Burn injuries generate multisystem physiological derangements. The authors present a case series of three patients developing acute coronary syndrome (ACS) stemming from coronary vasospasm (CVS) over a course of 5 months. This etiology of ACS is significant as it has previously not been described in burn patients and requires a different management algorithm than vaso-occlusive disease. All patients were admitted to a single accredited burn unit. Burn mechanisms were flash burn, chemical fire, and house fire...

We describe a case of a middle-aged man who presented to the emergency department with typical anginal chest pains and found to have new, deeply inverted T-waves on ECG consistent with Wellens' syndrome. Similar to the description by Wellens et al , a critical 99% stenosis of the proximal left anterior descending artery was indeed confirmed by coronary angiography and successfully treated with drug-eluting stent. It is very important that physicians recognise this ECG finding as a harbinger of a serious cardiovascular condition and the necessity for an early invasive cardiac catheterisation...

BACKGROUND Factor VII-activating protease (FSAP) has a role in vascular inflammation and may have a role coronary artery disease (CAD). The aim of this study was to investigate the association between two naturally occurring single nucleotide polymorphisms (SNPs) in the FSAP gene and the risk of coronary artery disease (CAD). MATERIAL AND METHODS Of 733 patients, 173 patients had symptoms of angina, and 560 patients had CAD confirmed by coronary angiography. All patients were genotyped for SNPs of the FSAP gene, Marburg I (MI-SNP) and Marburg II (MII-SNP), using 5' exonuclease TaqMan assays...

PURPOSE: Age-related aortic changes are related to adverse cardiac remodeling and reduced cardiac function. Here, we aim to assess the correlations between aortic arch width (AAW) and left ventricular (LV) remodeling and LV function as well as coronary artery calcification (CAC). MATERIALS AND METHODS: This retrospective study included 194 patients (ages, 67±12 y) who underwent both coronary computed tomography angiography and echocardiography. The AAW is defined as the longest width between the ascending and descending aorta on a transaxial noncontrast coronary computed tomography angiography image at the level of the pulmonary artery bifurcation...

The presence and extent of myocardial ischemia are the major determinants of prognosis in patients with coronary artery disease (CAD). Unlike coronary angiography alone, fractional flow reserve (FFR) has enabled interventional cardiologists to accurately determine whether coronary atherosclerotic plaques are responsible for myocardial ischemia, and therefore deserve to be revascularized. Areas covered: An overview on the role of FFR in the diagnosis and treatment of coronary artery disease, as well as the potential related controversies is provided...

BACKGROUND: Percutaneous coronary interventions (PCI) of old calcified saphenous vein grafts (SVGs) is challenging and is associated with a considerably high risk of adverse ischemic events in the short- and long-term as compared to native coronary arteries. We report a case in which a non-dilatable, calcified SVG lesion is successfully treated with rotational atherectomy followed by PCI and stenting with local stent delivery (LSD) technique using the Guidezilla™ guide extension catheter (5-in-6 Fr) in the "child-in-mother" fashion...

OBJECTIVE: To determine the impact of the HEART Pathway on healthcare utilization and safety outomes at 1 year in patients with acute chest pain. METHODS: Adult Emergency Department (ED) patients with chest pain (N=282) were randomized to the HEART Pathway or usual care. In the HEART Pathway arm, ED providers used the HEART score and troponin measures (0 and 3-hours) to risk stratify patients. Usual care was based on ACC/AHA guidelines. Major adverse cardiac events (MACE: cardiac death, myocardial infarction [MI], or coronary revascularization), objective testing (stress testing or coronary angiography), and cardiac hospitalizations and ED visits were assessed at 1 year...

BACKGROUND: Coronary computed tomographic angiography (CTA) is a reliable modality to detect coronary artery disease. However, CTA generally overestimates stenosis severity compared with invasive angiography, and angiographic stenosis does not necessarily imply hemodynamic relevance when fractional flow reserve (FFR) is used as reference. CTA-based FFR (CT-FFR), using computational fluid dynamics (CFD), improves the correlation with invasive FFR results but is computationally demanding...

BACKGROUND: Anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA) is a rare congenital coronary anomaly. The enlarged right coronary artery provides retrograde collaterals to supply the left ventricle then preferentially directs into the lower pressure pulmonary artery system causing coronary steal phenomenon. Few patients who survive through adulthood without surgery must have abundant, well-formed functioning collaterals with adequate perfusion of the left ventricle...

BACKGROUND: Despite an increase in the proportion of nonagenarians in demographic structure, there is still a paucity of data on the utilization and outcome of percutaneous coronary interventions (PCIs) in this population. Also, very old patients are under-represented in randomized clinical trials and their treatment is still an emerging challenge. Thus, we sought to compare patient profiles and periprocedural outcomes of PCI in nonagenarians and patients younger than 90 years. PATIENTS AND METHODS: Data were based on the Polish National Registry of PCI (ORPKI)...
