RESUMEN
To systematically evaluate the clinical efficacy and safety of Compound Danshen Dripping Pills combined with conventional antihypertensive drugs in the treatment of hypertensive left ventricular hypertrophy. China National Knowledge Infrastructure(CNKI), Wanfang, VIP, PubMed, EMbase, Cochrane Library, Ovid and Web of Science databases were searched by computer to retrieve the randomized controlled trials(RCTs) of Compound Danshen Dripping Pills combined with conventional antihypertensive drugs in the treatment of hypertensive left ventricular hypertrophy from the establishment of databases to July 2020. After two researchers performed data retrieval, data extraction, and risk assessment of bias, they used RevMan 5.3 software for Meta-analysis. A total of 10 RCTs were included, with a total of 979 patients. Meta-analysis results showed that in terms of interventricular septal thickness(MD=-0.70, 95%CI[-1.15,-0.24], P=0.003), left ventricular posterior wall thickness(MD=-0.81, 95%CI[-1.41,-0.21], P=0.008), left ventricular mass index(MD=-8.75, 95%CI[-17.40,-0.10], P=0.05), systolic blood pressure(MD=-8.97, 95%CI[-13.46,-4.48], P<0.000 1), diastolic blood pressure(MD=-5.87, 95%CI[-8.39,-3.34], P<0.000 01) and left ventricular end-diastolic diameter(MD=-1.73, 95%CI[-2.38,-1.08], P<0.000 01), Compound Danshen Dripping Pills combined with conventional antihypertensive drugs was superior to conventional antihypertensive drugs. In terms of left ventricular ejection fraction(MD=0.41, 95%CI[-0.74, 1.55], P=0.49), there was no statistical difference in treatment between the two groups. Because of the small amount of literatures included in the safety aspect, it is impossible to give an accurate conclusion. The GRADE score showed that the level of evidence was low and extremely low. The results show that the Compound Danshen Dripping Pills combined with conventional antihypertensive drugs may effectively improve the clinical efficacy for hypertensive ventricular hypertrophy, and the safety needs to be further explored. Due to the low quality of the included literatures, more high-quality RCTs are needed for verification.

BACKGROUND: The myocardial structure differs between secondary left ventricular hypertrophy (LVH) and hypertrophic cardiomyopathy (HCM). We investigated left ventricular function of these two types of hypertrophy using multilayer strain analysis with two-dimensional echocardiography. METHODS: Transthoracic echocardiography (Vivid-E9) was performed in 240 patients with preserved left ventricular ejection fraction (LVEF ≥50%) and with either HCM (n = 80, 63 men, age 49.8 ± 14.1 years), hypertensive LVH (n = 80, 63 men, age 51.4 ± 13.3 years) or normal blood pressure and left ventricular structure (n = 80, 63 men, 50.8 ± 12.4 years). Quantitative multilayer longitudinal strain (LS), circumferential strain (CS), and radial strain (RS) were analyzed. The ratio of endo-/epi-myocardial strain was calculated. RESULTS: Longitudinal strain was significantly (P < 0.001) lower in HCM patients than normal controls (15.2 ± 4.2% vs 23.1 ± 2.7%), especially in hypertrophic segments (14.5 ± 4.4% vs 17.2 ± 3.2% in nonhypertrophic segments, P < 0.01). LS was lower in patients with hypertensive LVH, similarly in all left ventricular segments (20.7 ± 3.7%, P < 0.001 vs controls). CS was lower in the mid- and epicardium (P < 0.01), but not endocardium in HCM (P = 0.4), and preserved in all myocardial layers in hypertensive LVH. The endo-/epi-myocardial ratios of both LS and CS were higher in HCM than hypertensive LVH (P < 0.01). RS was higher (P < 0.01) in HCM than hypertensive LVH and controls. Endocardial CS and global RS were correlated with LVEF (r ≥ 0.32, P < 0.01). CONCLUSIONS: Hypertrophic cardiomyopathy patients had marked reductions in LS and CS, whereas patients with hypertensive LVH had less reduction in LS and preserved CS. The increased endo-/epi-myocardial ratios of LS and CS may be useful in differentiating HCM from hypertensive LVH.
