Efficacy of Cognitive Behavioral Therapy in Heart Failure Patients: A Systematic Review and Meta-Analysis.

BACKGROUND: Heart failure (HF) is a global disorder affecting around 6.2 million Americans aged 20 years and above. Neurovegetative disorders are common among such patients, and depression is a major problem that affects 20% to 40% of them. Cognitive behavioral therapy (CBT) is a type of treatment that produces the most favorable results compared to other psychotherapies, especially among patients with depression and anxiety. We aim to summarize and synthesize evidence regarding the efficacy of CBT for patients with HF. METHODS: We conducted this study by searching PubMed, Scopus, and Web of Science for relevant studies about CBT use in patients with HF. The outcomes were pooled as mean difference (MD) or standard MD with a 95% CI. The analysis was performed using the RevMan software. RESULTS: Combined data from 9 randomized controlled trials (1070 patients) revealed that CBT can alleviate both depression symptoms in HF patients when measured using different scales after 3 months of follow-up (standard MD, -0.18 [95% CI, -0.33 to -0.02]; P = 0.03) and the quality of life after 3 and 6 months of follow-up (MD, 4.92 [95% CI, 1.14-8.71]; P = 0.01 and MD, 7.72 [95% CI, 0.77-14.68]; P = 0.03, respectively). CONCLUSION: CBT is an effective type of psychotherapy for dealing with depression, mediocre quality of life, and defective physical functioning; therefore, it should be considered in HF patients' care.

A case series of desmoplakin cardiomyopathy: a mimic of viral myocarditis.

Background: Clinical features and imaging presentation of myocarditis can overlap with other inflammatory or arrhythmogenic cardiomyopathies. Desmoplakin (DSP) is an important structural cardiac protein. Mutations in the DSP gene are associated with a variant of arrhythmogenic right ventricular cardiomyopathy (ARVC). Interestingly, this distinct genetic cardiomyopathy can also present with a myocardial inflammation and fibrosis pattern that may mimic other forms of myocarditis including viral myocarditis, which can raise a clinical challenge. We report two cases of DSP cardiomyopathy, which were initially thought to represent coronavirus disease of 2019 (COVID-19) myocarditis. Case summary: First patient is a 21-your-old woman with no past medical history but family history of presumed 'viral myocarditis' and ventricular tachycardia in her brother. She presented with acute chest pain and elevated cardiac enzymes. She tested positive for COVID-19 and given the suspicion for possible COVID-19 related acute myocarditis, cardiac magnetic resonance imaging obtained and revealed regional wall motion abnormalities, several areas of subepicardial and pericardial late gadolinium enhancement (LGE). Ambulatory cardiac monitoring showed runs of non-sustained ventricular tachycardia and considering her family history of arrhythmogenic myocarditis, genetic testing was performed that was positive for a likely pathogenic heterozygous mutation of DSP gene. She declined the recommended implantable cardioverter defibrillator (ICD).Second patient is a 34-year-old physician with no significant past medical history who works at a COVID-19 unit and presented with syncope and was found to have ventricular tachycardia. Echocardiogram revealed severely dilated left ventricle and globally depressed systolic function with left ventricular ejection fraction of 20%. Coronary computed tomography angiography showed no evidence of coronary atherosclerosis. Cardiac magnetic resonance imaging revealed several areas of mid myocardial and pericardial LGE. Subcutaneous ICD was implanted and an endomyocardial biopsy had evidence of lymphocytic myocarditis and adipose tissue infiltration of the myocardium. Genetic testing revealed pathogenic heterozygous DSP mutation. He underwent epicardial ablation for the episodes of ventricular tachycardia despite medical therapy. He was able to return to work and has not had any further episodes of arrhythmia. Conclusion: Mutations in the DSP gene are associated with left dominant arrhythmogenic cardiomyopathy, which is a variant of ARVC. Beside left ventricular systolic dysfunction and ventricular tachyarrhythmias, carriers of these mutations may present with episodes of chest pain associated with elevated cardiac enzymes and cardiac imaging findings indistinguishable from other forms of acute myocarditis including viral myocarditis. Currently, there are no guidelines for diagnosis and treatment of this entity.

Prognostic Value of Venous Thromboembolism Risk Assessment Models in Patients with Severe COVID-19.

Introduction Severe novel corona virus disease 2019 (COVID-19) causes dysregulation of the coagulation system with arterial and venous thromboembolism (VTE). We hypothesize that validated VTE risk scores would have prognostic ability in this population. Methods Retrospective observational cohort with severe COVID-19 performed in NorthShore University Health System. Patients were >18 years of age and met criteria for inpatient or intensive care unit (ICU) care. The International Medical Prevention Registry on Venous Thromboembolism (IMPROVE) and Caprini scores were calculated and patients were stratified. Results This study includes 184 patients, mostly men (63.6%), Caucasian (54.3%), 63 years old (interquartile range [IQR]: 24-101), and 57.1% of them required ICU care. Twenty-seven (14.7%) thrombotic events occurred: 12 (6.5%) cases of disseminated intravascular coagulation (DIC), 9 (4.9%) of pulmonary embolism, 5 (2.7%) of deep vein thrombosis, and 1 (0.5%) stroke. Among them, 86 patients (46.7%) died, 95 (51.6%) were discharged, and 3 (1.6%) were still hospitalized. "Moderate risk for VTE" and "High risk for VTE" by IMPROVE score had significant mortality association: (hazard ratio [HR]: 5.68; 95% confidence interval [CI]: 2.93-11.03; p < 0.001) and (HR = 6.22; 95% CI: 3.04-12.71; p < 0.001), respectively, with 87% sensitivity and 63% specificity (area under the curve [AUC] = 0.752, p < 0.001). "High Risk for VTE" by Caprini score had significant mortality association (HR = 17.6; 95% CI: 5.56-55.96; p < 0.001) with 96% sensitivity and 55% specificity (AUC = 0.843, p < 0.001). Both scores were associated with thrombotic events when classified as "High risk for VTE" by IMPROVE (HR = 6.50; 95% CI: 2.72-15.53; p < 0.001) and Caprini scores (HR = 11.507; 95% CI: 2.697-49.104; p = 0.001). Conclusion The IMPROVE and Caprini risk scores were independent predictors of mortality and thrombotic events in severe COVID-19. With larger validation, this can be useful prognostic information.

Drive-Through Model for Anticoagulation Clinics During the COVID-19 Pandemic.

The coronavirus disease of 2019 (COVID-19) has posed a major challenge for providers and patients. A large number of patients with atrial fibrillation, venous thromboembolism, or valvular heart disease are chronically anticoagulated with vitamin K antagonists and rely on frequent follow ups at anticoagulation clinics for management of their anticoagulation therapy. The need for isolation during COVID-19 pandemic can potentially limit access to health care including anticoagulation clinics and directly affect the care of patients on chronic anticoagulation. Therefore, we created a drive-through clinic to bridge the gap of continuation of care and preservation of social distancing precautions. In this manuscript, we report the steps in implementing such initiative which can be applied to other clinics during a pandemic.

Corynebacterium jeikeium endocarditis: A case report and comprehensive review of an underestimated infection.

Diphtheroids are gram-positive pleomorphic bacilli in the family of Coryneform bacteria. These organisms are present as part of the human flora. Past practice habits had been to consider them as contaminants when isolated from clinical samples. Corynebacterium jeikeium is one of the most clinically important nondiphtherial Corynebacteria that can cause different forms of infections specifically in patients with underlying risk factors and co-morbidities including immunocompromised subjects. Through this article, we present a 67-year-old gentleman with extensive co-morbidities including heart failure with reduced ejection fraction and ESRD on hemodialysis through a femoral catheter who presented with chest pain and fatigue. Further investigation confirmed diagnosis of C. jeikeium endocarditis. We go on to review previously reported cases of C. jeikeium endocarditis and we will discuss different aspects of C. jeikeium infection with a focus on microbiology, pathophysiology, and treatment.
