BACKGROUND AND OBJECTIVES: Carotid intima-media thickness (IMT) has been associated with an increased risk of ischemic stroke. To better understand this association, we evaluated the relationships of vascular risk factors, including carotid IMT and carotid plaque, and large territory cerebral infarction and small vessel stroke. SUBJECTS AND METHODS: A total of 502 patients with acute ischemic stroke were divided into two groups according to neurologic examinations and imaging studies; 1) a large territory infarction group (group I: n=126, 64.4+/-11 years, 78 males) and 2) a small vessel stroke group (group II: n=376, 62.5+/-11 years, 242 males). We evaluated associations between (a) territory and non-territory strokes and (b) age, sex, potential vascular risk factors, carotid image and cardiac function (by echocardiography). RESULTS: We did not find significant between group differences of age, sex, diabetes, previous history of ischemic stroke, plaque (presence, site and size of carotid plaque), and velocity of carotid blood flow and left ventricle ejection fraction. However, group I had a higher incidence of hypertension (p=0.006), smoking (p=0.003), and dyslipidemia (p=0.001). Group I had thicker carotid IMT than group II (right carotid: 0.81+/-0.21 mm vs. 0.76+/-0.19 mm, p=0.035; left carotid: 0.88+/-0.23 mm vs. 0.80+/-0.20 mm, p=0.014) and a higher e/e' level (12.08 vs. 9.66, p<0.001). Dyslipidemia, thicker carotid IMT and elevated E/E' ratios were significant independent predictors for large territory infarction in patients with ischemic stroke. CONCLUSION: Carotid IMT is significantly increased in patients with large territory infarction compared with those with small vessel stroke.

In this report, we describe a case of previous undiagnosed masses of the pulmonary valve mimicking infective endocarditis that were incidentally found during the work-up of a 62-year-old woman, who was presented with abdominal discomfort and dyspepsia. The pathologic findings were characteristics of a papillary fibroelastoma. Although benign, papillary fibroelastomas have the potential to cause lethal embolic events such as stroke, myocardial infarction, and pulmonary embolism are reported in some cases. Tumor identification and surgical excision are important to prevent such complications.

Myocardial abscess, a rare and life-threatening disease, occurs as a complication of infective endocarditis, acute myocardial infarction, or other infections in the setting of debilitating condition. We report a case of myocardial abscess mimicking acute myocardial infarction (AMI), not a following consequence of AMI. We can diagnose the disease with the aid of transthoracic echocardiography and cardiac computed tomography.

BACKGROUND: Atherosclerotic plaques in the carotid artery have been considered a potential source of cerebrovas- cular events. Carotid plaques are associated with an increased risk of ischemic stroke. We performed this study to evaluate the relationship between atherosclerotic carotid plaques and cardiac function measured by echocardiography in elderly patients with ischemic stroke. METHODS: A total of 415 patients aged >60 yrs with acute ischemic stroke were divided into two groups according to the presence(groups I, n=195, 140 males) or absence(group II, n=220, 112 males) of carotid plaques. We evaluated the asso ciation of the presence of plaques with age, sex, potential vascular risk factors, other carotid images, and cardiac function by echocardiography. RESULTS: Of the 415 patients, carotid plaques were found in 195 cases. Mean plaque size was 2.44+/-0.7mm on the right side and 2.32+/-0.75mm on the left. Plaques were located more frequently in the carotid bulb(68%) than in the common carotid artery(32%). 57% were calcified plaques and 72%, multiple plaques. Group I(with carotid plaques) had a significantly higher percentage of males(73.6%, p<0.001), hypertension(68.5%, p=0.043), diabetes(28.7%, p=0.029), and dyslipidemia(60.1%, p=0.008). In addition, group I had thicker carotid IMT than group II(Right: 0.86 vs. 0.70mm, p<0.001, Left: 0.90 vs. 0.73mm, p<0.001), lower common carotid artery end diastolic flow velocity(Right: 13.37 vs. 15.73m/s, p=0.002, Left: 14.46 vs.17.24m/s, p=0.004), and higher E/E'level(11.57 vs. 9.36, p=0.001). Old age, dyslipidemia, and diastolic dysfunction were independently associated with carotid plaques. CONCLUSION: Our results indicated that old age, male gender, diabetes, hypertension, and dyslipidemia are more com- mon in patients with carotid plaques than in those without. Old age, male gender, dyslipidemia, and diastolic dysfunc- tion are independent risk factors of carotid plaques in elderly patients with ischemic stroke. We further concluded that though left ventricle systolic function is not associated with carotid plaques in elderly patients with ischemic stroke, left ventricle diastolic dysfunction is.
