesting to hear stories from others. Thanks in advance.
