  • Title: Significance of exercise induced increase in the diastolic pressure as an indicator of severe coronary artery disease.
    Author: Chatterjee S, Kumar S, Shetty DP, Panja M.
    Journal: J Indian Med Assoc; 1996 Dec; 94(12):443-4, 451. PubMed ID: 9141850.
    Abstract:
    A total of 100 patients were studied for the diastolic blood pressure response to treadmill exercise testing. No change in the diastolic pressure or lowering of the pressure was considered normal response. Seventy-four patients had normal and 26 patients had abnormal diastolic blood pressure response. Forty patients underwent coronary angiography. Fifty-five per cent of the patients with normal diastolic pressure response had normal coronaries compared to 20% with abnormal response. Eleven per cent with normal response and 40% with an abnormal response had triple vessel disease whereas 10% with abnormal response had left main coronary artery disease. Exercise induced ST segment depression was almost equal in both groups. Hence it can be concluded that abnormal diastolic pressure response to treadmill exercise testing is a fairly good indicator of coronary artery disease irrespective of ST segment changes.
