<s>[INST] I am a 61 year old male taking Crestor for high cholesterol. Recently had a heart scan with a score of 700. An irregular heart beat is believed to be from birth. I am experiencing pin prick sensations in the left chest area. Are these sensations heart related?I also have a high level of fatigue and low blood pressure. [/INST] Dear; thanks for using our service.Crestor is a save drug and is has been found to improve mortality in patients with hyperlipidemia and coronary artery disease.

It is good that you had an excellent results in the heart scan, but regular electrocardiogram and possible stress test is indicated.I hope that my advise has been helpfulDr.Sara </s>
