    Abstract: Ventricular arrhythmia after myocardial infarction is the most important risk factor for sudden cardiac death, which poses a serious threat to human health. As the correlation between autonomic nervous systemic dysfunction and heart rhythm abnormality has been gradually revealed, remedies targeting autonomic nervous system dysfunction, especially the sympathetic nerve, have emerged. Among them, renal denervation is noted for its powerful effect on the inhibition of sympathetic nerve activity. We aim to investigate whether renal denervation can reduce ventricular arrhythmia after myocardial infarction and thus decrease the risk of sudden cardiac death. In addition, we explore the potential mechanism with respect to nerve activity and remodeling. Methods and Results Twenty‐four beagles were randomized into the control (n=4), renal denervation (n=10), and sham (n=10) groups. Permanent left anterior descending artery ligation was performed to establish myocardial infarction in the latter 2 groups. Animals in the renal denervation group underwent both surgical and chemical renal denervation. Compared with dogs in the sham group, dogs in the renal denervation group demonstrated attenuated effective refractory period shortening and inhomogeneity, flattened restitution curve, increased ventricular threshold, and decreased ventricular arrhythmia. Heart rate variability assessment, catecholamine measurement, and nerve discharge recordings all indicated that renal denervation could reduce whole‐body and local tissue sympathetic tone. Tissue analysis revealed a significant decrease in neural remodeling in both the heart and stellate ganglion. Conclusions Surgical and chemical renal denervation decreased whole‐body and local tissue sympathetic activity and reversed neural remodeling in the heart and stellate ganglion. Consequently, renal denervation led to beneficial remodeling of the electrophysiological characteristics in the infarction border zone, translating to a decrease in ventricular arrhythmia after myocardial infarction.

    Abstract: Breastfeeding confers substantial benefits to child health and has also been associated with lower risk of maternal cardiovascular diseases ( CVDs ) in later life. However, the evidence on the effects of CVD is still inconsistent, especially in East Asians, in whom the frequency and duration of breastfeeding significantly differ from those in the West. Methods and Results In 2004–2008, the nationwide China Kadoorie Biobank recruited 0.5 million individuals aged 30 to 79 years from 10 diverse regions across China. During 8 years of follow‐up, 16 671 incident cases of coronary heart disease and 23 983 cases of stroke were recorded among 289 573 women without prior CVD at baseline. Cox regression yielded adjusted hazard ratios ( HR s) and 95% CIs for incident CVD by breastfeeding. Overall, ≈99% of women had given birth, among whom 97% reported a history of breastfeeding, with a median duration of 12 months per child. Compared with parous women who had never breastfed, ever breastfeeding was associated with a significantly lower risk of CVD , with adjusted HR s of 0.91 (95% CI, 0.84–0.99) for coronary heart disease and 0.92 (95% CI, 0.85–0.99) for stroke. Women who had breastfed for ≥24 months had an 18% ( HR, 0.82; 0.77–0.87) lower risk of coronary heart disease and a 17% ( HR, 0.83; 0.79–0.87) lower risk of stroke compared with women who had never breastfed. Among women who ever breastfed, each additional 6 months of breastfeeding per child was associated with an adjusted HR of 0.96 (95% CI, 0.94–0.98) for coronary heart disease and 0.97 (95% CI, 0.96–0.98) for stroke. Conclusions Among Chinese women, a history of breastfeeding was associated with an ≈10% lower risk of CVD in later life and the magnitude of the inverse association was stronger among those with a longer duration of breastfeeding.

    Abstract: Lean body mass has been identified as a key determinant of left ventricular mass and wall thickness. However, the importance of lean body mass or other body‐size measures as normative determinants of carotid intima‐media thickness ( cIMT ), a widely used early indicator of atherosclerosis, has not been well established. Methods and Results Carotid artery ultrasound measurements of cIMT and carotid artery plaque burden (derived from plaque number and maximum size) and measurements of body size, including height, body mass index, weight, body fat proportion, and lean body mass ([1−body fat proportion]×weight), were recorded in 25 020 participants from 10 regions of China. Analyses were restricted to a healthy younger subset (n=6617) defined as never or long‐term ex‐regular smokers aged 〈 60 years (mean age, 50) without previous ischemic heart disease, stroke, diabetes mellitus, or hypertension and with plasma non‐high‐density lipoprotein cholesterol 〈 4 mmol/L. Among these 6617 participants, 86% were women (because most men smoked) and 9% had carotid artery plaque. In both women and men separately, lean body mass was strongly positively associated with cIMT , but was not associated with plaque burden: overall, each 10 kg higher lean body mass was associated with a 0.03 (95% CI , 0.03–0.04) mm higher cIMT ( P =5×10 −33 ). Fat mass, height, and other body‐size measures were more weakly associated with cIMT . Conclusions The strong association of lean body mass with cIMT, but not with plaque burden, in healthy adults suggests a normative relationship rather than reflecting atherosclerotic pathology. Common mechanisms may underlie the associations of lean body mass with cIMT and with nonatherosclerotic vascular traits.

    Abstract: Little is known about the long-term risks of stroke and ischemic heart disease (IHD) in women who had a hysterectomy alone (HA) or with bilateral oophorectomy (HBO) for benign diseases, particularly in China where the burden of cardiovascular diseases (CVD) is high. We assessed mean levels of cardiovascular risk factors and relative risks of stroke and IHD in Chinese women who had a HA or HBO. Methods: A total of 302 510 women, aged 30 to 79 years were enrolled in the China Kadoorie Biobank from 2004 to 2008 and followed up for a mean of 9.8 years. The analysis involved premenopausal women without prior cardiovascular disease or cancer at enrollment. We calculated adjusted hazard ratios for incident cases of CVD and their pathological types (ischemic stroke, hemorrhagic stroke, and IHD) after HA and HBO. Analyses were stratified by age and region and adjusted for levels of education, household income, smoking status, alcohol consumption, physical activity, body mass index, systolic blood pressure, diabetes, self-reported health, and number of pregnancies. Results: Among 282 722 eligible women, 8478 had HA, and 1360 had HBO. Women who had HA had 9% higher risk of CVD after HA (hazard ratio, 1.09 [95% CI, 1.06–1.12]) and 19% higher risk of CVD after HBO (1.19 [95% CI, 1.12–1.26] ) compared with women who did not. Both HA and HBO were associated with higher risks of ischemic stroke and IHD but not with hemorrhagic stroke. The relative risks of CVD associated with HA and HBO were more extreme at younger age of surgery. Conclusions: Women who had either HA or HBO have higher risks of ischemic stroke and IHD, and these risks should be evaluated when discussing these interventions. Additional screening for risk factors for CVD should be considered in women following HA and HBO operations, especially if such operations are performed at younger age.

    Abstract: Self‐rated health ( SRH ) is a strong predictor of mortality in different populations. However, the associations between SRH measures and risk of ischemic heart disease ( IHD ) have not been extensively explored, especially in a Chinese population. Methods and Results More than 500 000 adults from 10 cities in China were followed from baseline (2004–2008) through December 31, 2013. Global and age‐comparative SRH were reported from baseline questionnaires. Incident IHD cases were identified through links to well‐established disease registry systems and the national health insurance system. During 3 423 542 person‐years of follow‐up, we identified 24 705 incident cases of IHD . In multivariable‐adjusted models, both global and age‐comparative SRH was significantly associated with incident IHD . Compared with excellent SRH , the hazard ratios for good, fair, and poor SRH were 1.02 (95% confidence interval [CI], 0.98–1.07), 1.32 (95% CI, 1.27–1.37), and 1.76 (95% CI, 1.68–1.85), respectively. Compared with better age‐comparative SRH , the hazard ratios for same and worse age‐comparative SRH were 1.23 (95% CI, 1.19–1.27) and 1.78 (95% CI, 1.70–1.86), respectively. The associations persisted in all subgroup analyses, although they were slightly modified by study location, education, and income levels. Conclusions A simple questionnaire for self‐assessment of health status was significantly associated with incident IHD in Chinese adults. Individuals and healthcare providers can use SRH measures as a convenient tool for assessing future IHD risk.

    Abstract: In this prospective, randomized, controlled study, we evaluate the safety and change of left ventricular systolic function and infarct area with varied imaging techniques after BMCs transplantation in AMI patients within 3 h after emergency percutaneous coronary intervention (PCI). A total of 271 patients with a first ST-segment-elevation myocardial infarction who had undergone stenting of the infarct-related artery were randomly assigned to receive either unselected BMCs (n=137) transplant or saline (n=134) within 3 hours after successful PCI to the distal vessel of the infarct-related artery through micro-catheter. All patients were followed up within 12 months. Intracoronary BMCs application did not incur cardiovascular events, including ventricular arrhythmias or syncope, occurred during 12-month follow-up. By quantitative LV angiography at six months, LV ejection fraction (LVEF) significantly increased ( p 〈 0.001) and the change of LVEF significantly higher than that in the control group ( p 〈 0.001). Contrast-enhanced magnetic resonance imaging after one year revealed an increased EF (7.7%±6.9%), reduced infarct size (−7.0%±7.5%). In patients with AMI, intracoronary infusion of BMCs within 3 hours after primary PCI is effective and safe in long-term follow-up.

    Abstract: Atorvastatin is a lipid-regulating drug that is commonly used in clinical practice and can stabilize plaques. Increasing evidence shows that statins have anti–heart failure (HF) effects, but their specific mechanism is not clear. The purpose of this study was to investigate the cardioprotective effects of atorvastatin on HF in rats and its mechanism. Continuous intraperitoneal injection of 2.5 mg/kg/w doxorubicin for 6 weeks, with a cumulative dose of 15 mg/kg, was used to induce a rat model of HF. Then, the rats were treated with low-dose atorvastatin, high-dose atorvastatin, or saline for 4 weeks. In the DOX-treated groups, echocardiography showed decreases in left ventricular ejection fraction and fractional shortening and increases in left ventricular end-diastolic diameter and left ventricular posterior wall thickness compared with those in the control group, and increased levels of brain natriuretic peptide and Hsp70 were also found in the doxorubicin-treated groups. Compared with saline intervention, atorvastatin ameliorated left ventricular ejection fraction, fractional shortening, left ventricular end-diastolic diameter, and left ventricular posterior wall thickness (a significant difference was observed only in the high-dose group) and reduced serum brain natriuretic peptide. Hematoxylin and eosin staining showed that atorvastatin ameliorated myocardial injury. The improvement in cardiac function induced by atorvastatin was accompanied by increased Hsp70 expression, decreased p-ERK and p-JNK expression, and a reduction in myocardial fibrosis shown by Masson staining. In addition, atorvastatin had a protective effect on the myocardial apoptosis signaling pathway, with increased p-Akt expression and downregulated cleaved caspase-3 expression, and the reduction in myocardial apoptosis was confirmed by a TUNEL assay. Therefore, our experiments demonstrated that atorvastatin may protect cardiac function by modulating Hsp70, p-Akt, p-ERK, and p-JNK signaling to reduce myocardial fibrosis and myocardial apoptosis.
