Myocardial infarction with normal coronary arteries is a well known pathology. It may or may not be associated with left ventricle wall motion abnormalities. Data was reviewed retrospectively for patients with ST elevation myocardial infarction who underwent cardiac catheterization. From the total number of patients evaluated 10.3% (17) patients had Myocardial Infarction with normal coronary arteries. Females were more likely to present with MINCA then males. Coronary flow was normal in 11 from 17 patients with MINCA...

BACKGROUND: Despite the advances in cardiovascular medicine, acute coronary syndrome (ACS) is still a major cause of morbidity and mortality worldwide. Synergy between PCI ™ with TAXUS and Cardiac Surgery (SYNTAX) score is used to determine the extensivity and complexity of coronary artery disease (CAD). Renal resistive index (RRI), a renal Doppler ultrasound parameter, is used to detect renal hemodynamics. Although some risk factors for CAD, including hypertension and diabetes mellitus were demonstrated to have an association with RRI, direct relationship between the presence...

Early detection of vascular inflammation would allow deployment of targeted strategies for the prevention or treatment of multiple disease states. Because vascular inflammation is not detectable with commonly used imaging modalities, we hypothesized that phenotypic changes in perivascular adipose tissue (PVAT) induced by vascular inflammation could be quantified using a new computerized tomography (CT) angiography methodology. We show that inflamed human vessels release cytokines that prevent lipid accumulation in PVAT-derived preadipocytes in vitro, ex vivo, and in vivo...

We present a case of a 47-year-old woman with a mechanical mitral valve prosthesis and recurrent myocardial infarction. The most common etiology of spontaneous myocardial infarction is an acute coronary syndrome caused by rupture or erosion of an atherosclerotic plaque. However, the differential diagnosis in the patient described below also included infarction due to embolization or coronary spasm. It can be challenging to discriminate between the different causes of myocardial infarction based on interpretation of symptoms, physical examination, laboratory tests, and electrocardiography alone...

BACKGROUND: Highly sensitive troponin T (hs-TnT) assay has improved clinical decision-making for patients admitted with chest pain. However, this assay's performance in detecting myocardial ischaemia in a lowrisk population has been poorly documented. PURPOSE: To assess hs-TnT assay's performance to detect myocardial ischaemia at positron emission tomography/CT (PET-CT) in low-risk patients admitted with chest pain. METHODS: Patients admitted for chest pain with a nonconclusive ECG and negative standard cardiac troponin T results at admission and after 6 hours were prospectively enrolled...

Highly active antiretroviral therapy (HAART) has created a new paradigm for human immunodeficiency virus (HIV)-infected patients, but their increased risk for coronary disease is well documented. We present the case of a 57-year-old man, co-infected with HIV-2 and hepatitis B virus, adequately controlled and with insulin-treated type 2 diabetes and dyslipidemia, who was admitted with non-ST elevation acute myocardial infarction. Coronary angiography performed on day four of hospital stay documented two-vessel disease (mid segment of the right coronary artery [RCA, 90% stenosis] and the first marginal)...

BACKGROUND: The implementation of high-sensitivity cardiac troponin T (hs-cTnT) assays and a cutoff based on the 99th cTnT percentile in the evaluation of patients with suspected acute coronary syndrome has not been uniform due to uncertain effects on health benefits and utilization of limited resources. METHODS: Clinical and laboratory data from patients with chest pain or dyspnea at the emergency department (ED) were evaluated before (n = 20516) and after (n = 18485) the lowering of the hs-cTnT cutoff point from 40 ng/L to the 99th hs-cTnT percentile of 14 ng/L in February 2012...

Janarthanan Sathananthan, Vladimír Džavík
Chronic total occlusions (CTOs) are routinely encountered during coronary angiography, but subsequent revascularization rates are low. This has likely been driven by a historical belief that there is minimal clinical benefit and poor success rates with a percutaneous coronary intervention (PCI). However, in the current era, with the development of new techniques and tools, experienced operators can perform CTO-PCI successfully in the majority of patients. The current indications and benefit of CTO-PCI remain a topic of controversy and debate...

BACKGROUND: The prophylactic efficacy of statin pretreatment for the prevention of contrast-induced nephropathy (CIN) in patients undergoing coronary angiography (CAG) or percutaneous coronary intervention (PCI) remains controversial. The aim of the study was to perform a meta-analysis of randomized controlled trials (RCTs) to assess the effectiveness of short-term moderate or high-dose rosuvastatin pretreatment in preventing CIN. METHODS: We included RCTs comparing short-term moderate or high-dose rosuvastatin treatment versus low-dose rosuvastatin treatment or placebo for preventing CIN...

In-stent restenosis (ISR) is a limitation of percutaneous coronary intervention and has been linked to specific clinical and angiographic variables. The aim of the present study was to investigate the predictive value of preprocedural CHA2DS2-VASc score on ISR in patients undergoing revascularization with bare-metal stent (BMS) implantation for stable coronary artery disease or acute coronary syndrome. In the years 2012 to 2014, a total of 358 consecutive patients (mean age: 62.36 ± 11.28 years and 62.2% men) who had undergone successful BMS implantation were included in the study...

In this study, we compared the patients who underwent coronary angiography (CAG), followed by revascularization by coronary artery stent implantation according to the CAG results without any evidence of ischemia with myocardial perfusion scintigraphy (MPS), and the patients who underwent revascularization by coronary artery stent implantation following the detection of ischemia in MPS before CAG in terms of the mortality and hospitalization due to acute coronary syndrome (ACS). Between January 2009 and January 2016, a total of 407 patients (52% males, 48% females; mean age: 66 ± 9 years; range: 40-85 years) who underwent CAG following diagnosis of stable angina and underwent coronary artery stenting were retrospectively analyzed...

OBJECTIVES: We explored the predictors and outcome of poor, versus good, initial TIMI flow in patients with acute coronary syndrome (ACS). DESIGN: We performed post-hoc analysis of a randomized trial of patients presenting with ACS who received 2 comparative stents. Poor initial TIMI flow was defined as baseline TIMI flow grade 0/1 at the initial coronary angiography. The primary endpoint was major adverse cardiac events (MACE): a composite of cardiac death, non-fatal myocardial infarction or ischemia-driven target lesion revascularization...

A 56-year-old woman presented with acute onset of typical chest pain. She was diagnosed with acute coronary syndrome with ST-segment elevation myocardial infarction. Although significant obstructive coronary artery disease was ruled out by coronary angiography, cardiac MRI showed transmural necrosis of the lateral free wall with extensive microvascular obstruction consistent with ischaemic heart disease. Within 48 hours after initial presentation, the patient suddenly arrested due to pulseless electrical activity with futile resuscitation efforts...
