Swan-Ganz Catheter and Lack of Evidence: Does it Reflect Clinical Practice?

Joana Carolina Junqueira de Brum et al. Luiz Claudio Danzmann

The physician is faced with a septuagenarian patient with chronic heart failure (HF) of severe ischemic etiology. She progresses with a major hemorrhagic complication after attempted percutaneous revascularization. In spite of volume compensation, she shows signs of respiratory infection, and, notwithstanding adequate antibiotic therapy, she continues to deteriorate clinically with signs of hypoperfusion, albeit with borderline blood pressure levels.

Would indication of invasive hemodynamic monitoring be scientifically associated with reduced clinical outcomes in this case? Acute clinical syndromes imply a greater degree of difficulty for conducting clinical trials, and some approaches applied in practice have not yet been tested in the ideal Cartesian model. The case described above seems to be a good justification for this discussion.

Essential Therapy for Heart Failure with Preserved Ejection Fraction in 2022

Luiz Cláudio Danzmann et al. Joana Carolina Junqueira de Brum Leticia Kunst Priscila Braun Eduardo Lima Garcia

Abstract

Heart failure with preserved ejection fraction (HFpEF) is a syndrome in which there is clinical evidence of heart failure (HF), left ventricle ejection fraction (LVEF) ≥50%, and evidence of diastolic dysfunction and/or structural cardiac changes. The pathophysiology of HF with preserved LVEF is related to the primary morbidities responsible for cardiac and vascular aggression via a chronic proinflammatory state involving the endothelium. Currently, the foundation of management of HFpEF rests on 5 pillars: control of circulatory congestion, management of primary morbidities or etiologies, use of medications with proven clinical benefit, identification and management of secondary etiologies, and cardiopulmonary rehabilitation. Essential therapy for HFpEF is founded on precise diagnosis, definition of etiology, estimation of severity, and use of medications with cardiovascular action of proven efficacy.

Short-Term Effects of a Resistance Training Program Using Elastic Tubing in Patients with Heart Disease

Abstract

Background

Resistance training is effective in cardiac rehabilitation; however, it is conventionally performed using free weights or machines, which can pose logistic challenges to patients with restricted mobility. For its ease of access and cost-effectiveness, elastic tubing is a particularly appealing alternative, but it remains underutilized for this purpose.

Objective

To evaluate muscle strength, functional capacity, aerobic capacity, and quality of life in patients with heart disease in phase II of cardiovascular rehabilitation after a resistance training intervention based solely on elastic tubing.

Methods

Thirteen patients with heart disease (age 63.33±10.80 years) trained with elastic tubing twice weekly for 6 weeks, with progressive load increase every 15 days. The following muscle groups were evaluated and trained: shoulder abductors and flexors, elbow flexors, and knee flexors and extensors. Muscle strength was evaluated using a dynamometer; functional capacity, with a 6-minute walk test and cardiopulmonary exercise test; and quality of life, using the SF-36 questionnaire. Data normality was assessed using the Shapiro–Wilk test. The paired Student’s t-test was used for comparisons before and after training, at a significance level of <5%.

Results

There were significant differences in muscle strength (except for elbow flexion) and functional capacity (485.5 ± 123.3 vs 578.7 ± 110.5; p=0.0399) after the intervention. No statistical differences were found in cardiorespiratory fitness or quality of life.

Conclusions

Short-term resistance training with elastic tubing improved peripheral muscle strength and functional capacity in patients with heart disease, and should be encouraged for this population. (Int J Cardiovasc Sci. 2020; xx(x):xxx-xxx)
