3.Notes from studying 86 patients with unstable angina treated at Cardiovascular Department of Viet Tiep Hai Phong Hospital from January 2004 to May 2005
Journal of Vietnamese Medicine 2005;0(11):39-45
A retrospective study was performed on 86 patients with unstable angina treated at Cardiovascular Department of Viet Tiep – Hai Phong Hospital from January 2004 to May 2005. Results: this disease occured mainly in age group of 51-80; there was no difference in prevalence between 2 genders. The hospitalized patients more likely live in urban than in rural (77.91% vs 22.09%). Most of patients had at least one risk factor; several patients had 2 or 3 risk factors. Most common risk factors are hypertension (53.49%), diabetes (15.21%), and dyslipidemia (46.5%). Angina appeared in rest time in 77.9%, and angina post-myocardial infarction angina accounted for 26.,74%. ECG was performed 2.62 times/patient. Heparin and aspirin are two most common used anti-coagulators (used in 70.09% and 84.88% of patients, respectively). Two drugs were used to treat myocardial ischemia are nitrat derivatives (87.21%) and beta-adrenergic blockers (40.7%). The hospitalized mortality rate was 4.65% due to ventricular fibrillation

5.The association of carotid atherosclerosis and coronary lesion in angina patients
Journal of Practical Medicine 2005;510(4):54-57
Study on 60 angina patients that suspected due to coronary artery diseases. Results: prevalence of hypertension was 76.7%, high blood cholesterol seen in 65%, and carotid artery diseases occurred in 73.3%. The rate of coronary artery disease is relative high (40%). Frequency of carotid artery diseases was almost 96% in coronary atherosclerosis group in comparison with 58% in group of patients without coronary artery stenosis or with less 50% of stenosis. Doppler ultrasound is confident, safe, and cheap method that can be performed bedside.

6.A Case of Left Ventricular Diverticulum.
Korean Circulation Journal 1985;15(3):503-506
Left ventricular diverticulum is rare cardiac malformation;fewer than 30 cases have been reported in the world. We present a case of left ventricular diverticulum with chest pain suggested unstable angina. Myocardial rupture of this case was occured during cardiac catherization. patient was recovered and discharged. Relevant literature was also reviewed.

Balloon angioplasty of stenosis involving a bifurcation of coronary arteries carries a significant risk of iatrogenic permanent occlusion of one of the adjacent branches. In order to prevent this complication, kissing balloon technique, inhitially, used for aortoplasty in Leriche synrome, was introduced into coronary angioplasty. Alternatively Oesterle described the single-guide, two-wire technique which is less traumatic with nearly equal outcomes. Among 200 coronary angioplasty cases done in our laboratory, 3 cases of unstable angina pectoris with stenosis involving major bifurcation sites were encountered. In 2 cases with stenosis involving left anterior descending artery and diagonal branch, kissing balloon technique was performed. Single-guide, two-wire technique was performed in remaining 1 case with stenosis of posterior descending and posterior lateral branchs. The outcome were successful without major complications.

The plasma levels of inflammatory cytokine interleukin-6 (IL-6) and anti-inflammatory cytokine interleukin-10 (IL-10) in the patients with unstable angina or stable angina were determined and compared. In 30 patients with unstable angina and 22 patients with stable angina, plasma levels of IL-10 and IL-6 were detected by ELISA and plasma lipid parameters by lipid research clinical methods respectively. The results showed plasma levels of IL-10 were significantly lower in unstable angina group than in stable angina group (P = 0.005), while those of IL-6 were significantly increased in unstable angina group as compared with those in stable angina group (P = 0.039). There was a significantly negative correlation between IL-10 and IL-6 in patients with unstable angina (r = -0.41, P = 0.003). In the unstable angina group, IL-6 levels were obviously positively correlated with TC (r = 0.314, P = 0.023), but not with TG and HDL. There were no significant correlations between IL-10 and plasma lipid parameters. It was suggested that the decreased IL-10 and increased IL-6 might be associated with the atheromatous plaque stability and progression of coronary heart diseases. IL-10 may play an important role in preventing coronary vascular lesions.

BACKGROUND: The diagnostic significance of ECG ergonovine test and the incidence of vasospastic angina in patients with chest pain are still uncertain. METHODS: From May 1998 to June 1999, 133 consecutive patients with chest pain were admitted for diagnostic coronary angiography. ECG ergonovine provocation tests were performed in 64 patients who have a clinical history suggesting vasospatic angina, including 27 of 28 patients with vasospastic angina documented electrocardiographically, or who's coronary angiographic findings could not be explained by their clinical history. Ergonovine was administered intravenously in incremental dose of 0.05, 0.1, 0.2, 0.3, 0.4 mg up to total cumulative dosage of 1.0mg during coronary angiography(41 cases), in the exercise laboratory(21 cases) or both(2 cases). RESULTS: Of 133 patients with chest pain, vasospastic angina was documented in 32(24%), unstable angina in 52(34%), stable angina in 10(8%), and others in 39(29%). Angiography demonstrated coronary spasm in 4 additional patients as well as 22 patients with vasospastic angina documented electrocardiographically, but ergonovine tests in the exercise laboratory showed positive response in 5 of 6 patients with vasospastic angina documented. Among the 25 patients with coronary spasm proved angiographically during ergonovine test, ECG findings at the time of coronary spasm were ST segment elevation in 21(84%), depression in 1(4%) and no change in 3(12%) patients, who had branch vessel spasm, 3 vessel spasm or incomplete spasm on coronary angiogram. Of the 31 patients with vasospastic angina who underwent ergonovine tests, positive response occurred in 24(77%) after a cumulative dose of < or = 0.4mg and in additional 3(10%) after the higher dose of >0.4mg. However the other 4(13%) had no ECG changes even after the higher dose(>0.4mg) of ergonovine. CONCLUSION: This results suggest that vasospastic angina appear to be a common cause of chest pain, and ECG ergonovine test with high dose can improve diagnostic sensitivity but cannot detect some patients with vasospastic angina.
