Angiotensin II induces inflammatory activation of vascular smooth muscle cells and can cause left ventricular hypertrophy (LVH). Telmisartan is an angiotensin II receptor blocker with demonstrated beneficial effects on cardiac and vascular structure and function in animal models. The angiotensin-converting enzyme inhibitor ramipril also reduces ventricular and vascular remodelling. The open-label study observed 75 treatment-naïve, moderately or severely hypertensive (systolic blood pressure 160-190 mmHg, diastolic blood pressure 90-110 mmHg) patients (age range, 42-58 years) treated with once-daily telmisartan 40 mg force-titrated to 80 mg after 1 month (n = 25), once-daily ramipril 2.5 mg force-titrated to 5 mg after 1 month (n = 25), or once-daily telmisartan 40 mg plus ramipril 2.5 mg (n = 25); the total duration of treatment was 6 months. At baseline, blood pressure, left ventricular mass index (LVMI), carotid intima-media thickness (IMT) and carotid cross-sectional intima-media area (CSA) were measured. Measurements were repeated 1, 3 and 6 months after initiation of treatment. After 6 months, comparable blood pressure reductions were achieved with the three treatments. Reductions in LVMI after 6 months' treatment were 11.4%, 9.9% and 15.6% with telmisartan, ramipril, and telmisartan plus ramipril, respectively. Respective reductions in IMT were 14.6%, 12.0% and 18.2%, and for CSA were 7.8%, 4.3% and 11.5%. In conclusion, treatment with telmisartan or ramipril for 6 months resulted in regression of LVH and vascular remodelling. When a combination of telmisartan and ramipril was administered, additional regression and remodelling occurred.

Background The first cases of coronavirus disease (COVID-19) in Brazil were diagnosed in February 2020. Our Emergency Department (ED) was designated as a COVID-19 exclusive service. We report our first 500 confirmed COVID-19 pneumonia patients. Methods From 14 March to 16 May 2020, we enrolled all patients admitted to our ED that had a diagnosis of COVID-19 pneumonia. Infection was confirmed via nasopharyngeal swabs or tracheal aspirate PCR. The outcomes included hospital discharge, invasive mechanical ventilation, and in-hospital death, among others. Results From 2219 patients received in the ED, we included 506 with confirmed COVID-19 pneumonia. We found that 333 patients were discharged home (65.9%), 153 died (30.2%), and 20 (3.9%) remained in the hospital. A total of 300 patients (59.3%) required ICU admission, and 227 (44.9%) needed invasive ventilation. The multivariate analysis found age, number of comorbidities, extension of ground glass opacities on chest CT and troponin with a direct relationship with all-cause mortality, whereas dysgeusia, use of angiotensin converting enzyme inhibitor or angiotensin-ii receptor blocker and number of lymphocytes with an inverse relationship with all-cause mortality Conclusions This was a sample of severe patients with COVID-19, with 59.2% admitted to the ICU and 41.5% requiring mechanical ventilator support. We were able to ascertain the outcome in majority (96%) of patients. While the overall mortality was 30.2%, mortality for intubated patients was 55.9%. Multivariate analysis agreed with data found in other studies although the use of angiotensin converting enzyme inhibitor or angiotensin-ii receptor blocker as a protective factor could be promising but would need further studies. Trial registration The study was registered in the Brazilian registry of clinical trials: RBR-5d4dj5.

Abstract Background This study investigated continued and discontinued use of angiotensin-converting enzyme inhibitors (ACEi) or angiotensin II receptor blockers (ARB) during hospitalization of 614 hypertensive laboratory-confirmed COVID-19 patients. Methods Demographics, comorbidities, vital signs, laboratory data, and ACEi/ARB usage were analyzed. To account for confounders, patients were substratified by whether they developed hypotension and acute kidney injury (AKI) during the index hospitalization. Results Mortality (22% vs 17%, P > .05) and intensive care unit (ICU) admission (26% vs 12%, P > .05) rates were not significantly different between non-ACEi/ARB and ACEi/ARB groups. However, patients who continued ACEi/ARBs in the hospital had a markedly lower ICU admission rate (12% vs 26%; P = .001; odds ratio [OR] = 0.347; 95% confidence interval [CI], .187–.643) and mortality rate (6% vs 28%; P = .001; OR = 0.215; 95% CI, .101–.455) compared to patients who discontinued ACEi/ARB. The odds ratio for mortality remained significantly lower after accounting for development of hypotension or AKI. Conclusions These findings suggest that continued ACEi/ARB use in hypertensive COVID-19 patients yields better clinical outcomes.
