Patient Perception, Knowledge and Adaptation in The Management of Heart Failure: A Multicenter, Cross-Sectional, Observational, Questionnaire-Based Study: ADAPTATION HF.

OBJECTIVE: The aim of this study is to reveal the perception levels of heart failure (HF) patients about the disease, their adaptation to the disease process, their compliance with the treatment, and their knowledge and thoughts about the disease from the patient's perspective. METHOD: Patients with a diagnosis of HF for at least 6 months who applied to the cardiology clinics of 10 different centers were included in this cross-sectional, multicenter and questionnaire-based study. A questionnaire consisting of sections that included demographic information, evaluation of the patient's symptoms, knowledge and experience of clinical follow-up, knowledge of HF, compliance and awareness of treatment was applied to the patients. RESULTS: 504 patients with a mean age of 59.8 ± 14.9 years (M/F: 360/144, 71.4%/28.6%) were included in the study. 61.2% of the patients stated that they knew about HF disease before. Most of the patients knew that the complaints of shortness of breath, fatigue and palpitation could develop due to HF (95.4%; 92.7%; 89.7%, respectively). The patients reported that they were mostly worried about not being able to provide their own self-care without the support of another person (67.5%). While the majority of patients (37.6%) thought that the worst disease was to have a cerebrovascular disease; only 10.9% stated that HF was the worst disease. While 98.8% of the patients stated that they used HF drugs regularly, a relatively large part of the patients did not know that the drugs were effective on kidney functions (68.5%) and blood pressure (76.9%). In the daily practice of the patients, the rate of weight follow-up was 35.5%, the rate of blood pressure monitoring was 26.9%, and the rate of patients who exercised was 27%. Among the patients, 73.3% said that they pay attention to the amount of salt they take with diet, and 33.5% have a completely salt.free diet. There was no difference between the groups with low and high knowledge scores in terms of Pittsburgh Sleep Quality Index (P > 0.005). The knowledge level score was significantly higher in patients with previous myocardial infarction (P = 0.002). CONCLUSION: Most of the HF patients participating in the study are aware of the signs and symptoms of HF, follow the recommendations of their physicians, and use drugs regularly. These patients should have more information about blood pressure monitoring, weight monitoring, diet and sodium restriction, exercise, which are included in the non-pharmacological part of treatment management.

Prognostic nutritional index as a novel marker for prediction of prognosis in patients with peripartum cardiomyopathy.

The clinical significance of poor nutritional status in patients with peripartum cardiomyopathy (PPCM) is not clearly understood. Prognostic nutritional index (PNI) is a simple nutritional assessment tool, which was first demonstrated to be valuable in patients with colorectal surgeries. We aimed to investigate the predictive value of PNI in patients with PPCM.A total of 92 patients diagnosed with PPCM were enrolled in this study. PNI was calculated using the following formula: 10 × serum albumin value (g/dL) + 0.005 × total lymphocyte count. The primary endpoint was defined as composite adverse cardiac events that included cardiac death or hospitalization due to worsening heart failure (HF). Cardiac death, hospitalization due to worsening HF, and persistent left ventricular (LV) systolic dysfunction were evaluated, respectively, as secondary endpoints.Primary composite endpoint was higher in the lower PNI group. After adjusting for other risk factors, PNI was found to be as an independent predictor of primary composite endpoint (odds ratio 0.805; 95% confidence interval 0.729-0.888; P < .001). In addition, PNI was significantly associated with secondary endpoints; persistent LV systolic dysfunction as well as cardiac death.This study identified nutritional status assessed by the PNI seems to be a novel predictor of adverse cardiovascular outcomes in patients with PPCM.

Importance of lead aVR on predicting adverse cardiac events in patients with noncompaction cardiomyopathy.

BACKGROUND: Noncompaction cardiomyopathy (NCCM) is a relatively rare cardiac abnormality with high rates of mortality and morbidity. T-wave amplitudes during ventricular repolarization in lead aVR (TaVR) have been reported to be associated with the prognosis of various cardiovascular diseases. This study sought to investigate the prevalence and prognostic role of positive TaVR in patients with NCCM. METHODS: We evaluated consecutive 161 patients with NCCM (65.8% men, mean age 42.5 ± 15.2 years old). Presentation electrocardiogram was assessed regarding classical parameters as well as T-wave amplitudes in lead aVR. The primary endpoint was defined as composite lethal arrhythmic events, including sudden cardiac death, ventricular fibrillation, or sustained ventricular tachycardia or appropriate implantable cardioverter-defibrillator shock. Heart failure requiring hospitalization, cardiovascular death, and all-cause mortality were also investigated as secondary endpoints. RESULTS: Patients with positive TaVR showed higher rates for arrhythmic events, hospitalization for heart failure, and death compared with patients without it. In multivariate Cox model, after adjusting for other known clinical and electrocardiographic risk factors, the positive TaVR was found to be a strong independent predictor of primary endpoint (HR: 4.8, 95% CI: 1.2-19.3; p = .025) and all-cause death (HR: 3.5, 95% CI: 1.0-12.1; p = .045). CONCLUSION: Our findings revealed that positive TaVR is significantly and independently associated with adverse outcomes in NCCM patients. This unique ECG criterion in the often ignored lead provides incremental information beyond what is available with other traditional risk factors.

Fragmented QRS as a candidate marker for left ventricular nonrecovery in patients with peripartum cardiomyopathy.

BACKGROUND: Fragmented QRS (fQRS) complex, with various morphology, has been recently described as a diagnostic criterion of several cardiac diseases. However, there are little data regarding the prognostic role of fQRS in peripartum cardiomyopathy (PPCM) patients. We aimed to investigate the effect of fQRS on predicting left ventricular (LV) nonrecovery in patients with peripartum cardiomyopathy (PPCM). METHODS: Ninety patients (mean age: 34.7 ± 6.5 years) with the diagnosis of PPCM were analyzed retrospectively. The median follow-up period of was 67.0 (12.0-192.0) months. Fragmented QRS was defined as the presence of various RSR' patterns (QRS duration < 120 ms) with or without Q wave, which include an additional R wave (R' prime) or notching of the R wave or S wave, or the presence of more than one R' (fragmentation) without typical bundle branch block. Recovery of LV function was defined as the presence of LV ejection fraction (EF) >45%. RESULTS: Of the patients, 54 (60%) did not recover LV function at the last follow-up visit (nonrecovery group), while 36 of the patients (40%) exhibited LV recovery (recovery group). LV ejection fraction (EF) and fQRS were identified as independent predictors of LV nonrecovery in patients with PPCM (odds ratio OR: 5.546, 95% confidence interval CI: 0.792-0.979, p = .019 and OR: 5.986, 95% CI: 1.313-11.787, p = .014, respectively). CONCLUSION: Our data firstly indicated that presence of fQRS was a significant predictor of LV nonrecovery in patients with PPCM. The fQRS might assist in identifying high-risk patients.
