Isolated Right Ventricular Infarction Mimicking Anterior ST-Segment Elevation.

Acute coronary syndromes in patients with presence of ST-segment elevation in the anterior precordial leads indicates left anterior descending coronary artery occlusion. However, anterior ST-segment elevation has also been described in right ventricular myocardial infarction and is thought to be due to right coronary artery (RCA) occlusion. We present a rare case of isolated RVMI presenting with anterior ST-segment elevation due to proximal occlusion of a right coronary artery that was treated by primary coronary angioplasty.

A Rare Case of Type IV Dual Left Anterior Descending Coronary Artery.

Coronary artery anomalies are usually asymptomatic and associated with other cardiac malformations. Dual left anterior descending coronary artery (LAD) is an uncommon congenital anomaly with four subtypes. This anomaly has been described in the angiographic literature and dual LAD types depending on the origin of major septal and diagonal branches and course within the anterior interventricular sulcus.

Heart rate turbulence in patients with stable coronary artery disease and its relationship with the severity of the disease.

Objective: Heart rate turbulence (HRT) indicates the impairment of cardiac autonomic function. With the literature containing insufficient information on HRT in stable coronary artery disease (CAD), this study aimed to investigate the role of HRT in patients with stable CAD.

Methods: The study included 58 patients (mean age: 58.

Comparison of Long-Term Outcomes in Real-World Patients Between Resolute Zotarilumus-Eluting and Paclitaxel-Eluting Stents in Small Vessel.

Objective: To compare the long-term clinical outcomes between Resolute zotarolimus-eluting stent (R-ZES) and paclitaxel-eluting stent (PES) in patients with small coronary artery disease.

Background: Patients with a small vessel diameter are independently associated with increased risk of adverse cardiac events after drug-eluting stent implantation.

Methods: A cohort of 265 patients treated with R-ZES (185 patients with 211 lesions) or PES (80 patients with 100 lesions) in small vessel (≤2.

Impact of Rosuvastatin on contrast-induced acute kidney injury in patients at high risk for nephropathy undergoing elective angiography.

Although statins have been shown to prevent contrast-induced acute kidney injury in patients with acute coronary syndromes, the benefit of statins is not known for patients at high risk for nephropathy who undergo elective coronary angiography. Two hundred twenty consecutive statin-naive patients with chronic kidney disease (estimated glomerular filtration rate <60 ml/min/1.73 m(2)) who underwent elective coronary or peripheral angiography were randomly assigned to receive rosuvastatin (40 mg on admission, followed by 20 mg/day; n = 110) or no statin treatment (control group, n = 110).

P-wave dispersion and its relationship with the severity of the disease in patients with stable coronary artery disease.

Objective: P- wave dispersion (PD) is an indicator of inhomogeneous and discontinuous propagation of sinus impulses. In the present study we aimed to investigate the PD and its association with the severity of the disease. in patients with stable coronary artery disease.

Relationship between serum endothelin-1 level and spontaneous reperfusion in patients with acute myocardial infarction.

Aim: Spontaneous reperfusion (SR) was associated with better clinical outcomes and lower incidence of major adverse cardiovascular events. Endothelin-1 (ET-1) is a potent endothelium-derived vasoconstrictor peptide and elevated systemic ET-1 levels predict a poor prognosis in patients with ST-segment elevation myocardial infarction (STEMI). We aimed to investigate the relationship between systemic ET-1 plasma levels and SR in a group of STEMI patients treated with a primary percutaneous coronary intervention (PCI).

Relationship between increased serum resistin level and severity of coronary artery disease.

Resistin, which is derived from the gene of RSTN, belongs to a family of cysteine-rich secretory proteins called resistin-like molecules (RELMs). Increased serum resistin levels are associated with coronary artery disease (CAD) and the risk of cardiovascular death. Patients (n = 214) with an initial diagnosis of stable angina pectoris, unstable angina pectoris, and myocardial infarction without ST-segment elevation and referred to catheter laboratory for coronary angiography were enrolled in the study.

Percutaneous coronary intervention vs. optimal medical therapy--the other side of the coin: medication adherence.

What Is Known And Objective: Although many studies have examined medication adherence in patients with coronary artery disease (CAD), no prospective trial has compared medication adherence between patients treated with percutaneous coronary intervention (PCI) or with optimal medical therapy (OMT) in real life. This study sought to compare the adherence to evidence-based secondary preventive medications in patients with documented CAD treated with PCI and OMT, or OMT alone.

Methods: We evaluated adherence to statins, beta-blockers, and angiotensin converting enzyme inhibitors (ACEI) during a 6-month follow-up in 232 patients with documented CAD, comparing patients treated with PCI and those receiving medical therapy alone.

Giant thrombus on apical wall of left ventricle due to HIT syndrome after anterior MI.

Heparin-induced thrombocytopenia (HIT) is the most important and the most frequent drug-induced, immune-mediated type of thrombocytopenia. It is associated with significant mortality and morbidity if unrecognized. We describe a patient with a giant thrombus on the apical wall of the left ventricle that occurred due to HIT syndrome after anterior myocardial infarction.

Follow-up of aspirin-resistant patients with end-stage kidney disease.

Background: Aspirin resistance is defined by platelet function testing and presumed clinical unresponsiveness to aspirin. Aspirin-resistant patients are at a greater risk of clinically important adverse cardiovascular events. We aimed to investigate whether end-stage renal disease patients with aspirin resistance are at increased risk for long-term major adverse clinical events.

Pulmonary arteriovenous fistula coexisting with secundum atrial septal defect. An unusual cause of stroke in a young woman.

Pulmonary arteriovenous malformations (PAVM) consist of an abnormal connection between the pulmonary artery and vein bypassing the pulmonary capillary bed. Pulmonary arteriovenous fistulae are characterized by a right-to-left shunt of variable magnitude, and they may be accompanied by other congenital anomalies. We describe a case of pulmonary arteriovenous fistula with a secundum type atrial septal defect (ASD) in a 38-year-old woman, who underwent successful transcatheter closure of both the ASD and PAVM.

Admission hyperglycemia and TIMI frame count in primary percutaneous coronary intervention.

We evaluated the relationship between admission blood glucose levels and estimated coronary flow by the thrombolysis in myocardial infarction (TIMI) frame count (TFC) method in patients with ST-segment elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (pPCI). The TFC of 121 consecutive patients with STEMI were evaluated after pPCI. Patients with admission glucose levels > 198 mg/dL (11 mmol/L) were defined as hyperglycemic.

Laboratory signs of aspirin response in haemodialysis patients.

Introduction: Aspirin is effective in the secondary prevention and high-risk primary prevention of cardiovascular events. However, clinical and laboratory evidence demonstrates diminished or no response to aspirin in some patients. This study was designed to assess aspirin response in haemodialysis patients.

Concurrent pulmonary embolism and acute coronary syndrome with dynamic electrocardiographic changes.

Concomitant occurrence of pulmonary embolism and acute coronary syndrome is rare. The early diagnosis and treatment of acute coronary syndrome with right ventricular myocardial ischemia during acute pulmonary embolism (APE) are crucial. The irreversible right ventricular myocardial dysfunction is a major risk factor for mortality from APE.

Correlation between the AHCPR (Agency For Health Care Policy and Research) risk stratification and angiographic morphology in non-ST-segment elevation acute coronary syndrome.

Objectives: Risk stratification in acute coronary syndromes is an important diagnostic tool guiding future therapy. We evaluated the correlation between the AHCPR (Agency for Health Care Policy and Research) risk classification and angiographic morphology in patients with non-ST-segment elevation acute coronary syndrome (NSTE-ACS).

Study Design: A total of 163 patients hospitalized with the diagnosis of NSTE-ACS were prospectively enrolled.

The relationship between chronic kidney disease and SYNTAX score.

Chronic kidney disease (CKD) is associated with increased risk of cardiovascular disease and death. We evaluated the association between CKD and severity of coronary artery stenosis by calculating SYNTAX Score in patients with left main coronary artery and/or 3-vessel coronary artery disease. Coronary angiograms of 217 patients were assessed.

Retained pericardial pellets for 25 years: a case report.

Retained cardiac pellets are clinically silent foreign bodies that do not cause any cardiovascular disturbance. A 71-year-old woman presented with exertional chest pain. Her physical examination and surface electrocardiogram were normal.

Congenital absence of the left circumflex coronary artery and an unusually dominant course of the right coronary artery.

Congenital absence of the left circumflex artery (LCX) is a very rare congenital anomaly of the coronary circulation, and only a few cases have been reported in the literature. We report on a 55-year-old female with atypical chest pain. Routine coronary angiography showed a normal left anterior descending coronary artery (LAD), no LCX and a dominant right coronary artery (RCA), which continued beyond the crux, running the full course of the LCX and terminating in the left atrial branch.

Intravascular radiation therapy with a Re-188 liquid-filled balloon in patients with in-stent restenosis.

Objective: The aim of this study was to evaluate the feasibility and safety of intravascular radiation therapy (IVRT) using Re-188 filled balloon system in patients with in-stent stenosis.

Methods: A total of 39 patients with in-stent restenosis were enrolled as the IVRT (22 patients) and control groups (17 patients) of this study after a successful coronary angioplasty. For irradiation the angioplasty balloon was replaced by a noncompliant balloon of the same diameter but 10 mm longer in length with a proximal and distal radio-opaque marker to deliver the dose of 18 Gy at 0.

Recurrent thrombotic RCA occlusions due to exaggerated stent protrusion into the aorta.

We report a case with exaggerated stent protrusion from the right coronary ostium into the aorta leading to recurrent inferoposterior and right ventricular myocardial infarctions due to stent thrombosis, which were treated successfully with fibrinolysis. The stent was removed via transverse aortotomy and two bypass grafts were performed. Stents protruding from the aorta may not only cause technical difficulties but also carry a high risk of thrombosis.
