No: A combination with aerobic and anaerobic excessive is good for you. Muscle mass will increase your metabolic rate. You need to consult your physician before and avoid drugs to enhance muscle mass like anabolic steroids. I personally weight lift 45 minutes 4 times a week.

Not usually: Unless a person has under treated hypertension or existing heart disease. The straining associated with lifting weights transiently increases blood pressure and cardiac afterload. In a stressed heart that is already thickened by hbp the afterload increase can weaken the heart further. Getting a medical exam first is appropriate and highly advised.
