Angiotensin converting enzyme inhibitors have a good effects for patients with primary hypertension and in solving some outcomes of the diseases leading to left ventricular insuffiency. The mechanism of the drugs is to bind zinc ion of angiotension converting enzyme. Therefore, the effect of converting angiotensin I into angiotension II was lost. Angiotension II has effect of the smooth muscle stimulation, aldosterone excretion, hemodynamic change, catecholomine release and glucocorticoid exeretion.

INTRODUCTION: The pandemic caused by coronavirus disease 2019 (COVID-19) posed a serious challenge to all health care systems in the world. It has been found to be harmful in people with underlying cardiovascular diseases, particularly in patients with systemic hypertension, which may be due to upregulation of angiotensin-converting enzyme 2 (ACE2) expression, which may lead to increased severe acute respiratory syndrome coronavirus 2 virulence. Renin-angiotensin system inhibitor (RASI) acts by blocking the angiotensin-converting enzyme and angiotensin II type 1 receptors, which in turn affects the production of the ACE2 protein. Hence, there have been arguments on whether to continue or discontinue this medication. Given the widespread use of RASIs globally and the fact that they are generally cardioprotective, research into the safety of continuing these maintenance medications in patients hospitalized with mild to moderate COVID-19 is immensely needed. METHODS: This meta-analysis involved review of observational studies among hypertensive patients on maintenance ACE inhibitor or angiotensin-receptor blocker with confirmed mild to moderate COVID-19 infection. Analyses were performed to determine the adjusted hazard ratio of each event using the raw data obtained from each study. Random-effects model and Cochran-Mantel-Haenszel method were utilized at 95% confidence interval. To check for heterogeneity, χ2 test and I2 statistic were calculated. Cochrane ReviewManager (RevMan version 5.3) was used for data analysis, and forest plots were generated. RESULTS: At 95% confidence interval, the adjusted hazard ratios for all-cause mortality and intensive care unit (ICU) admission at 95% confidence interval were 1.64 (1.22, 2.21) and 1.93 (1.34, 2.79), respectively. The tests of overall estimate effect for both outcomes were P < 0.0001 for all-cause mortality and P = 0.0003 for ICU admission. CONCLUSION Discontinuation of maintenance RASI during hospitalization is associated with increased all-cause mortality and ICU admission among hypertensive patients with mild to moderate COVID-19 infection.

Introduction: The incidence of angiotensin-converting enzyme inhibitors (ACEi)-induced cough has been reported between 5% and 30% but is unknown in Malaysia. This study aimed to determine the incidence of ACEi-induced cough and its associated factors in a public primary care clinic in Malaysia. Methods: A retrospective review of electronic medical records of patients who were initiated ACEi between January 1, 2015, and December 31, 2015, and reviewed until July 31, 2016. A total of 1,091 patients were newly prescribed ACEi, and 394 patients were eligible for this study. We excluded patients who defaulted follow-ups with no further clinic visits before July 31, 2016, were transferred to the clinic without the recorded date of ACEi initiation, were transferred to other clinics during the study period, were followed up at other clinics and attended the study clinic for a short period, or were given only a stat dose of ACEi. Results: Among the 394 patients initiated on ACEi, 225 (57.1%) were male, 369 (93.7%) were Malay, 376 (95.4%) had hypertension, and 192 (48.7%) had diabetes. The incidence of ACEi-induced cough was 24.1%, and 42 (10.7%) patients developed cough on the day of therapy initiation. There was no association between age, gender, ethnicity, type of ACEi, and cough. Conclusion Approximately one quarter of patients developed cough after ACEi initiation, and approximately half of them developed cough within 1 week of ACEi initiation. Doctors should consider early follow-up for patients initiated on ACEi therapy to ensure adherence, quality of life, and minimise unnecessary treatment.

To evaluate the efficacy and safety of Songling Xuemaikang Capsules combined with conventional Western medicine in the treatment of essential hypertension. PubMed, VIP, CNKI, Wanfang and other databases were retrieved from the establishment of the database to February 2020 for clinical randomized controlled trial(RCT) about Songling Xuemaikang Capsules combined with conventional Western medicine in the treatment of essential hypertension. The literatures were screened out according to the inclusion criteria, and RevMan 5.3 software was used for Meta-analysis. A total of 3 100 patients in 27 RCTs were enrolled. According to Meta-analysis, Songling Xuemaikang Capsules combined with conventional Western medicine could effectively reduce systolic blood pressure(MD=-7.88,95%CI[-9.68,-6.08],P<0.000 01) and diastolic blood pressure(MD=-7.85, 95%CI[-9.07,-6.62], P<0.000 01), triglyceride(MD=-0.46, 95%CI[-0.66,-0.26], P<0.000 01) and total cholesterol(MD=-0.92, 95%CI[-1.49,-0.35], P=0.001), but increase HDL cholesterol(MD=0.51, 95%CI[0.28, 0.73], P<0.000 01), with a better effect than the Western medicine group alone. The results of LDL-C analysis showed that there was no significant difference between the two groups(MD=-0.91, 95%CI[-1.82, 0.01], P=0.05). The subgroup analysis suggested that reduced systolic blood pressure may be related to the use of ARB. There was a close correlation between CCB drugs and the decrease of diastolic blood pressure. In addition, there was no significant difference in the compliance and the incidence of adverse reactions. Clinical application of Songling Xuemaikang Capsules combined with Western medicine in the treatment of patients with essential hypertension has clear efficacy and certain safety. More clinical randomized controlled trials are needed for verification in the future.

BACKGROUND: Activation of renin-angiotensin system (RAS) has been an important mechanism of microvascular and macrovascular complications in diabetic patients. It has been reported that RAS blockades reduce the development and progression of diabetic nephropathy. The aim of this study was to evaluate whether valsartan, an angiotensin II receptor blocker (ARB), reduced blood pressure and urinary albumin excretion rate (UAER) in hypertensive type 2 diabetic patients. METHOD: Three hundred forty-seven hypertensive type 2 diabetic patients who had not taken angiotensin converting enzyme inhibitors or ARB for 6 months prior to this study were enrolled. We measured blood pressure and UAER before and after 24 weeks of valsartan treatment. RESULT: Baseline mean systolic and diastolic blood pressure was 143 +/- 15 and 87 +/- 11 mmHg, respectively and the median albumin excretion rate was 27 ug/mg. Reduction in systolic and diastolic blood pressure was 16 mmHg/10 mmHg and the median UAER was 19.3 ug/mg after 24 weeks (P < 0.01, respectively). When we divided the subjects into three groups according to the UAER (normoalbuminuria, microalbuminuria and macroalbuminuria), significant changes were reported in the microalbuminuria and the macroalbuminuria groups. Thirty-eight (42%) patients with microalbuminuria improved to normoalbuminuria and twelve (41%) patients with macroalbuminuria improved to microalbuminuria. We found an association between the improvement of blood pressure and UAER (R = 0.165, P = 0.015). CONCLUSION: We concluded that valsartan reduces urinary albumin excretion and blood pressure in hypertensive type 2 diabetic patients.

OBJECTIVE: Chronic subdural hematoma (cSDH) is common condition in neurosurgical field. It is difficult to select the treatment modality between the surgical method and the conservative method when patients have no or mild symptoms. The purpose of this study is to provide a suggestion that the patients could be cured with conservative treatment modality. METHODS: We enrolled 16 patients who had received conservative treatment for cSDH without special medications which could affect hematoma resolution such as mannitol, steroids, tranexamic acid and angiotensin converting enzyme inhibitors. The patients were classified according to the Markwalder's Grading Scale. RESULTS: Among these 16 patients, 13 (81.3%) patients showed spontaneously resolved cSDH and 3 (18.7%) patients received surgery due to symptom aggravation and growing hematoma. They were categorized into two groups based on whether they were cured with conservative treatment or not. The first group was the spontaneous resolution group. The second group was the progression-surgery group. The mean hematoma volume in the spontaneous resolution group was 43.1 mL. The mean degree of midline shift in the spontaneous resolution group was 5.3 mm. The mean hematoma volume in the progression-surgery group was 62.0 mL. The mean degree of midline shift in the second group was 6 mm. CONCLUSION: We suggest that the treatment modality should be determined according to the patient's symptoms and clinical condition and close observation could be performed in patients who do not have any symptoms or in patients who have mild to moderate headache without neurological deterioration.

BACKGROUND: The efficacy of oral angiotensin converting enzyme(ACE) inhibitors in the treatment of hypertension has been well documented. Fosinopril is a member of a new class of phosphorous containing ACE inhibitors and is a cleared almost equally by both renal and hepatic routes. METHODS: To evaluate the effects of fosinopril, a new angiotensin converting enzyme inhibitors, in patients with mild to moderate essential hypertension, we administered fosinopril 10~40mg/day once daily to 32 patients(14 males, 18 females; range of age, 40~71 years old) with dose titration every 2 weeks. RESULTS: The baseline blood pressure after 4 weeks wash-out period was 156.3+/-22.3/104.8+/-5.93mmHg. After fosinopril therapy, the blood pressure declined to 150.0+/-27.8/96.4+/-12.2mmHg with 10mmg/day and 144.4+/-20.0/95.21+/-9.95mmHg with 20mg/day, 139.6+/-18.3/85.1+/-9.71mmHg with 30mg/day.During the period of maintenance after dose titration of fosinopril every 2 weeks for 8 weeks, the blood pressure were declined statistically significant (p<0.05). But the heart rate was not changed throughout the period of treatment. The efficacy of fosinopril therapy disclosed 26 patients(81.3%) with normalized diastolic blood pressure and 4 patients(11.8%) with more than 10mmHg decline of diastolic blood pressure. Therefore, the efficacy of fosinopril in these particular patients was 93.1% and two patients(6.9%) showed a failure of fosinopril therapy. The adverse reaction due to fosinopril were reported in 3 patients(9.4%) with dry cough, 1 patients(3.1%) with palpitation and 1 patients(3.1%) with dizziness, but there were patients who discontinued fosinopril due to adverse reaction. CONCLUSION: These results suggested that antihypertensive therapy with fosinopril was effective and well tolerated in patients with mild to moderate essential hypertension.
