Abstract:

Objective To compare the clinical characteristics and risk factors of hypertension with silentmyocardial infarction（HTN⁃SIM）. Methods 51 consecutive patients with HTN⁃SIM who were addressed in ourhospital from February 2016 to February 2019 were selected continuously，and 140 patients with hypertension（HTN）were selected during the same period. Their clinical characteristics were compared and their risk factorswere analyzed. Results Compared with HTN group，HTN⁃SIM group were older and had a longer course of hyper⁃tension. Compared with HTN group，HTN⁃SIM group had more dizziness，more dyspnea ，more oral ACEI/ARBdrug history，more coronary heart disease，and more hyperuricemia. Logistic regression analysis showed that thelong course of hypertension（OR = 1.092）and the history of coronary heart disease（OR = 3.107）was independentrisk factors for HTN⁃SIM. Conclusion Old age，long course of hypertension，and coexisting diseases are the clinicalfeatures of HTN⁃SIM. Dizziness and dyspnea are common clinical symptoms of HTN⁃SIM. In addition，we alsofound that the long course of hypertension and history of coronary heart disease are independent risk factors for thedevelopment of hypertension intoHTN⁃SIM.
