Latest pharmaceutical approaches across the spectrum of heart failure.

Despite major advances in prevention and medical therapy, heart failure (HF) remains associated with high morbidity and mortality, especially in older and frailer patients. Therefore, a complete, guideline-based treatment is essential, even in HF patients with conditions traditionally associated with a problematic initiation and escalation of the medical HF therapy, such as chronic kidney disease and arterial hypotension, as the potential adverse effects are overcome by the overall decrease of the absolute risk. Furthermore, since the latest data suggest that the benefit of a combined medical therapy (MRA, ARNI, SGLT2i, beta-blocker) may extend up to a LVEF of 65%, further trials on these subgroups of patients (HFmrEF, HFpEF) are needed to re-evaluate the guideline-directed medical therapy across the HF spectrum. In particular, the use of SGLT2i was recently extended to HFpEF patients, as evidenced by the DELIVER and EMPEROR-preserved trials. Moreover, the indication for other conservative treatments in HF patients, such as the intravenous iron supplementation, was accordingly strengthened in the latest guidelines. Finally, the possible implementation of newer substances, such as finerenone, in guideline-directed medical practice for HF is anticipated with great interest.

A Superficial Anatomical Variation in the Radial Artery Renders It Unsuitable as a Graft in Coronary Revascularization.

In our experience, employing a radial artery in combination with an internal thoracic artery under specific conditions represents a superior option compared to using a vein graft in coronary artery surgery. Additionally, this combination is a remarkable alternative to utilizing bilateral thoracic arteries. We had planned the left radial artery as the second target graft in two patients undergoing coronary artery bypass surgery; the left internal thoracic artery to the left anterior descending branch would be the main graft in both patients. Anatomic variation of the radial artery, which presented as a superficial radial artery in both patients, led us to forego the use of the radial artery graft. This decision aimed to ensure sufficient blood supply to the palmar arch and prevent any potential inadequacy in the length of the coronary graft. The occurrence of this variation is exceptionally rare, accounting for approximately 0.02% based on our experience with radial artery harvesting. Furthermore, globally, the documentation of photographs depicting a superficial radial artery is even more infrequent.

Delayed Acute Coronary Syndrome Caused by Multiple Bee Stings: A Rare Case of Kounis Syndrome.

A 51-year-old female patient was admitted to our hospital for medical evaluation and treatment of a syncopal episode following multiple bee stings. The syncopal episode was attributed to an allergic reaction and the patient was treated with intravenous hydration and anti-histamines. Twenty-four hours later, the patient manifested an acute coronary syndrome with chest discomfort, electrocardiographic disorders, and myocardial enzyme motility (including troponin). Coronary angiography was performed without revealing pathological findings and she was diagnosed with Kounis syndrome type I. The management of the patient included administration of single antiplatelet therapy combined with a calcium channel blocker (CCB). The patient follow-up was uncomplicated. In patients with Kounis syndrome type I undergoing a normal coronary angiography, in the absence of specific guidelines, single antiplatelet therapy and CCB may be a reasonable approach.
