Cardiac troponins are highly sensitive and specific markers of early detection of myocardial injury. The incidence of cardiac troponin increase is of 5-40% after percutaneous coronary interventions and is significantly higher in patients undergoing stenting than in patients with balloon angioplasty only. Four mechanisms are responsible for myocardial necrosis during coronary angioplasty: 1) distal embolization of small fragments of the atherosclerotic plaque; 2) side branch occlusion; 3) intimal dissection, and 4) temporary vessel occlusion. The multiple and/or complex lesions, the diabetic status and plaque instability increase the probability of troponin elevation during coronary angioplasty. Moreover, the long time needed for interventional as well as atherectomy procedures may induce myocardial necrosis. In conclusion, after successful percutaneous coronary interventions, minor elevation of troponin may occur. In this setting cardiac troponin I is a highly specific marker of myocardial injury.

Background: Shortened door-to-balloon time (D2B) has been documented to confer cardiovascular benefits for ST-elevation myocardial infarction (STEMI) patients undergoing primary percutaneous coronary intervention (PPCI). However, prolonged myocardial ischemic duration usually negates the beneficial effects due to delayed symptom-to-door time (S2D). In this study, we sought to investigate the joint effect of S2D-D2B in predicting clinical outcomes.

Background: There exists clinical equipoise regarding whether and when an invasive approach should be preferred over conservative treatment in the management of stable late ST-elevation myocardial infarction (STEMI) presenting within 12 to 72 h of symptom onset.
Objective: To perform a systematic review to identify the most effective treatment strategy between percutaneous coronary intervention (PCI) and medical therapy in stable late STEMI presenters by comparing their respective outcomes as well as determine the optimal timing of PCI by evaluating the outcomes of urgent versus non-urgent PCI approach in this patient population.
Methods: PubMed, Embase, and Cochrane databases were queried from inception until March 2024 for studies comparing the outcomes of PCI versus medical therapy, as well as urgent versus non-urgent PCI, in stable late STEMI patients presenting with symptom onset within 12-72 h.

Background: In patients with ST-segment elevation myocardial infarction (STEMI) and multivessel coronary artery disease, most but not all randomized trials have reported that complete revascularization (CR) offers advantages over culprit vessel-only revascularization. In addition, the optimal timing and assessment methods for CR remain undetermined.
Objectives: The purpose of this study was to identify the optimal revascularization strategy in patients with STEMI and multivessel disease, using a network meta-analysis of randomized controlled trials.

Arteriovenous malformations (AVMs) are rare congenital vascular malformations with associated morbidities. We describe a neonatal case of upper limb high-flow AVM presenting with upper limb soft tissue mass and postnatal high-output heart failure. Doppler study suggested high-flow AVM, and later magnetic resonance angiography of the right upper limb confirmed the diagnosis.
