Coronavirus disease 2019 (COVID-19) vaccination is reportedly safe and effective. The histologic features of post-COVID-19 vaccination myocarditis are unknown. We present a case of a 77-year-old Japanese woman diagnosed with eosinophilic myocarditis using endomyocardial biopsy, 7 days after the second dose of BNT162b2 COVID-19 vaccine.

- A study was conducted to explore self-care behaviors in heart failure patients who were hospitalized, using the European Heart Failure Self-Care Behaviour Scale (EHFScBS).
- The research focused on factors like age, gender, living situation, employment, and physical activity, assessing 39 patients with an average age of 81 years.
- Results indicated that physical activity levels were positively associated with self-management behaviors, whereas age showed a negative association, suggesting that self-care education needs to be tailored to each patient's characteristics, primarily age and activity level.
Article Synopsis
- * Out of 665 patients studied, 35% had coronary artery calcification, with 8.2% exhibiting severe stenosis. Various interventions were carried out, both before and after surgery.
- * Findings indicate that coronary artery calcification increases the risk of postoperative cardiac complications, but early intervention by cardiologists significantly mitigates these risks.
Objectives: The purpose of this study was to evaluate the efficacy of plaque debulking by directional coronary atherectomy (DCA) before drug-eluting stent (DES) implantation for bifurcated coronary lesions.
Background: The introduction of DES significantly reduces restenosis and repeated revascularization. However, percutaneous coronary intervention of bifurcated lesions using DES alone remains challenging regardless of whether simple or complex stenting is used.
