Thrombosis is a major complication of polycythemia vera (PV) and also a well-known complication of thalassemia. We reported a case of non-atherosclerotic ST-segment elevation myocardial infarction (STEMI) in a 17- year-old man with concurrent post-splenectomized hemoglobin H-Constant Spring disease and <em>JAK2</em> V617F mutation-positive PV. The patient initially presented with extreme thrombocytosis (platelet counts greater than 1,000,000/μL) and three months later developed an acute STEMI. Coronary artery angiography revealed an acute clot in the right coronary artery without atherosclerotic plaque. He was treated with plateletpheresis, hydroxyurea and antiplatelet agents. The platelet count decreased and his symptoms improved. This case represents the importance of early diagnosis, awareness of the increased risk for thrombotic complications, and early treatment of PV in patients who have underlying thalassemia with marked thrombocytosis.

Background and Aims: Diabetic patients are at increased risk of developing coronary artery disease. This study was conducted with the aim to compare the extent and severity of coronary artery disease in patients with and without diabetes presenting with non ST segment elevation myocardial infarction (NSTEMI). Methods: This was a single center, hospital based, cross sectional, observational comparative study in which total 172 patients presenting with NSTEMI were divided into two groups of 86 patients each based on presence or absence of diabetes mellitus. Demographic, laboratory and angiographic data were analysed and compared between two groups. Results: Among 86 patients enrolled in each group demographic characteristics and risk profile were not significantly different except for smoking status. Significant number of non-diabetics were current smoker (26.7% vs. 9.3%; p < 0.01). Hypertension was the most common risk factor in both groups. Non-diabetic patients had significantly high single vessel disease when compared to diabetics (11.6% vs 24.4%; p=0.03) while multivessel disease was significantly higher among diabetics (80.2% vs 59.3%; p<0.01). Diabetics had severe coronary artery disease with significantly high Gensini score (71.18±39.03 vs 59.84±33.68; p=0.04). There was no difference in terms of type of vessel affected. Conclusions: Diabetic patients presenting with NSTEMI are likely to have more severe and extensive coronary artery disease compared to non-diabetic patients.

Simultaneous ST-segment elevation (SST-SE) in anterior and inferior leads in the setting of ST-segment elevation myocardial infarction is often confounding for a cardiologist and further more challenging is the angiographic localization of the culprit vessel. SST-SE can be fatal as it jeopardizes simultaneously a larger area of myocardium. This phenomenon could be due to “one lesion, one artery,” “two lesions, one artery,” “two lesions, two arteries,” or combinations in two different coronary arteries. We have discussed an index case where we encountered a phenomenon of SST-SE and coronary angiography demonstrated “two lesions, one artery” (proximal occlusion and distal critical diffuse stenoses of the wrap-around left anterior descending [LAD] artery) and “two lesions, two (different coronary) arteries” (previously mentioned stenoses of the LAD artery and critical stenosis of the posterolateral branch of the right coronary arteries). We have also described in brief the possible causes of this phenomena and their electroangiographic correlation of the culprit vessels.

Drugs that work on the hematologic system play an important role in helping to limit the morbidity and mortality that can be associated with an acute coronary syndrome. The pharmacology of the fibrinolytic agents, thrombin inhibitors, and antiplatelet agents is described. A case study of a woman having an ST-segment elevation myocardial infarction is reviewed to highlight the importance of drugs that work on the hematologic system.

Patients with coronary artery disease (CAD) present clinically when their disease enters an unstable phase known as an acute coronary syndrome (ACS), in which the cap of a previously stable atheromatous coronary plaque ruptures or erodes, which in turn activates a thrombotic cascade that may lead to coronary artery occlusion, myocardial infarction (MI), cardiogenic shock, and patient death. There are nearly 2 million episodes of ACS in the United States annually; it is the most common reason for hospitalization with CAD and is the leading cause of death in the developed world. ACS patients include those with unstable angina (UA), non–ST segment elevation myocardial infarction (non-STEMI), and ST segment elevation myocardial infarction (STEMI) and patients who die suddenly of an arrhythmia precipitated by coronary occlusion. The distinction among various ACS subgroups reflects varying characteristics of clinical presentation (presence or absence of elevated cardiac biomarkers) and the type of electrocardiographic (ECG) changes manifested on the initial ECG at the time of hospitalization. This chapter focuses on UA and non-STEMI. A graph outlines mortality risks faced by patients with varying degrees of renal insufficiency. An algorithm describes the suggested management of patients admitted with UA or non-STEMI. Tables describe the risk stratification of the patient with chest pain, categories of Killip class, examination findings of a patient with high-risk ACS, diagnosis of MI, causes of troponin elevation other than ischemic heart disease, initial risk stratification of ACS patients, and long-term medical therapies and goals in ACS patients. This review contains 2 highly rendered figures, 11 tables, and 76 references.
