Heart failure and chronic obstructive pulmonary disease (COPD) are acquiring significant morbidity and mortality and the amalgamation presents many diagnostic challenges. Assessment of cardiac and pulmonary function by echocardiography and pulmonary function tests should be executed in all patients with cautious explanation to avoid misdiagnosis and wrong treatment. Both conditions share overlapping pathophysiological processes. Both functional status and quality of life are greatly influenced by these and associated with high morbidity and mortality rates leading to increase the health-care costs. Although both diseases have been studied extensively, information about the correlation between heart failure and COPD is lacking. Classifying the reason of breathing symptoms among people with both the diseases can be demanding. Therefore it is plausible that a considerable proportion of patients with a diagnosis of COPD have associated heart failure, which ruins unrecognized by primary care physicians or pulmonologists. This study's aim was to assess the relationship between chronic obstructive pulmonary disease and heart failure among elderly patients with chronic cough and dyspnea. This study was done in 100 patient's ≥40 years with a GP (general physician) diagnosis of COPD. Descriptive cross sectional study was carried out in the Department of Medicine, Shaheed Ziaur Rahman Medical College Hospital, Bogra, Bangladesh from November 2011 to April 2012. A total of 100 cases of chronic cough with breathlessness coming into out patient department and admitted into Department of Medicine of Shaheed Ziaur Rahman Medical College Hospital, Bogra, Bangladesh were included according to inclusion and exclusion criteria. Informed written consent was taken from the participants and data was collected by a questionnaire and relevant investigations were done. Data were analyzed with SPSS software and were expressed as mean±SE and significance level of differences among the group was calculated by unpaired student's 't' test. In this study among 100 participating patients with a diagnosis of COPD by their physician, in 24(24%) patients had previously unrecognized heart failure. Pearson Correlation study showed that there is significant positive correlation between FEV₁/FVC and Left Ventricular Diastolic Dysfunction and there is also significant positive correlation between FEV₁/FVC and Total Left Ventricular Dysfunction. By this study we recommend that evaluation and assessment of cardiac status is very important in elderly patients with COPD.

During qualification for mechanical circulatory support, the comprehensive assessment of a patient's mental state is an integral element of the overall medical evaluation. It encompasses a range of psychosocial issues, and as such provides information helpful in the selection of a suitable candidate for the required treatment, and sometimes identifies contraindications to it. It allows ensuring that the patient meets expectations regarding both mental health stability and adherence to medical recommendations.

Background: Atrial fibrillation (AF) is the most prevalent arrhythmia encountered in clinical practice. Triglyceride glucose index (Tyg), a convenient evaluation variable for insulin resistance, has shown associations with adverse cardiovascular outcomes. However, studies on the Tyg index's predictive value for adverse prognosis in patients with AF without diabetes are lacking.

Aims: To study differences in cardiovascular prevention and hypertension management in primary care in men and women, with comparisons between public and privately operated primary health care (PHC).

Methods: We used register data from Region Stockholm on collected prescribed medication and registered diagnoses, to identify patients aged 30 years and above with hypertension. Age-adjusted logistic regression was used to calculate odds ratios (ORs) with 99% confidence intervals (99% CIs) using public PHC centers as referents.

Background: Obesity is a risk factor for heart failure (HF) development but is associated with a lower incidence of mortality in HF patients. This obesity paradox may be confounded by unrecognized comorbidities, including cachexia.

Methods: A retrospective assessment was conducted using data from a prospectively recruiting multicenter registry, which included consecutive acute heart failure patients.

HFpEF is a prevalent and complex type of heart failure. The concurrent presence of conditions such as obesity, hypertension, hyperglycemia, and hyperlipidemia significantly increase the risk of developing HFpEF. Mitochondria, often referred to as the powerhouses of the cell, are crucial in maintaining cellular functions, including ATP production, intracellular Ca regulation, reactive oxygen species generation and clearance, and the regulation of apoptosis.
