I can understand your concern. Rancad and scorecard, both are anti-anginal Chat Doctor. Your TMT is positive, and you are having chronic chest pain. So possibility of coronary artery disease CAD is more in your case. So better to get done coronary angiography to identify the blockage and angioplasty to relieve the blockage. This is a ideal way of managing anginal chest pain. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
