Beyond GDMT: bridging the therapeutic gap in heart failure.

Guideline-directed medical therapy is the backbone of heart failure treatment. However, patients continue to experience heart failure symptoms, impaired quality of life, and reduced functional status despite guideline-directed medical and device treatment. There is a void in treatment alternatives between guideline-directed therapy and the advanced heart failure surgical options of heart transplant (HT) and left ventricular assist device (LVAD).

Sympathetic Overdrive and Role of Beta-blockers in Various Forms of Heart Failure: A Consensus Statement from India.

In heart failure, sympathetic overdrive is evidenced by norepinephrine spillover, receptor level changes, etc. Beta-blockers continue to be the cornerstone of treatment in patients with chronic heart failure due to their ability to counteract sympathetic overdrive. Extensive clinical research has demonstrated that long-term beta-blocker treatment with metoprolol succinate, carvedilol, or bisoprolol enhances left ventricular function and reverses left ventricular remodeling, decreases hospitalization risk, and increases survival.

Baroreflex Function in Cardiovascular Disease.

The baroreflex system is involved in modulating several physiological functions of the cardiovascular system and can modulate cardiac output, blood pressure, and cardiac electrophysiology directly and indirectly. In addition, it is involved in regulating neurohormonal pathways involved in the cardiovascular function, such as the renin-angiotensin-aldosterone system and vasopressin release. Baroreflex dysfunction is characterized by sympathetic overactivation and parasympathetic withdrawal and is associated with several cardiovascular diseases, such as hypertension, heart failure, and coronary artery disease.

Outflow Graft Tamponade: An Underrecognized Cause of Obstruction.

Background: Left ventricular assist device (LVAD) outflow graft obstruction can result in severe clinical deterioration. Underlying mechanisms may vary depending on the location. Outflow graft tamponade due to external compression can be under recognized.

F-FDG PET/CT in left ventricular assist device infections: In-depth characterization and clinical implications.

Background: Previous retrospective studies suggest a good diagnostic performance of F-fluorodeoxyglucose positron emission tomography (F-FDG-PET)/computed tomography (CT) in left ventricular assist device (LVAD) infections. Our aim was to prospectively evaluate the role of PET/CT in the characterization and impact on clinical management of LVAD infections.

Methods: A total of 40 patients (aged 58 [53-62] years) with suspected LVAD infection and 5 controls (aged 69 [64-71] years) underwent F-FDG-PET/CT.

Left Ventricular Unloading With Impella Versus IABP in Patients With VA-ECMO: A Systematic Review and Meta-Analysis.

Venoarterial extracorporeal membrane oxygenation (VA-ECMO) use for circulatory support in cardiogenic shock results in increased left ventricular (LV) afterload. The use of concomitant Impella or intra-aortic balloon pump (IABP) have been proposed as adjunct devices for LV unloading. The authors sought to compare head-to-head efficacy and safety outcomes between the 2 LV unloading strategies.

Clinical outcomes of intravenous iron therapy in patients with heart failure and iron deficiency: Meta-analysis and trial sequential analysis of randomized clinical trials.

Background: Iron deficiency in patients with heart failure (HF) is underdiagnosed and undertreated. The role of intravenous (IV) iron is well-established to improve quality of life measures. Emerging evidence also supports its role in preventing cardiovascular events in patients with HF.

Angiotensin Receptor-Neprilysin Inhibitor Therapy and Cardiac Remodeling in Heart Failure: Consensus Statement from India.

Adverse cardiac remodeling refers to progressive structural and functional modifications in the heart because of increased wall stress in the myocardium, loss of viable myocardium, and neurohormonal stimulation. The guideline-directed medical therapy for Heart failure (HF) includes Angiotensin receptor-neprilysin inhibitor (ARNI) (sacubitril/valsartan), β-blockers, sodium-glucose co-transporter 2 (SGLT2) inhibitors, and mineralocorticoid receptor antagonists (MRA). ARNI is under-prescribed in India despite its attractive safety and efficacy profile.

Role of Iron Therapy in Heart Failure: A Consensus Statement from India.

Iron deficiency (ID) with or without anemia is frequently observed in patients with heart failure (HF). Uncorrected ID is associated with higher hospitalization and mortality in patients with acute HF (AHF) and chronic HF (CHF). Hence, in addition to chronic renal insufficiency, anemia, and diabetes, ID appears as a novel comorbidity and a treatment target of CHF.

Meta-Analysis Comparing Outcomes of Remote Hemodynamic Assessment Versus Standard Care in Patients With Heart Failure.

In patients with congestive heart failure (CHF), remote hemodynamic monitoring can reduce heart failure exacerbation and mortality. In this study, we compared the effectiveness of remote hemodynamic monitoring with that of standard care in the management of patients with CHF. The remote monitoring group included 7,733 patients, and the control group included 7,567 patients.

A Rare Case of Blue-Gray Discoloration Induced by Low-Dose Amiodarone.

Amiodarone is increasingly used in cardiology due to convenient dosing, low frequency of pro-arrhythmic effects, and good short term tolerance without significant hypotension. However, chronic use is associated with multisystem toxic side effects. We describe a rare case of amiodarone induced blue-gray skin discoloration.

Heart transplantation in end-stage heart failure secondary to cardiac sarcoidosis: an updated systematic review.

The prevalence of cardiac sarcoidosis is increasing with improved cardiac imaging and may lead to severe heart failure, cardiomyopathy, and arrhythmias that warrant heart transplant consideration. This study aimed to evaluate the outcomes of heart transplantation in sarcoidosis. We systematically searched PubMed/MEDLINE, EMBASE and Cochrane Library following the Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) guidelines.

Meta-Analysis Comparing Venoarterial Extracorporeal Membrane Oxygenation With or Without Impella in Patients With Cardiogenic Shock.

Cardiogenic shock is associated with high short-term mortality. Venoarterial extracorporeal membrane oxygenation (VA-ECMO) is increasingly used as a mechanical circulatory support strategy for patients with refractory cardiogenic shock. A drawback of this hemodynamic support strategy is increased left ventricular (LV) afterload, which is mitigated by concomitant use of Impella (extracorporeal membrane oxygenation with Impella [ECPELLA]).

Benefits of Adding Glucagon-Like Peptide 1 Receptor Agonists to Sodium-Glucose Co-Transporter 2 Inhibitors in Diabetic Patients With Atherosclerotic Disease and Heart Failure.

Sodium-glucose co-transporter 2 inhibitors (SGLT2i) reduce the risk of cardiovascular events and heart failure hospitalization (HFH) in patients with heart failure with reduced ejection fraction (HFrEF), diabetes mellitus type 2 (DM2), and atherosclerotic cardiovascular disease (ASCVD). The role of glucagon-like peptide 1 agonists (GLP1a) in these patients is unclear. We designed this study to assess if the addition of GLP1a to SGLT2i therapy improves outcomes in patients with HFrEF, DM2, and ASCVD.

Clinically Ambiguous Hemorrhagic Cardiac Tamponade Associated with Apixaban.

Hemorrhagic cardiac tamponade in the setting of direct oral anticoagulants (DOACs) is rare but life-threatening. Presentation in subacute cases can also be nonspecific, which can potentially delay diagnosis. A 60-year-old female with a history of heart failure and chronic obstructive pulmonary disease presented with shortness of breath, chest pain, and cough while on treatment with apixaban after a recent hospitalization for pulmonary embolism.
