A 14-year-old male patient with a history of atypical Kawasaki disease at age 2 presents with triple vessel giant coronary aneurysms. Over the last several years, he began experiencing angina and dyspnea on exertion, which was a result of fully occluded right coronary and left circumflex arteries and 90% stenosis in the left anterior descending artery. He underwent off-pump coronary artery bypass using the left and right internal mammary arteries. At 18-month follow-up, there is no evidence of ischemia. Off-pump bypass is a feasible option for surgical management of the stenotic and occlusive complications of Kawasaki disease...

OBJECTIVES: The aim of this study was to assess the feasibility and clinical results following a pre-specified bioresorbable scaffold (Absorb BVS) implantation strategy in patients with ST-segment elevation myocardial infarction (STEMI). BACKGROUND: Concerns were raised about the safety of Absorb because a non-negligible rate of thrombosis was reported within 30 days and at midterm follow-up after primary percutaneous coronary intervention. METHODS: This was a prospective, multicenter study of patients with STEMI (<75 years of age with symptom onset <12 h) undergoing primary percutaneous coronary intervention with Absorb following a dedicated implantation protocol...

OBJECTIVE: Invasive coronary angiography remains the cornerstone for evaluation of coronary stenoses despite there being a poor correlation between luminal loss assessment by coronary luminography and myocardial ischemia. This is especially true for coronary lesions deemed moderate by visual assessment. Coronary pressure-derived fractional flow reserve (FFR) has emerged as the gold standard for the evaluation of hemodynamic significance of coronary artery stenosis, which is cost effective and leads to improved patient outcomes...

Matrix metalloproteinase-2 (MMP-2) mediated degradation of myosin light chain 1 (MLC1) and troponin I (TnI) contributes to myocardial ischemia/reperfusion (I/R) injury. Modifications of MLC1 triggered by oxidative stress are mediated by myosin light chain kinase (MLCK), nitric oxide synthase (NOS), and MMP-2. Previous studies have shown that inhibiting both MLCK and MMP-2 protects against I/R injury. Here, we hypothesized that the addition of NOS inhibitor (L-NAME) at subprotective concentration to the mixture of subprotective concentrations of ML-7 and doxycycline (Doxy), will increase a synergistic cardioprotection of Doxy and ML-7 during I/R...

The aim of this study is to investigate both the efficacy and mechanism of action of kaempferide (Kae) as a therapy for the treatment of cardiovascular disease. A rat model of myocardial ischemia/reperfusion (I/R) injury was established by ligation of the left anterior descending coronary artery for 30 min followed by a 2 h perfusion. In our study, we show that Kae remarkably improved cardiac function, alleviated myocardial injury via a decrease in myocardial enzyme levels, and attenuated myocardial infarct size in a dose-dependent manner...

BACKGROUND: A specific ECG pattern of presentation of ST-segment elevation acute myocardial infarction (STEMI), characterized by "triangular QRS-ST-T waveform" (TW), has been associated with poor in-hospital prognosis but longitudinal data on its incidence and clinical impact are lacking. We prospectively evaluated the incidence and prognostic meaning of the TW pattern in a cohort of consecutive STEMI patients. METHODS: All STEMI patients who presented within 12h of symptoms onset and showed no complete bundle branch block or paced ventricular rhythm were included...

Invasive coronary angiography (ICA) with measurement of fractional flow reserve (FFR) by means of a pressure wire technique is the established reference standard for the functional assessment of coronary artery disease (CAD) ( 1 , 2 ). Coronary computed tomographic (CT) angiography has emerged as a noninvasive method for direct assessment of CAD and plaque characterization with high diagnostic accuracy compared with ICA ( 3 , 4 ). However, the solely anatomic assessment provided with both coronary CT angiography and ICA has poor discriminatory power for ischemia-inducing lesions...

Intramural coronary arteries in patients with d-transposition of the great arteries (d-TGA) usually arise from the opposite sinus of Valsalva and traverse horizontally across the posterior/facing commissure before emerging externally from the appropriate sinus of Valsalva. Failure to make appropriate technical modifications during coronary transfer can result in an important risk of posttransfer ischemia. We report a case with an unusual course of an intramural left anterior descending (LAD) coronary artery in a patient with d-TGA, with origin at the mid ascending aorta and a vertical intramural course, increasing the susceptibility to injury during an arterial switch operation (ASO)...

BACKGROUND: Most patients presenting to the emergency department (ED) with suspected acute coronary syndrome (ACS) undergo noninvasive cardiac testing with a low diagnostic yield. We determined whether a combination of high-sensitivity cardiac troponin I (hs-cTnI) and cardiovascular risk factors might improve selection of patients for cardiac testing. METHODS: We included patients from the Rule Out Myocardial Infarction/Ischemia Using Computer Assisted Tomography (ROMICAT) I and II trials who presented to the ED with acute chest pain and were referred for cardiac testing...

BACKGROUND The aim of this study was to investigate the role of tilianin in modulating mitochondrial functions and mitochondria-mediated apoptosis during cardio-protection. MATERIAL AND METHODS Myocardial ischemia/reperfusion (I/R) injury was induced by 30 minutes coronary occlusion followed by two hours reperfusion in Sprague-Dawley rats. To investigate the cardio-protective effects of tilianin, apoptosis was evaluated by TUNEL. Mitochondrial ultrastructure and function were assessed by transmission electron microscopy, dynamics of mitochondrial permeability transition pore (mPTP) opening and ATP production in the myocardium; Ca2+ content and reactive oxygen species (ROS) were measured to evaluated the level of damage factors in the mitochondria...

BACKGROUND: Nitric oxide (NO) is an effective mediator of ischemic preconditioning (IPC)-induced cardioprotection. Atrial natriuretic peptide (ANP) is downregulated after ovariectomy, which results in reduction in the level of NO. The present study deals with the investigation of the role of ANP in abrogated cardioprotective effect of IPC in the ovariectomized rat heart. METHODS: Heart was isolated from ovariectomized rat and mounted on Langendorff's apparatus, subjected to 30 min of ischemia and 120 min of reperfusion...

BACKGROUND: Autonomic regulation therapy involving either vagus nerve stimulation (VNS) or spinal cord stimulation (SCS) represents emerging bioelectronic therapies for heart disease. The objective of this study was to determine if VNS and/or SCS modulate primary cardiac afferent sensory transduction of the ischemic myocardium. METHODS: Using extracellular recordings in 19 anesthetized canines, of 88 neurons evaluated, 36 ventricular-related nodose ganglia sensory neurons were identified by their functional activity responses to epicardial touch, chemical activation of their sensory neurites (epicardial veratridine) and great vessel (descending aorta or inferior vena cava) occlusion...

BACKGROUND: Blockage of a coronary artery, usually caused by arteriosclerosis, can lead to life threatening acute myocardial infarction. Opening with PCI (percutaneous coronary intervention), may be lifesaving, but reperfusion might exacerbate the cellular damage, and changes in the endothelium are believed to be involved in this worsened outcome. AIM: The aim of the present study was to compare endothelial dependent and independent vasodilatory effect after experimental myocardial ischemia/reperfusion (I/R)...

The popularization of genome-wide analyses and RNA sequencing led to the discovery that a large part of the human genome, while effectively transcribed, does not encode proteins. Long non-coding RNAs have emerged as critical regulators of gene expression in both normal and disease states. Studies of long non-coding RNAs expressed in the heart, in combination with gene association studies, revealed that these molecules are regulated during cardiovascular development and disease. Some long non-coding RNAs have been functionally implicated in cardiac pathophysiology and constitute potential therapeutic targets...

Mental stress-induced myocardial ischemia is common and a prognostic factor of adverse cardiovascular outcomes in patients with coronary artery disease (CAD). The present study aimed at examining associations between mental stress-induced myocardial annular velocity (MAV) and cardiovascular outcome in patients with CAD. MAV, specifically, diastolic early (e'), diastolic late (a'), and systolic (s') velocities were obtained at rest and during mental stress testing in 224 patients with clinically stable CAD. Using Cox regression models, age, sex, and baseline-adjusted mental stress-induced MAV measures were examined as predictors of a priori defined composite event term that comprised all-cause mortality and/or nonfatal cardiovascular events, resulting in an unplanned hospitalization (major adverse cardiovascular events [MACE])...

REVIEW
Shams Y-Hassan, Per Tornvall
Takotsubo syndrome is a recently recognized acute cardiac disease entity with a clinical presentation resembling that of an acute coronary syndrome. The typical takotsubo syndrome patient has a unique circumferential left (bi-) ventricular contraction abnormality profile that extends beyond a coronary artery supply territory and appears to follow the anatomical cardiac sympathetic innervation. The syndrome predominantly affects postmenopausal women and is often preceded by emotional or physical stress. Patients with predisposing factors such as malignancy and other chronic comorbidities are more prone to suffer from takotsubo syndrome...

The association between body mass index (BMI) and major clinical events after acute coronary syndrome (ACS) remains controversial. We investigated the impact of BMI on major clinical events after ACS in a large individual patient data meta-analysis. Data on 81,553 patients from 45 different countries with ACS enrolled in 8 large randomized clinical trials were included, followed up for a median of 171 days. The mean age was 63.4 ± 11.7, 70% were male, and the mean BMI was 27.3 ± 4.7 kg/m(2). Compared with upper-normal-weight participants (BMI 21...

BACKGROUND: There is limited knowledge on the residual risk of cardiovascular death (CVD) in patients with stable coronary artery disease (CAD) who receive modern secondary prevention. Our aim was to analyze the causes of death and to determine predictors of CVD in the 5-year CORONOR registry. METHODS: We studied 4184 consecutive CAD outpatients who were free from any myocardial infarction (MI) or coronary revascularization for more than 1 year at inclusion. Antithrombotics were prescribed in 99%, statins in 92%, inhibitors of renin-angiotensin system in 82%, and β-blockers in 79%; 86% had prior coronary revascularization...
