Thrombolysis with intravenous tissue plasminogen activator (t-PA) is currently an approved therapy for patients with acute ischemic stroke. Acute myocardial infarction (AMI) immediately following t-PA treatment for stroke is a rare but serious complication. A case of acute myocardial infarction (MI) following IV t-PA infusion for acute stroke was observed. This is a 52-year-old male with a known history of hypertension and chest pain, who subsequently developed MI four hours after IV t-PA was administered for acute ischemic stroke. The disruption of intra-cardiac thrombus and subsequent embolization to the coronary arteries may be an important mechanism. In addition, spontaneous recanalization of infarct-related arteries may be associated with greater myocardial salvage and better prognosis.

BACKGROUNDPrevious studies revealed that culprit vessels of ST-segment elevation myocardial infarction (STEMI) were often related to mild or moderate stenosis. However, recent studies suggested that severe stenosis was primarily found in culprit lesions. The objective of this study was to analyze the stenosis severity of culprit lesions in STEMI patients and to clarify the paradoxical results.

METHODSA total of 489 consecutive STEMI patients who underwent primary percutaneous coronary intervention were retrospectively studied from January 2012 to December 2014. The patients were divided into three groups based on stenosis severity using quantitative coronary analysis: Group A, 314 cases, stenosis ≥70%; Group B, 127 cases, stenosis 50-70%; and Group C, 48 cases, stenosis ≤50%. The clinical, demographic, and angiographic data of all groups were analyzed.

RESULTSPatients in Group A exhibited a significantly higher prevalence of history of angina pectoris (95.9% vs. 62.5%, P< 0.001), multivessel disease (73.2% vs. 54.2%, P = 0.007), and lower cardiac ejection fraction (53.3 ± 8.6 vs. 56.8 ± 8.4, P= 0.009) than those in Group C. Multivariable analysis revealed that history of angina pectoris (odds ratio [OR]: 13.89, 95% confidence interval [CI]: 6.21-31.11) and multivessel disease (OR: 2.32, 95% CI: 1.25-4.31) were correlated with severe stenosis of the culprit lesion in Group A.

CONCLUSIONSMost culprit lesions in STEMI patients were severe stenosis. These patients exhibited a higher prevalence of angina history and multivessel diseases.

Cardiogenic unilateral pulmonary edema (UPE) is a rare clinical entity that is often misdiagnosed at first. Most cases of cardiogenic UPE occur in the right upper lobe and are caused by severe mitral regurgitation (MR). We present an unusual case of right-sided UPE in a patient with cardiogenic shock due to acute myocardial infarction (AMI) without severe MR. The patient was successfully treated by percutaneous coronary intervention and medical therapy for heart failure. Follow-up chest Radiography showed complete resolution of the UPE. This case reminds us that AMI can present as UPE even in patients without severe MR or any preexisting pulmonary disease affecting the vasculature or parenchyma of the lung.

We described two patients who were successfully resuscitated from out-of-hospital cardiac arrest. Their ECGs showed ST elevations in V1 and aVR, as well as diffuse ST depression. Their ST elevation in V1 was noted to be greater than in aVR. While one patient was found to have an occlusion of the right ventricular (RV) branch of the right coronary artery, the other was found to have an occlusion of a proximal non-dominant right coronary artery supplying the RV branch. Successful primary percutaneous coronary intervention was performed for each patient with angioplasty and implantation of a drug-eluting stent. Both patients made good physical and neurological recovery.

BACKGROUND/AIMS: The aim of this study was to compare the risk of complications and outcome between infarct-related artery (IRA)-only revascularization and multivessel (MV) revascularization in patients with acute myocardial infarction (MI) with renal insufficiency and MV disease. METHODS: A total of 1,031 acute MI patients with renal insufficiency and MV disease who were registered in the Korea Working Group on Myocardial Infarction were enrolled. They were divided into two groups (IRA-only revascularization group, n = 404; MV revascularization group, n = 627), and investigated the cumulative incidence of major adverse cardiac events (MACE) and the incidence of complications after percutaneous coronary intervention (PCI). RESULTS: Complications after PCI occurred in 19.9% of all patients (206/1,031). Complications after PCI occurred more frequently in the MV revascularization group compared with the IRA-only revascularization group (20.1% [126/627] vs. 15.3% [62/404], respectively; p = 0.029]. The overall in-hospital mortality rate was 6.3%, and there was no significant difference between the groups (5.2% in the IRA-only revascularization group vs. 7.0% in the MV revascularization group; p = 0.241). The total incidence of MACE was 11.1%, and there was no significant difference between the groups (11.6% in the IRA-only revascularization group vs. 10.7% in the MV revascularization group; p = 0.636). CONCLUSIONS: The incidence of complications after PCI was significantly lower in the IRA-only revascularization group compared with the MV revascularization group. However, there were no significant difference in the 12-month outcomes between groups in patients with acute MI and renal insufficiency with MV disease.

OBJECTIVETo improve the awareness of acute coronary artery thrombosis in Kawasaki disease (KD).

METHODSix KD patients with acute coronary artery thrombosis (Jan. 2004 to Jan. 2013) were studied retrospectively. The basic information, clinical manifestations, laboratory data, echocardiography and electrocardiography (ECG), method and consequence of thrombolytic therapy were analyzed.

RESULTThe mean age of patients with coronary artery thrombosis (5 males and 1 female) was (17.2 ± 11.3) months.Five cases had thrombosis in left coronary artery (LCA), and four cases had thrombosis in aneurysm of left anterior descending artery (LAD). One case had thrombosis in both left and right coronary artery (RCA).One case died. Maximum thrombus was about 1.60 cm × 0.80 cm, locating in LAD. The diameter of LCA and RCA was (0.44 ± 0.07) cm and (0.45 ± 0.07) cm. Two patients showed abnormal ECG. Case 3 showed ST segment depression in lead V5. Case 6 showed myocardial infarction.In acute phase of KD, three patients received treatment with intravenous immunoglobin (IVIG), five patients were treated with aspirin.In sub-acute and convalescent phase of KD, all patients were treated with low-dose aspirin.Warfarin and dipyridamole were applied in 5 patients. All cases were treated with thrombolytic therapy using urokinase and/or heparin. After thrombolytic therapy, echocardiography showed thrombolysis in four cases and no change in one.One patient died of myocardial infarction.

CONCLUSIONMost of acute coronary thrombosis in KD occurred in LAD. KD patients with coronary artery thrombosis are at risk of sudden death due to myocardial infarction.

BACKGROUND/AIMS: A controversy exists about which statin is preferable for patients with acute myocardial infarction (AMI), and clinical impacts of different statins according to lipophilicity have not been established. METHODS: The 1,124 patients with AMI included in the present study were divided into hydrophilic- and lipophilic-statin groups. In-hospital complications (defined as death, cardiogenic shock, ventricular arrhythmia, infection, bleeding, and renal insufficiency, and other fatal arrhythmias), major adverse cardiac events (MACE), all-cause death, re-myocardial infarction, re-percutaneous coronary intervention (re-PCI), and surgical revascularization were analyzed during a 1-year clinical follow-up. RESULTS: Baseline characteristics were similar between the two groups, and in-hospital complication rates showed no between-group differences (11.7% vs. 12.8%, p = 0.688). Although MACE at the 1- and 6-month clinical follow-ups occurred more in hydrophilic statin group I (1 month: 10.0% vs. 4.4%, p = 0.001; 6 month: 19.9% vs. 14.2%, p = 0.022), no significant difference in MACE was observed at the 1-year follow-up (21.5% vs. 17.9%, p = 0.172). Both statin groups showed similar efficacy for reducing serum lipid concentrations. A Cox-regression analysis showed that the use of a hydrophilic statin did not predict 1-year MACE, all-cause death, AMI, or re-PCI. CONCLUSIONS: Although short-term cardiovascular outcomes were better in the lipophilic-statin group, 1-year outcomes were similar in patients with AMI who were administered hydrophilic and lipophilic statins. In other words, the type of statin did not influence 1-year outcomes in patients with AMI.
