###Human: Will having 130 bpm during exercise increase the risk of stroke in heart patient? ###Assistant: Hello. Firstly, answering your queries, you should visit a cardiologist regularly and avoid strenuous activities in order to reduce the risk of acute coronary syndrome. Your echo has some abnormalities which are age-related and there is no evidence of CAD. However, calcium score is elevated which implies there is a significant risk of coronary artery disease, which is probably in earlier stages as you do not get any symptoms on the treadmill. However, such minor plaques may rupture and give rise to ACS. So, you should avoid strenuous activity and should be on both antiplatelet like Aspirin and statins. Also, you should undergo a stress test like either stress thallium or stress echo or treadmill test.
