About 1088212 hypertensive patients who received their first prescription for antihypertensive therapy between January 2021 to June 2021, were obtained from a database of Hangzhou Kang Sheng Health Consulting CO., Ltd. Calcium channel blockers (CCBs) and angiotensin II receptor blockers (ARBs) were the most common drugs prescribed for each comorbidity subgroup. Whereas diabetes mellitus or renal disease is a compelling indication for use of renin-angiotensin system inhibitors, CCBs were often administered in these subgroups. The treatment pattern for patients with coronary heart disease was closely similar to that for the overall patient population. Beta-blockers (BBs) were prescribed more frequently for patients with heart failure than for those with other comorbidities. Although antihypertensive drug prescription varied by comorbidity, pharmacological decisions were largely made under Chinese recommendations while physicians could select antihypertensive drugs based on the patients' comorbidities.
