Hello, Your doctor uses blood pressure readings obtained from a treadmill test to find evidence of coronary artery blockage. Your BP reading of 160/90 at the end of TMT test is normal. Under normal circumstances, you can expect systolic blood pressure to increase to about 200 at the peak of the test and diastolic blood pressure to remain steady or fall only slightly. A stress test will usually be terminated if any signs or symptoms such as ECG changes or chest pain appear. Blood pressure responses that will end a test include a drop in systolic blood pressure that is greater than 10 mm Hg after an increase in work intensity, a systolic blood pressure greater than 250 mm Hg,or a systolic blood pressure that fails to rise to greater than 140 mm Hg at peak, or a diastolic blood pressure greater than 115 mm Hg. Cortical cysts are generally benign,filled with fluid and generally detected in ultrasound. It needs only monitoring and no intervention is required.In case these cysts become bigger or get infected or if they turn malignant,only then surgical intervention is required. Your reports are normal and there is nothing to worry. Thanks
