Mineralocorticoid Receptor Antagonists in the Treatment of Coronary Artery Disease, Myocardial Infarction and Heart Failure

Affecting sodium reabsorption and potassium excretion in the kidney, mineralocorticoid receptor antagonists (MRA) were originally developed as antihypertensive drugs. After several large clinical trials, the concept of MR blockade has nowadays become a main treatment paradigm in heart failure with reduced ejection fraction (HFrEF) and for patients after myocardial infarction (MI) with left ventricular (LV) dysfunction. Recent analyses also point to a beneficial effect of early MRA treatment in patients with acute MI without LV dysfunction, however, there is no clear evidence yet. Although promising data from preclinical settings suggest that MRAs mediate favorable anti-atherogenic effects, clinical studies in patients with stable coronary artery disease (CAD) have not been able to detect differences of hard clinical outcomes. The concept might still be pursued using the most recent MRA, like the non-steroidal MR antagonist finerenone, and larger clinical trials need to be performed. Here, we review the current impact of MRA in patients with CAD and focus on the conflicting evidence of preclinical and clinical data in patients with stable CAD and preserved ejection fraction and summarize the current indications for MRA in these patients according to the guidelines

Triple Cannulation ECMO

Extracorporeal membrane oxygenation (ECMO) has emerged as an invaluable tool for bridging severe isolated or combined failure of lung and heart. Due to massive technical improvements, the application of ECMO is growing fast. While historically ECMO was initiated and maintained by cardiac surgeons, in recent times interventional cardiologists and intensive care specialists increasingly run ECMO systems independently with great success. Percutaneous ECMO circuits are usually set up in a dual cannulation mode, either as veno-venous or as veno-arterial configuration. A novel advanced strategy is the cannulation of three large vessels (triple cannulation), resulting in veno-veno-arterial or veno-arterio-venous cannulation. Both veno-venous and veno-arterio-venous cannulation may further be upgraded to veno-pulmonary-arterial or veno-arterial-pulmonary arterial cannulation, respectively. Triple cannulation expands the field of ECMO application but substantially increases the complexity of ECMO circuits. In this chapter, we review percutaneous dual and triple cannulation strategies, featuring a recently proposed unifying nomenclature. This unequivocal code universally applies to both dual and triple cannulation strategies (VV, VPa, VA, VVA, VAV, VAPa). The technical evolution of ECMO is growing fast, but it has to be noted that current knowledge of ECMO support is mainly based on observation. Thus controlled trials are urgently needed to prospectively evaluate different ECMO modes

The year in cardiovascular medicine 2021:heart failure and cardiomyopathies

In the year 2021, the universal definition and classfication of heart failure (HF) was published that defines HF as a cli-cal syndrome with symptoms and/or signs caused by a cardiac abnormality and corroborated by elevated natriuretic peptide levels or objective evidence of cardiogenic congestion. This definition and the classification of HF with reduced ejection fraction (HFrEF), mildly reduced, and HF with pre-served ejection fraction (HFpEF) is consistent with the 2021 ESC Guidelines on HF. Among several other new recommendations, these guidelines give a Class I indication for the use of the sodium-glucose co-transporter 2 (SGLT2) inhibitors dapagliflozin and empagliflozin in HFrEF patients. As the first evidence-based treatment for HFpEF, in the EMPEROR-Preserved trial, empagliflozin reduced the composite endpoint of cardiovascular death and HF hospitalizations. Several reports in 2021 have provided novel and detailed analyses of device and medical therapy in HF, especially regarding sacubitril/valsartan, SGLT2 inhibitors, mineralocorticoid receptor antagonists, ferric carboxymal-tose, soluble guanylate cyclase activators, and cardiac myosin activators. In patients hospitalized with COVID-19, acute HF and myocardial injury is quite frequent, whereas myocarditis and long-term damage to the heart are rather uncommon.</p

A practical approach to the guideline-directed pharmacological treatment of heart failure with reduced ejection fraction

Over the last 15–20 years, remarkable developments of heart failure (HF) pharmacotherapies have been achieved. However, HF remains a global healthcare challenge with more than 64 million patients worldwide. Optimization of guideline-directed chronic HF medical therapy is highly recommended with every patient visit to improve outcomes in patients with HF with reduced ejection fraction. However, the majority of patients in real-world settings are treated with doses that are lower than those with proven efficacy in clinical trials, which might be due to concerns of adverse effects and inertia of physicians. Likewise, a significant proportion of patients still do not receive all drug classes that could improve their prognosis. The recent European Society of Cardiology guidelines do not provide detailed recommendations on how these drug classes should be implemented in the treatment of inpatients to allow for both safety and a high likelihood of efficacy. We therefore propose a practical approach algorithm to support physicians to treat HF patients in their daily practice
