BACKGROUND: The adoption of prospectively ECG-triggered acquisition coronary computed tomography angiography (CTA) has resulted in the inability to measure left ventricle (LV) end-diastolic volume and LV ejection fraction. However other prognostic measures such as LV mass and LV mid-diastolic volume (LVMDV) can still be assessed. The objective of this study is to establish normal reference values for LVMDV and LV mass. METHODS: Left ventricular mid-diastolic volumes and LV mass were prospectively measured in 2647 consecutive 'normal' patients undergoing prospectively ECG-triggered coronary CTA...

BACKGROUND: Antiphospholipid antibody syndrome (APS) is a disorder associated with both arterial and venous thromboembolic disease, including acute myocardial infarction (AMI). Given that management with anticoagulants is critical and differs from usual AMI care, identification of key discriminators of patients with AMI with APS is important. METHODS: We performed an English-language systematic review of the literature of cases and case series of patients with AMI and APS from inception until 20 March 2016, collecting demographics, investigations, and outcomes...

BACKGROUND: Spontaneous healing of spontaneous coronary artery dissection (SCAD) and left ventricular ejection fraction (LVEF) recovery is frequently observed clinically. However, LVEF on presentation and follow-up imaging has not been described. HYPOTHESIS: We hypothesize that LV dysfunction improves at follow-up after initial SCAD presentation. METHODS: We included patients with nonatherosclerotic SCAD prospectively followed at Vancouver General Hospital, who had baseline assessment of LVEF and wall-motion abnormality (WMA) during their index presentation...

INTRODUCTION: Aortic valve sclerosis has been shown to be associated with increased incidence, chances of developing myocardial infarction and even death. The epidemiological risk factors causing calcification of aortic valves have also been found to cause atherosclerosis. AIM: To analyse the epidemiological risk factors causing aortic valve sclerosis which have been studied in details and analysed to see whether they cause any significant increase in the incidence of cardiovascular events...

BACKGROUND: Comparing the prognostic value of a negative finding by stress single-photon emission computed tomography myocardial perfusion imaging (MPI) and coronary computed tomography angiography (CCTA) may be useful to evaluate how better identify low-risk patients. We performed a meta-analysis to compare the long-term negative predictive value (NPV) of normal stress MPI and normal CCTA in subjects with suspected coronary artery disease (CAD). METHODS AND RESULTS: Studies published between January 2000 and November 2016 were identified by database search...

The use of energy drinks, which often contain stimulants, is common among young persons, yet there have been few reports of adverse cardiac events. We report the case of a 27-year-old man who was admitted to our facility with an acute ST-segment elevation myocardial infarction in the setting of using energy drinks. Angiography revealed no obstructive coronary disease. The patient had elevation of cardiac troponin. Noninvasive testing with echocardiography and cardiac magnetic resonance imaging demonstrated both abnormalities in resting wall motion at the anterior apex along with late gadolinium enhancement of the anterior wall, respectively...

Importance: Guidelines recommend noninvasive testing for patients with stable chest pain, although many subsequently have normal test results and no adverse clinical events. Objective: To describe a risk tool developed to use only pretest clinical data to identify patients with chest pain with normal coronary arteries and no clinical events during follow-up (minimal-risk cohort). Design, Setting, and Participants: This secondary analysis of a randomized, pragmatic comparative effectiveness trial (Prospective Multicenter Imaging Study for Evaluation of Chest Pain [PROMISE]) includes stable, symptomatic outpatients without known coronary artery disease referred for noninvasive testing at 193 sites in North America...

We present a case of a 35-year-old male patient with a 12-hour history of sudden-onset, crushing chest pain and associated complaints of profuse diaphoresis, nausea and vomiting. The patient was transferred to our institution from an outside hospital for evaluation and possible emergent catheterization. Left heart catheterization was conclusive for normal coronary arteries and a ventriculogram revealed a left ventricular ejection fraction of approximately 45%. Due to a suspicion of myocarditis based on clinical history, pertinent serology tests were ordered, which were found to be negative...

: "No reflow" phenomenon is a common complication with significant prognostic repercussions after reperfused acute myocardial infarction. Previous studies have shown the feasibility and prognostic significance of coronary microcirculation assessment by transthoracic Doppler of left anterior descending artery (LAD). The aim of the study was to evaluate the time course of the coronary microcirculation status after acute anterior myocardial infarction reperfused by primary angioplasty with stent on LAD...

Double right coronary artery (RCA) is an extremely rare coronary artery anomaly. We here report an atherosclerotic double RCA which appeared after primary percutaneous intervention performed to treat a 34-year-old male presenting with acute inferior myocardial infarction, cardiogenic shock and complete heart block. This is an unusual case as double RCA had been hidden by total atherosclerotic occlusion of the proximal part of the RCA and complete restoration of patency led complete heart block back to normal sinus rhythm...

The release of myocardial necrosis biomarkers after off-pump coronary artery bypass grafting (OPCAB) frequently occurs. However, the correlation between biomarker release and the diagnosis of procedure-related myocardial infarction (MI) (type 5) has been controversial. This study aimed to evaluate the amount and pattern of cardiac biomarker release after elective OPCAB in patients without evidence of a new MI on cardiac magnetic resonance (CMR) imaging with late gadolinium enhancement (LGE).Patients with normal baseline cardiac biomarkers referred for elective OPCAB were prospectively included...

AIM: To assess the prevalence of depressed heart rate variability (HRV) after an acute myocardial infarction (MI), and to evaluate its prognostic significance in the present era of immediate reperfusion. METHODS: Time-domain HRV (obtained from 24-h Holter recordings) was assessed in 326 patients (63.5 ± 12.1 years old; 80% males), two weeks after a complicated MI treated by early reperfusion: 208 ST-elevation myocardial infarction (STEMI) patients (in which reperfusion was successfully obtained within 6 h of symptoms in 94% of cases) and 118 non-ST-elevation myocardial infarction (NSTEMI) patients (percutaneous coronary intervention was performed within 24 h and successful in 73% of cases)...

Atrial myxoma is a cardiac tumor often histologically benign but very insidious for its mechanical complications. Among these, myocardial infarction can be an expression of coronary embolism. Imaging techniques are essential for the diagnosis and the therapeutic steps. We describe the clinical case of a 52-year-old woman with acute myocardial infarction and normal coronary arteries with left atrial myxoma. We conducted a review of published case reports over the last 45 years on the rare association between atrial myxoma and acute myocardial infarction, to obtain pathogenic and epidemiological information from the real world...

BACKGROUND: This study aims to explore the application value of thromboelastogram (TEG) in antiplatelet therapy in coronary artery intervention. METHODS: A retrospective analysis of 90 cases of coronary interventional treatment was conducted in our hospital from January 2010 to January 2012. Cases were divided into three groups, according to the kind of coronary heart disease: angina pectoris (AP) group (30 cases), unstable angina pectoris (UAP) group (30 cases) and acute myocardial infarction (AMI) group (30 cases)...

Myocardial infarction (MI), a subset of acute coronary syndrome, is damage to the cardiac muscle as evidenced by elevated cardiac troponin levels in the setting of acute ischemia. Coronary artery disease is the leading cause of mortality in the United States. Chest pain is a common presentation in patients with MI; however, there are multiple noncardiac causes of chest pain, and the diagnosis cannot always be made based on initial presentation. The assessment of a possible MI includes evaluation of risk factors and presenting signs and symptoms, rapid electrocardiography, and serum cardiac troponin measurements...

BACKGROUND: Plasma transfusion is a common clinical practice. Remote ischemic preconditioning (RIPC) protects organs against ischemia-reperfusion (IR) injury. Whether preconditioned plasma (PP), collected at late phase after RIPC, could protect organs against IR injury in vivo is unknown. This study explored whether transfusion of PP could reduce myocardial infarct size (IS) after IR in rat in vivo. METHODS: Eighty Lewis rats were randomized to eight groups (n = 10 for each group)...

A short-term exposure to resveratrol at high dosages exerts a remarkable cardioprotective effect. Whether a long-term exposure to resveratrol at low dosages that can be obtained through consumption of a resveratrol-rich diet is beneficial to heart diseases is unknown. We tested the effects of a resveratrol-enriched diet on cardiovascular remodeling of chronic heart failure (CHF) in rats resulting from permanent ligation of left coronary artery. Two weeks after surgery, rats were started on either a resveratrol-enriched (R; 5 mg/kg per day; n = 23) or normal (Control; n = 23) diet for next 10 months...

Acute myocardial infarction (AMI) is rare in young adults. We present a case of a 29-year-old black woman who presented with an acute onset of chest pain while sleeping. Anterior wall ST-elevation AMI was diagnosed based on clinical presentation, electrocardiographic findings, and elevated cardiac biomarkers. Coronary angiography revealed a totally occluded proximal left anterior descending artery. The obstructing lesion, thrombus, was removed. There was no evidence of atherosclerotic disease or dissection...
