Comparative Assessment of the Long-Term Efficacy of Home-Based Versus Center-Based Cardiac Rehabilitation.

Cardiac rehabilitation programs support the health, wellness, and recovery of patients with cardiovascular conditions. This systematic review attempts to expand these findings while analyzing the latest randomized controlled trials (RCTs) focusing on the long-term advantages of home/center-based cardiac rehabilitation interventions. This study also comparatively analyzes the benefits of opting for home-based cardiac rehabilitation instead of center-based measures to improve the long-term clinical outcomes of cardiac patients. We extracted and analyzed 10 studies (based on 1,549 cardiac patients) concerning the therapeutic efficacy of center/home-based cardiac rehabilitation interventions. The included studies complied with the year range of 2000-2021. The risk of bias assessment was undertaken using the Cochrane Risk-of-Bias tool to evaluate random sequence generation, allocation concealment, blinding of subjects, outcome data completeness, and selective reporting patterns concerning the included RCTs. The findings of our systematic review confirmed the capacity of a home-based cardiac rehabilitation program to effectively improve left ventricular ejection fraction, health-related quality of life, physical fitness, recovery rate, self-efficacy, sedentary lifestyle, physical activity, satisfaction level, functional capacity, social support, and hemodynamic parameters of patients with cardiovascular diseases. Home-based cardiac rehabilitation had the potential to minimize the levels of triglycerides, anxiety, depression, waist circumference, and body mass index/weight of cardiac patients. The results of our systematic review affirmed the long-term therapeutic efficacy of a home-based cardiac rehabilitation program compared to a center-based cardiac rehabilitation program for adult cardiac patients.

Prognostic Value of Cardiovascular Testing in Asymptomatic Patients With a History of Cardiovascular Disease: A Review of Contemporary Medical Literature.

The cardiac stress testing, carotid duplex, coronary artery calcium (CAC) scoring, myocardial perfusion imaging, coronary angiography, C-reactive protein (CRP), glycated hemoglobin (HbA1C), total serum cholesterol, duplex ultrasonography, digital subtraction angiography, magnetic resonance angiography (MRA), computed tomography angiography (CTA), digital subtraction angiography, and ankle-brachial index (ABI) independently predict the risks and prognostic outcomes in asymptomatic cardiovascular disease (CVD) patients. The peripheral artery disease (PAD) screening guides the diagnosis, management, and prognosis of hemodynamically significant arterial stenosis, calcification, and malignant hypertension in patients with CVD without symptoms. The 79% sensitivity and 96% specificity of ABI screening, 90% sensitivity and 97% specificity of MRA, and 95% sensitivity and 50% specificity of CTA for tracking arterial occlusion indicate the high prognostic value of these tests in the setting of CVD. The 85% specificity and 60-70% sensitivity of cardiac stress testing substantiate its suitability to determine asymptomatic CVD prognosis related to myocardial ischemia, heart failure, multivessel disease, and unstable angina. The carotid duplex ultrasound potentially identifies long-term mortality, stroke, atherosclerosis, plaque instability, and angiographic stenosis among asymptomatic CVD patients with 94% specificity and 90% sensitivity. The CAC scoring has a positive predictive value (PPV) of 45.7% for identifying aortic valve calcium and PPV of 79.3% for tracking thoracic artery calcium. The medical literature provides substantial evidence concerning the validity, reliability, and prognostic value of cardiovascular testing for asymptomatic patients. Future studies are needed to undertake detailed assessments of benefits versus adverse outcomes associated with the prospective scaling (of cardiovascular testing) across asymptomatic CVD patients.

Refractory Atrial Fibrillation With Rapid Ventricular Rate in a Patient With Small Cell Carcinoma of the Lung Encasing the Right Pulmonary Artery: A Case Report and Insight Into Therapeutic Options.

Atrial fibrillation is the most common sustained cardiac arrhythmia. While there have been reports of atrial fibrillation caused by the compression of pulmonary veins, we have not found reports of atrial fibrillation caused by the compression of the pulmonary artery. This report highlights the possible pathophysiology and management of atrial fibrillation in a patient with small cell lung cancer. The patient was admitted for hyponatremia secondary to syndrome of inappropriate antidiuretic hormone (SIADH) but subsequently developed tachycardia which progressed to atrial flutter and atrial fibrillation. Antiarrhythmics were ineffective until the patient received his first palliative chemotherapy for his small cell lung cancer. Subsequently, rate control was achieved with sotalol, with eventual conversion back to sinus rhythm. Management of atrial fibrillation is complex and sometimes depends on the underlying etiology. Early chemotherapy, in addition to antiarrhythmic drugs, may be beneficial in the management of patients with small cell lung cancer and atrial fibrillation. The CHA2DS2-VASc score does not take active malignancy into account and anti-coagulation should be evaluated on a case-by-case basis in this patient population.

Association between electronic cigarette use and fragility fractures among US adults.

Background: The popularity of electronic cigarette (e-cigarette) use continues to rise in the United States. While conventional cigarette smoking is an established risk factor for osteoporosis and osteoporotic fracture, the effects of e-cigarette use on bone health are unknown. We aimed to examine the association between e-cigarette use and fragility fractures. Research Design and Methods: We pooled 2017-2018 data from the National Health and Nutrition Examination Survey (NHANES). We included men and women with complete information on key variables. E-cigarette use was categorized as either never or ever users. Ever users were further classified as former and current users. Fragility fracture was defined as a composite of self-reported fracture of the hip, spine or wrist which resulted from minimal trauma such as a fall from standing height or less. Results: Of 5569 participants, there were 4519 (81.2%) never e-cigarette users, 1050 (18.8%) ever e-cigarette users, and 444 (8.0%) with self-reported fragility fracture. In adjusted models, ever e-cigarette users had a 46% higher prevalence of self-reported fragility fractures compared to never users (aPR: 1.46, 95% CI: 1.12, 1.89). We also observed a higher prevalence of fragility fractures among former and current e-cigarette users compared to never users (aPR: 1.89, 95% CI: 1.44, 2.48 and aPR: 1.77, 95% CI: 1.04, 3.02 respectively). Conclusion: E-cigarette use was associated with a higher prevalence of self-reported fragility fracture. These findings suggest that e-cigarette use may be harmful to bone health. These data highlight the critical need for longitudinal studies exploring the potential effect(s) of e-cigarette use on bone health.
