Unresolved trauma in spouses as a risk factor for myocardial infarction in men

This paper tests the hypothesis of a high frequency of traumatic events and high levels of alexithymia in wives of individuals with myocardial infarction (MI), assuming that this constellation may have led to choosing a husband with a Type A Behaviour Pattern (TABP)-characterized by irritability, hyper-competition, time urgency and denial of difficulties-which is known to represent an increased risk for MI and to reinforce this pattern. Twenty wives of patients with MI and 20 wives of patients with mild orthopaedic (Orth) problems were administered a Childhood Traumatic Events Scale (CTES) and the TAS-20. MI wives showed higher scores on the CTES than Orth wives; 10 MI wives as against three Orth ones reported a history of very severe childhood trauma. TAS 20 scores were higher in MI than in Orth wives. © 2005 Taylor & Francis Group Ltd

Role of different determinants of psychological distress in acute coronary syndromes

OBJECTIVES: The aim of this study was to examine the prevalence of psychological distress and of its major determinants in acute coronary patients and in a control group. BACKGROUND: The prevalence and major determinants of psychological distress in acute coronary patients are not clear. METHODS: One hundred and thirty cardiac patients (110 men, age 56+/-9; 85 with acute myocardial infarction and 45 with unstable angina) and 102 controls hospitalized for acute trauma (70 men, age 55+/-9 years) were studied and the level of psychological distress estimated by a Modified Maastricht Questionnaire, self-ratings and ratings by a close relative. Major determinants of psychological distress were assessed by the Life Events Assessment, the Social Support Questionnaire and the Ways of Coping Checklist. RESULTS: The average level of psychological distress was significantly higher (p < 0.001) in coronary patients than in controls in all tests (self-evaluation=7.1+/-2.3 vs 4.3+/-2.4; relative-evaluation = 7.4+/-2.4 vs 4.2+/- 2.5; Modified Maastricht Questionnaire=91+/-32 vs 59+/-30). Cardiac patients reported significantly higher (p < 0.05) levels of social isolation (28.9+/-11.1 vs 23.4+/-8.8), self-blame (7.2+/-1.9 vs 5.8+/- 1.6) and avoidance (21.1+/-3.5 vs 18.9+/-3) and more painful life events (3.9+/-3.8 vs 2.6+/-2.2), than controls. However, not all patients had evidence of distress; indeed, cluster analysis identified a subgroup that comprised 75% of controls and 25% of cardiac patients with no determinants eliciting distress, while the other four subgroups, with one or more determinants of distress, comprised about 75% of patients and only 25% of controls. CONCLUSIONS: These results show that a high level of psychological distress is detectable in about 75% of patients with acute myocardial infarction or unstable angina and is related to one or more major determinants

Ventricular rate monitoring as a tool to predict and prevent atrial fibrillation-related inappropriate shocks in heart failure patients treated with cardiac resynchronisation therapy defibrillators

Objective: Inappropriate implantable cardioverter defibrillators (ICD) therapies have been associated with multiple adverse effects, including worse quality of life and prognosis. We evaluated the possibility of predicting atrial fibrillation (AF)-related inappropriate ICD shocks through continuous monitoring of device diagnostics. Methods: 1404 ICD patients were prospectively followed in an observational research by 74 Italian cardiology centres. Device diagnostics stored daily information on AF duration and ventricular rate (VR) during AF. Uncontrolled VR was defined as mean VR>80 beats per minute (bpm) and maximum VR>110 bpm. Expert electrophysiologists reviewed the ventricular tachycardia/ventricular fibrillation (VT/VF) episodes electrograms, stored in the device memory, and classified appropriate detections, inappropriate detection mechanisms and ICD therapy outcomes. Results: Over a median follow-up of 31 months, 511 (36%) patients suffered spontaneous VT/VF, which were treated by ICD shocks in a subgroup of 189 (13%) patients. Inappropriate detections occurred in 232 (16%) patients, and inappropriate ICD shocks in 101 (7%) patients. AF was the cause of inappropriate shocks in 60 patients. AF caused 144 inappropriate shocks: 53% of all inappropriate shocks. The likelihood of experiencing AF-related inappropriate shocks was 2.4% at 1 year and 6% at 5 years. Uncontrolled VR during AF proved to be an independent predictor of AF-related inappropriate shocks (OR=3.02, p=0.006); an alarm set at a VR>90 bpm or 100 bpm was associated with prediction of AF-related inappropriate shocks with a sensitivity of 73% or 62%, respectively. Conclusions: AF is the most common cause of inappropriate shocks in ICD patients. Continuous remote monitoring of VR during AF would promptly and efficiently predict AF-related inappropriate shocks

Seasonal trend of ventricular arrhythmias in a nationwide remote monitoring database of implantable defibrillators and cardiac resynchronization devices

Background: The occurrence of sustained ventricular arrhythmias (SVA) may be influenced by environmental factors. We aimed to investigate annual periodic trends of SVA from the intracardiac electrograms (IEGMs) stored in the implantable defibrillators (ICDs) or cardiac resynchronization therapy (CRT-D) recipients.Methods: Data from the Home Monitoring Expert Alliance project, a pooled repository of remote monitoring transmissions were analyzed. All IEGMs stored were independently adjudicated by three cardiac electrophysiologists. Periodicity of SVA was evaluated with Generalized Estimating Equations (GEE) models, including periodic terms depending on months in a year.Results: A total of 2936 ICD/CRT-D patients (median age 70 years, 79.6% male) were followed for a median period of 25[13-44] months. Most prevalent structural heart diseases were ischemic (50.8%) and idiopathic dilated (30.6%) cardiomyopathies. Overall, 942 (32.1%) patients experienced a total of 4824 SVA. At GEE analysis, we found a significant periodic component (p=0.048) when considering both shocked and non-shocked episodes. SVA less frequently occurred in Junes and Julies (3.7 x 1000 patient-month). No evidence of significant periodicity was collected in the subgroup of ischemic patients.Conclusions: In thisRM-based cohort of ICD/ CRT-T patients, we observed an annual periodicity of SVA occurrence, with a lower incidence in summer months.

Clinical impact of defibrillation testing in a real-world S-ICD population: Data from the ELISIR registry

Background Current guidelines recommend defibrillation testing (DT) performance in patients with a subcutaneous implantable cardioverter defibrillator (S-ICD), theoretically to reduce the amount of ineffective shocks. DT, however, has been proven unnecessary in transvenous ICD and real-world data show a growing trend in avoidance of DT after S-ICD implantation.Methods All patients undergoing S-ICD implant at nine associated Italian centers joining in the ELISIR registry ( Identifier: NCT04373876) were enrolled and classified upon DT performance. Long-term follow-up events were recorded and compared to report the long-term efficacy and safety of S-ICD implantations without DT in a real-world setting.Results A total of 420 patients (54.0 +/- 15.5 years, 80.0% male) were enrolled in the study. A DT was performed in 254 (60.5%) patients (DT+ group), while in 166 (39.5%) was avoided (DT- group). Over a median follow-up of 19 (11-31) months, a very low rate (0.7%) of ineffective shocks was observed, and no significant differences in the primary combined arrhythmic outcome were observed between the two groups (p = .656). At regression analysis, the only clinical predictor associated with the primary combined outcome was S-ICD placement for primary prevention (odds ratio: 0.42; p = .013); DT performance instead was not associated with a reduction in primary outcome (p = .375).Conclusion Implanting an S-ICD without DT does not appear to impact the safety of defibrillation therapy and overall patients' survival

Age-related differences and associated mid-term outcomes of subcutaneous implantable cardioverter-defibrillators: A propensity-matched analysis from a multicenter European registry

BACKGROUND A few limited case series have shown that the subcutaneous implantable cardioverter-defibrillator (S-ICD) system is safe for teenagers and young adults, but a large-scale analysis currently is lacking. OBJECTIVES The purpose of this study was to compare mid-term device-associated outcomes in a large real-world cohort of S-ICD patients, stratified by age at implantation. METHODS Two propensity-matched cohorts of teenagers + young adults (≤30 years old) and adults (>30 years old) were retrieved from the ELISIR Registry. The primary outcome was the comparison of inappropriate shock rate. Complications, freedom from sustained ventricular arrhythmias, and overall and cardiovascular mortality were deemed secondary outcomes. RESULTS Teenagers + young adults represented 11.0% of the entire cohort. Two propensity-matched groups of 161 patients each were used for the analysis. Median follow-up was 23.1 (13.2-40.5) months. In total, 15.2% patients experienced inappropriate shocks, and 9.3% device-related complications were observed, with no age-related differences in inappropriate shocks (16.1% vs 14.3%; P = .642) and complication rates (9.9% vs 8.7%; P = .701). At univariate analysis, young age was not associated with increased rates of inappropriate shocks (hazard ratio [HR] 1.204 [0.675-2.148]: P = .529). At multivariate analysis, use of the SMART Pass algorithm was associated with a strong reduction in inappropriate shocks (adjusted HR 0.292 [0.161-0.525]; P <.001), whereas arrhythmogenic right ventricular cardiomyopathy (ARVC) was associated with higher rates of inappropriate shocks (adjusted HR 2.380 [1.205-4.697]; P = .012). CONCLUSION In a large multicenter registry of propensity-matched patients, use of the S-ICD in teenagers/young adults was safe and effective. The rates of inappropriate shocks and complications between cohorts were not significantly different. The only predictor of increased inappropriate shocks was a diagnosis of ARVC
