BackgroundPersonality factors and psychiatric history may help explain individual differences in risk of psychological morbidity and poor health outcomes in patients with an implantable cardioverter defibrillator (ICD).PurposeWe examined associations between previous anxiety and depressive disorder, type D personality, anxiety or depressive symptoms, and health status in ICD patients prior to ICD implantation.MethodPatients (N = 278; 83 % men; mean age = 62.2 years ±11) receiving a first ICD from September 2007 through April 2010 at the Medisch Spectrum Twente, The Netherlands completed validated questionnaires before implantation assessing type D personality (14-item Type D Scale), anxiety and depressive symptoms (Hospital Anxiety and Depression Scale), and health status (36-item Short Form Health Survey). History of anxiety or depressive disorder was assessed with the Mini International Neuropsychiatric Interview structural interview.ResultsPrevious anxiety or depressive disorder was prevalent in 8 and 19 % of patients, respectively. Type D personality was present in 21 %, depressive symptoms in 15 %, and anxiety in 24 %. In adjusted analyses, type D personality was a dominant correlate of previous depressive disorder (odds ratio (OR) 6.2, p < 0.001) and previous anxiety disorder (OR 3.9, p = 0.004). Type D personality (OR 4.0, p < 0.001), age (OR 1.03, p = 0.043), and gender (OR 2.5, p = 0.013) were associated with anxiety symptoms at baseline. Type D personality (OR 5.9. p < 0.001) was also associated with increased depressive symptoms at baseline. Heart failure and type D personality were related to poorer health status.ConclusionIn ICD patients, prior to ICD implantation, a previous anxiety or depressive disorder, type D personality, and anxiety and depressive symptoms were associated with poorer health status. Type D personality was also independently associated with increased anxiety and depression symptoms.
Women report higher levels of general and shock-related anxiety, and higher levels of body image concerns than men. Women showed more improvement in physical functioning. Screening patients before and after ICD implantation for general and shock anxiety may help determine patients who could benefit from psychological counseling.
Phantom shocks occur in approximately 5 % of all ICD recipients. In primary prevention patients, a relation with a history of atrial fibrillation and NYHA class
BackgroundThe second‐generation cryoballoon significantly improves outcome of pulmonary vein isolation (PVI) but may cause more complications than the first generation. Currently, no consensus regarding optimal cryoballoon application time exists. The 123‐study aimed to assess the minimal cryoballoon application duration necessary to achieve PVI (primary endpoint) and the effect of application duration on prevention of phrenic nerve injury (PNI).MethodsPatients <75 years of age with paroxysmal atrial fibrillation, normal PV anatomy, and left atrial size <40 cc/m² or <50 mm were randomized to two applications of different duration: “short,” “medium,” or “long.” A total of 222 patients were enrolled, 74 per group.ResultsDuration per application was 105 (101‐108), 164 (160‐168), and 224 (219‐226) s and isolation was achieved in 79, 89, and 90% (P < 0.001) of the PVs after two applications in groups short, medium, and long, respectively. Only for the left PVs, the success rate of the short group was significantly less compared to the medium‐ and long‐duration groups (P < 0.001). PNI during the procedure occurred in 19 PVs (6.5%) in the medium and in 20 PVs (6.8%) in the long duration groups compared to only five PVs (1.7%) in the short duration group (P < 0.001).ConclusionsShort cryoballoon ablation application times, less than 2 min, did affect the success for the left PVs but not for the right PVs and resulted in less PNI. A PV tailored approach with shorter application times for the right PVs might be advocated.
A simple risk score based on age, LVEF, eGFR, and atrial fibrillation can identify patients at low, intermediate, and high risk for early mortality after ICD implantation. This may be helpful in the risk assessment of ICD candidates.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
