Two recent large trials showed the potential of single pill combinations (SPCs) with ≥3 low-dose components among people with hypertension who were untreated or receiving monotherapy. In both trials, these ‘hypertension polypills’ were superior to usual care, achieving >80% BP control without increasing withdrawal due to side effects. However, there are no such products available for prescribers. To address this unmet need, George Medicines developed GMRx2 with telmisartan/amlodipine/indapamide in three strengths (mg): 10/1.25/0.625, 20/2.5/1.25; 40/5/2.5. Two pivotal trials are ongoing to support FDA submission for the treatment of hypertension, including initial treatment. These assess efficacy and safety of GMRx2 compared to: placebo, and each of the three possible dual combinations. Regulatory submissions are planned for 2024, with the aim of providing access to GMRx2 in developed and developing regions. Wider implementation of GMRx2-based treatment strategies will be guided by further research to inform access and appropriate scale up.

Objective: To assess whether inter-professional, bidirectional collaboration between general practitioners (GPs) and pharmacists has an impact on improving cardiovascular risk outcomes among patients in the primary care setting. It also aimed to understand the different types of collaborative care models used. Study design: Systematic review and Hartung-Knapp-Sidik-Jonkman random effects meta-analyses of randomised control trials (RCTs) in inter-professional bidirectional collaboration between GP and pharmacists assessing a change of patient cardiovascular risk in the primary care setting. Data sources: MEDLINE, EMBASE, Cochrane, CINAHL and International Pharmaceutical Abstracts, scanned reference lists of relevant studies, hand searched key journals and key papers until August 2021. Data synthesis: Twenty-eight RCTs were identified. Collaboration was associated with significant reductions in systolic and diastolic blood pressure (23 studies, 5,620 participants) of –6.42 mmHg (95% confidence interval (95%CI) –7.99 to –4.84) and –2.33 mmHg (95%CI –3.76 to –0.91), respectively. Changes in other cardiovascular risk factors included total cholesterol (6 studies, 1,917 participants) –0.26 mmol/L (95%CI –0.49 to –0.03); low-density lipoprotein (8 studies, 1,817 participants) –0.16 mmol/L (95%CI –0.63 to 0.32); high-density lipoprotein (7 studies, 1,525 participants) 0.02 mmol/L (95%CI –0.02 to 0.07). Reduction in haemoglobin A1c (HbA1C) (10 studies, 2,025 participants), body mass index (8 studies, 1,708 participants) and smoking cessation (1 study, 132 participants) was observed with GP-pharmacist collaboration. Meta-analysis was not conducted for these changes. Various models of collaborative care included verbal communication (via phone calls or face to face), and written communication (emails, letters). We found that co-location was associated with positive changes in cardiovascular risk factors. Conclusion: Although it is clear that collaborative care is ideal compared to usual care, greater details in the description of the collaborative model of care in studies is required for a core comprehensive evaluation of the different models of collaboration.

Vital Signs During the COVID-19 Outbreak: A Retrospective Analysis of 19,960 Participants in Wuhan and Four Nearby Capital Cities in China. Global Heart. 2021;16(1):47. DOI: http://doi.org/10.5334/gh.913.

Background: The implications of city lockdown on vital signs during the COVID-19 outbreak are unknown. Objective: We longitudinally tracked vital signs using data from wearable sensors and determined associations with anxiety and depression. Methods: We selected all participants in the HUAWEI Heart Study from Wuhan and four nearby large provincial capital cities (Guangzhou, Chongqing, Hangzhou, Zhengzhou) and extracted all data from 26 December 2019 (one month before city lockdown) to 21 February 2020. Sleep duration and quality, daily steps, oxygen saturation and heart rate were collected on a daily basis. We compared the vital signs before and after the lockdown using segmented regression analysis of the interrupted time series. The depression and anxiety cases were defined as scores ≥8 on the Hospital Anxiety and Depression Scale depression and anxiety subscales [HADS-D and HADS-A] in 727 participants who finished the survey. Results: We included 19,960 participants (mean age 36 yrs, 90% men). Compared with pre-lockdown, resting heart rate dropped immediately by 1.1 bpm after city lockdown (95% confidence interval [CI]: –1.8, –0.4). Sleep duration increased by 0.5 hour (95% CI: 0.3, 0.8) but deep sleep ratio decreased by 0.9% (95% CI: –1.2, –0.6). Daily steps decreased by 3352 steps (95% CI: –4333, –2370). Anxiety and depression existed in 26% and 17% among 727 available participants, respectively, and associated with longer sleep duration (0.2 and 0.1 hour, both p < 0.001). Conclusions: Lockdown of Wuhan in China was associated with an adverse vital signs profile (reduced physical activity, heart rate, and sleep quality, but increased sleep duration). Wearable devices in combination with mobile-based apps may be useful to monitor both physical and mental health. Clinical trial registration: The trial is registered at Chinese Clinical Trial Registry (ChiCTR) website (ChiCTR-OOC-17014138).
