    International audienceBackground - The lifesaving benefit of implantable cardioverter-defibrillators (ICDs) has been demonstrated. Their use has increased considerably in the past decade, but related complications have become a major concern. Objective - The purpose of this study was to assess the incidence and effect on outcomes of early (≤30 days) complications after ICD implantation for primary prevention in a large French population. Methods - We analyzed data from 5539 patients from the multicenter French DAI-PP (Défibrillateur Automatique Implantable-Prévention Primaire) registry (2002-2012) who had coronary artery disease or dilated cardiomyopathy and were implanted with an ICD for primary prevention. Results - Overall, early complications occurred in 707 patients (13.5%), mainly related to lead dislodgment or hematoma (57%). Independent factors associated with occurrence of early complications were severe renal impairment (odds ratio [OR] 1.66, 95% confidence interval [CI] 1.17-2.37, P = .02), age ≥75 years (OR 1.01, 95% CI 1.00-1.02, P = .03), cardiac resynchronization therapy (OR 1.58, 95% CI 1.16-2.17, P = .01), and anticoagulant therapy (OR 1.28, 95% CI 1.02-1.61, P = .03). During a mean ± SD follow-up of 3.1 ± 2.3 years, 824 (15.8%) patients experienced ≥1 late complication (>30 days), and 782 (14.9%) patients died. After adjustment, early complications remained associated with occurrence of late complications (OR 2.15, 95% CI 1.73-2.66, P < .0001) and mortality (OR 1.70, 95% CI 1.34-2.17, P = .003). Conclusion - Early complications are common after ICD implantation for primary prevention, occurring in 1 in 7 patients, and are associated with an increased risk of late complications and overall mortality. Further studies are needed to investigate the underlying mechanisms of such associations

    BACKGROUND: Data from several previous studies examining heart-rate and cardiovascular risk have hinted at a possible relationship between heart-rate and non-cardiac mortality. We thus systematically examined the predictive value of heart-rate variables on the subsequent risk of death from cancer. METHODS: In the Paris Prospective Study I, 6101 asymptomatic French working men aged 42 to 53 years, free of clinically detectable cardiovascular disease and cancer, underwent a standardized graded exercise test between 1967 and 1972. Resting heart-rate, heart-rate increase during exercise, and decrease during recovery were measured. Change in resting heart-rate over 5 years was also available in 5139 men. Mortality including 758 cancer deaths was assessed over the 25 years of follow-up. FINDINGS: There were strong, graded and significant relationships between all heart-rate parameters and subsequent cancer deaths. After adjustment for age and tobacco consumption and, compared with the lowest quartile, those with the highest quartile for resting heart-rate had a relative risk of 2.4 for cancer deaths (95% confidence interval: 1.9-2.9, p<0.0001) This was similar after adjustment for traditional cardiovascular risk factors and was observed for the commonest malignancies (respiratory and gastrointestinal). Similarly, significant relationships with cancer death were observed between poor heart rate increase during exercise, poor decrease during recovery and greater heart-rate increase over time (p<0.0001 for all). INTERPRETATION: Resting and exercise heart rate had consistent, graded and highly significant associations with subsequent cancer mortality in men

    BACKGROUND: Incident events of cardiovascular diseases (CVD) are heterogenous and may results in different mortality risks. Such evidence may help inform patient and physician decisions in CVD prevention and risk factor management. AIM: To determine the extent to which incident events of common CVD show heterogeneous associations with subsequent mortality risk in the general population. METHODS: Based on England-wide linked electronic health records, we established a cohort of 1,310,518 people ≥30 years of age initially free of CVD and followed up for non-fatal events of 12 common CVD and cause-specific mortality. The 12 CVD were considered as time-varying exposures in Cox's proportional hazards models to estimate hazard rate ratios (HRR) with 95% confidence intervals (CI). RESULTS: Over the median follow-up of 4.2 years (2010-2016), 81,516 non-fatal CVD, 10,906 cardiovascular deaths, and 40,843 non-cardiovascular deaths occurred. All 12 CVD were associated with increased risk of cardiovascular mortality, with HRR (95% CI) ranging from 1.67 (1.47-1.89) for stable angina to 7.85 (6.62-9.31) for haemorrhagic stroke. All 12 CVD were also associated with increased non-cardiovascular and all-cause mortality risk but to a lesser extent: HRR (95% CI) ranged from 1.10 (1.00-1.22) to 4.55 (4.03-5.13) and from 1.24 (1.13-1.35) to 4.92 (4.44-5.46) for transient ischaemic attack and sudden cardiac arrest, respectively. CONCLUSIONS: Incident events of 12 common CVD show significant adverse and markedly differential associations with subsequent cardiovascular, non-cardiovascular, and all-cause mortality risk in the general population

    International audienceIn the setting of primary prevention of sudden cardiac death, international guidelines (1) recommend an implantable cardioverter-defibrillator (ICD) for symptomatic patients (New York Heart Association [NYHA] functional class II or III) with altered left ventricular ejection fraction (LVEF) (#35%). Our objective was to compare outcomes among patients implanted with a primary prevention ICD according to whether the implantations were guideline-based or not. The DAI-PP (Primary Prevention ICD French Registry) (NCT01992458) enrolled all consecutive patients with ischemic or dilated cardiomyopathy implanted with a primary prevention ICD in 12 French centers between 2002 and 2012 (2). On-guideline patients met both basic criteria, namely, LVEF #35% and NYHA functional class II to III. Off-guideline patients did not meet at least 1 of the 2 criteria. We focused on candidates without an indication for cardiac resynchronization therapy. Vital status and causes of death were ascertained by review of hospital medical files or by communication with primary care physicians, and were corroborated with the French vital status database of the National Institute of Economic Statistics and the French Center on Medical Causes of Death. ICD programming was nonstandardized, although there was a broad consensus between centers (all except 1) concerning the use of high ventricular rates and usually 2 zones (typically ventricular tachycardia >180 beats/min, ventricular fibrillation >220 beats/ min). All data were analyzed using the SAS program version 9.4 (SAS Institute, Cary, North Carolina). Of a total of 5,539 patients enrolled in DAI-PP study, 2,538 were implanted with a single-or double-chamber ICD. Mean age was 60.2 AE 11.7 years, 1,694 (87.4%) were men, 1,379 (71.9%) had ischemic car-diomyopathy, mean LVEF was 28.2 AE 8.6%, and 853 (59.3%) had a QRS width <120 ms. Guideline eligibility for implantation could be eventually ascertained in 1,939 patients (76.4%). Overall, 500 patients (25.8%) were identified to be implanted off-guideline, with a mean LVEF about 33.8 AE 12.7% and with 418 (83.6%) having an NYHA functional class I or IV. We observed no significant intergroup differences in age, sex, type of cardiomyopathy, type of ICD, and sinus rhythm. Over time, the proportion of off-guideline patients remained unchanged (p ÂĽ 0.48). On-guideline patients had a sicker clinical profile with a lower mean LVEF (26.3 AE 5.4% vs. 33.8 AE 12.7% for on-guideline vs. off-guideline patients, respectively

    International audienceBACKGROUND:The benefit of ideal cardiovascular health (CVH) on health-related outcomes in middle-aged patients is firmly established. In the growing elderly population, the high prevalence of comorbidities and medications for chronic diseases may offset such benefit.OBJECTIVES:This study analyzed the association of ideal CVH with mortality, incident coronary heart disease, and stroke events in elderly individuals from the community.METHODS:Between 1999 and 2001, 9,294 men and women, noninstitutionalized and aged 65 years and over were examined, and thereafter followed up for the occurrence of vascular events and mortality within the Three-City Study. Hazard ratios (HRs) were estimated by Cox proportional hazard model and compared subjects with 3 to 4 and subjects with 5 to 7 ideal metrics with those with 0 to 2 ideal metrics, respectively.RESULTS:The mean age was 73.8 ± 5.3 years, and 36.7% were men. Only 5% of the participants had ≥5 metrics at the ideal level. After a median follow-up of 10.9 years and 8.6 years, respectively 1,987 deaths and 680 adjudicated coronary heart disease or stroke events had occurred. In multivariate analysis, the risk of mortality and of vascular events decreased across the categories of ideal metrics. In particular, in subjects with ≥5 metrics at the ideal level (compared with those with ≤2), there was a 29% (hazard ratio [HR]: 0.71; 95% confidence interval [CI]: 0.55 to 0.90) decreased risk of all-cause mortality and 67% (HR: 0.33; 95% CI: 0.19 to 0.57) for coronary heart disease and stroke combined (p for trend <0.001).CONCLUSIONS:Even in the elderly, higher CVH status is highly beneficial regarding mortality and vascular event risks
