A retrospective survey is made on 166 cases of acute myocardial infarction, treated with intravenous nitro-derivatives for eight days of continuous therapy. This therapeutic modality appears to gain four goals: a reduction in mortality of patients, a faster return of ST tract on isoelectric guideline, fewer ventricular pump failures. In the authors' point of view, a delay in the downward return of ST tract towards the isoelectric guideline is an important but ominous prognostic sign in this group of patients. Therefore, this modality of treatment is suggested for all patients with AMI, wherever the myocardial coronary lesion is localized.

Naxos disease is a rare autosomal recessive condition combining arrhythmogenic right ventricular cardiomyopathy, woolly hair, and palmoplantar keratoderma. The first identified causative variant was in the gene encoding the desmosomal protein plakoglobin. Naxos disease exhibits fibro-fatty myocardial replacement with immunohistological abnormalities in cardiac protein and signaling pathways, highlighting the role of inflammation and potential anti-inflammatory treatments.

Marked by iron buildup and lipid peroxidation, ferroptosis is a relatively new regulatory cell death (RCD) pathway. Many diseases like cancer, myocardial ischemia-reperfusion injury (MIRI), neurological disorders and acute renal failure (AKI) are corelated with ferroptosis. The main molecular processes of ferroptosis discovered yet will be presented here, along with the approaches in which it interacts with tumour-associated signaling pathways and its uses in systemic therapy, radiation therapy, and immunotherapy managing tumors.

Fibromuscular dysplasia (FMD) is a non-atherosclerotic, non-inflammatory vascular disease of medium-sized arteries that causes abnormal cellular growth in arterial walls and most commonly affects young to middle-aged women (20-50 years of age). While FMD often involves the renal arteries, it can affect any arterial bed. FMD has a characteristic angiographic appearance of a "string of beads.

Background: Cardiovascular diseases and cancer are leading causes of morbidity and mortality. Patients with malignancies are at increased risk for cardiovascular complications including acute coronary syndromes, chemotherapy or radiation therapy related complications and cardiac metastasis.
Case Summary: We present a case of a 47-year-old female with metastatic cancer on immunotherapy presented with anterior ST elevation myocardial infarction followed by emergent percutaneous coronary intervention in the left anterior descending artery.

Purpose: Young women are at risk of acute coronary syndrome (ACS). They represent a unique population exposed to traditional cardiovascular risk factors and female sex-specific, non-traditional risk factors. The current study aimed to describe traditional and non-traditional risk factors of ACS in young women from the Middle East.
