Acute myocardial infarction associated with myocardial bridging: a case report

We describe a case of a 41-year-old woman with chest pain for 1 hour who was admitted to our emergency room with acute myocardial infarction. Coronary angiography and spiral computer tomography showed myocardial bridging and an intracoronary thrombus in the mid-segment of the left anterior descending artery. She felt better after taking aspirin, diltiazem and a beta blocker and was discharged 15 days later.     

Acute myocardial infarction associated with coronary spasm in a young man

CASE REPORT Acute myocardial infarction(AMI) is usually caused by atherosclerotic plaque disruption and thrombus formation.However,AMI is occasionally caused by coronary spasm too.We are reporting a case with AMI due to coronary spasm whose serial electrocardiogram(ECG) showed dynamic changes of T waves in precordial leads.     

Acute myocardial infarction associated with small-size lung cancer in a young woman

A 34-year-old woman visited our hospital with chest pain and was diagnosed with acute myocardial infarction (AMI) on admission. Echocardiography imaging revealed the presence of complex masses in the aortic valve. As serum tumor marker CA19-9 was elevated, she was screened for malignant disease. A computed tomography (CT) scan revealed a solitary pulmonary nodule, but because the nodule was small and non-specific, CT follow-up was considered appropriate. However, she developed hemorrhagic stroke in the short term and was subsequently diagnosed with lung adenocarcinoma. Clinicians should be on alert for the occurrence of AMI in patients with small-size lung cancer.     

Myocardial infarction in a young African-American male due to myocardial bridging

Myocardial bridging is a clinically uncommon congenital anomaly characterized by tunneling of the coronary artery within the myocardial tissue, usually seen in the left anterior descending artery. Myocardial bridging is associated with altered intracoronary hemodynamics during systole and diastole, determined by the severity and the location of the bridging within the coronary artery. Patients with myocardial bridging may present with angina in the absence of other coronary risk factors which may paradoxically improve with exercise due to an increased intrasystolic pressure, preventing vessel compression. It is uncommon to have bridging in the right coronary artery; it is even more uncommon to have right coronary artery bridging with angina and significant ECG changes. We present a case involving bridging of the right coronary artery with significant symptoms and ECG changes.     

Acute myocardial infarction associated with pregnancy

Acute myocardial infarction (AMI) during pregnancy or the early post-partum period is rare but has been shown to be associated with poor maternal as well as fetal outcome. Major changes in both diagnosis and treatment of AMI in the nonpregnant patient have lead to improved outcome which may also affect pregnant patients. The purpose of this paper is to review available information related to the pathophysiology and clinical profile and provide recommendations for the diagnosis and management of AMI occuring during pregnancy and the early post-partum period.     

Acute myocardial infarction in a young female with familial hyperbetalipoproteinemia.

A young woman, 21 years of age, suffered an acute transmural inferior wall myocardial infarction. EKG changes and serum enzymes accompanied a typical history. Coronary angiography perfomed 2 months after the acute episode showed complete occlusion of the right coronary artery and some mild disease of the circumflex and left anterior descending branches. Family history of type II hyperlipoproteinemia was present and she was known to have cholesterol since she was 12 years of age.     

Acute myocardial infarction in a young woman with severe ulcerative colitis

In this report we present a case of a 28-year-old woman who was admitted to our emergency room complaining of chest pain. Her clinical ECG and biochemical evaluation was consistent with acute nonatherogenic myocardial infarction. Subsequent work is revealed that she was suffering from ulcerative colitis with acute exacerbation since last week. We discussed triggering factors for thrombogenic and inflammatory tendency of patient with comprehensive review of literature to clarify the causal relationship.     

Acute inferior myocardial infarction in a young female patient with polyarteritis nodosa

Coronary involvement of polyarteritis nodosa (PAN) has been mostly identified in postmortem studies. We report a case with inferior myocardial infarction (MI) because of coronary dissection and thrombosis in PAN. A 23-year-old woman with chest pain was admitted to the emergency department. The admission ECG was suggestive of inferior MI with no right ventricular infarction. Coronary angiography revealed an occluded right coronary artery because of coronary dissection and concomitant thrombosis. Coronary angioplasty and stent implantation were performed successfully without complications. This report emphasizes the importance of PAN in spontaneous coronary dissection and thrombosis even in young patients.     

Acute myocardial infarction in a young man complicated with left ventricular thrombi

Premature coronary artery disease is very rare and complication with thrombus formation in the left ventricle is rarer still. A 23-year-old man was admitted to hospital for recent acute myocardial infarction after being struck by a basketball eight days previously. Echocardiography identified two peduncle thrombi at the apex of the left ventricle, which were confirmed with computed tomography. The proximal left anterior descending coronary artery was totally occluded. Following two weeks of treatment with heparin and warfarin, the patient agreed to undergo a coronary artery bypass graft and thrombectomy. The ecchymosed tissue around the coronary artery implied that a trauma injury might have been the cause of the coronary artery disease in this case. This work reviews the pathophysiology and natural history of coronary artery disease in a case of very young myocardial infarction.     

Acute myocardial infarction in a young man using anabolic steroids

Anabolic-androgenic steroids are used worldwide to help athletes gain muscle mass and strength. Their use and abuse is associated with numerous side effects, including acute myocardial infarction (MI). We report a case of MI in a young 31-year-old bodybuilder. Because of the serious cardiovascular complications of anabolic steroids, physicians should be aware of their abuse and consequences.
