Myocardial infarction secondary to unintentional ingestion of hydrogen peroxide

Ingestion of acid-containing household products, either accidentally or as a suicide attempt, is a common form of intoxication. A clear and odorless liquid, hydrogen peroxide is an oxidizing agent found in most households and many industrial environments. Cardiovascular manifestations of hydrogen peroxide ingestion are extremely rare. Here we report a 60 year-old woman with acute inferolateral myocardial infarction (MI) after hydrogen peroxide ingestion, who had no history of coronary artery disease. Physicians dealing with hydrogen peroxide ingestion in the emergency department should be aware of the probability of MI and obtain an electrocardiogram, even if the patient has no cardiac complaint.

Twin Circumflex Arteries with Left Sinus of Valsalva Origin: A Case Report

Coronary artery anomalies are not uncommon. The importance of coronary anomalies varies from unimportant to life threatening. Herein, we report for the first time twin circumflex coronary arteries originating separately from the left sinus of Valsalva

Myocardial perfusion scintigraphy fi ndings in patients with mild coronary atherosclerotic lesions on coronary angiography

Objectives: Myocardial perfusion scintigraphy (MPS) iswidely used in functional assessment of myocardial per-fusion. But, some study results are in contradiction withseverity of coronary artery disease detected by coronaryangiography (CA). It is frequently encountered case thatCA is completely normal whereas MPS describes isch-emia. In this study, we aimed to investigate whether mildatherosclerotic lesions cause ischemia.Materials and methods: MPS with 99mTc-MIBI was per-formed in 52 patients who applied to cardiology clinics forhistory of chest pain and underwent diagnostic CA within3 months.Results: In 22 of 52 patients with mild atherosclerotic le-sions, ischemia in various degrees was detected on MPS.In statistical analysis, any signifi cant relationship was notfound between ischemia and gender, hypertension, DM,dyslipidemia, smoking, mitral valve insuffi ciency, left ven-tricular hypertrophy, exercise testing result and affectedcoronary artery.Conclusion: Our study fi ndings have shown that mild ath-erosclerotic lesions even at very early stage may causemyocardial ischemi

Red cell distribution width as a novel prognostic marker in patients undergoing primary angioplasty for acute myocardial infarction

Objectives Red cell distribution width (RDW), a measure of red blood cell size heterogeneity, was evaluated in patients undergoing primary percutaneous coronary intervention (PCI) for ST-segment elevation myocardial infarction (STEMI)
