Abstract
Background and Aims To assess the 10-year cardiovascular disease (CVD) risk among Thai physicians. The risk compared to the general population and their relationship with the current coronary artery disease (CAD) were also examined. Methods This retrospective study collected data of Thai physicians who underwent cardiovascular assessments between February 14, 2022, and October 31, 2022. The CVD risk was calculated using the Thai CVD risk (TCVR) score, which incorporated variables of age, gender, smoking, diabetes mellitus, blood pressure, and total cholesterol. Additional collected data included family history of CAD, weekly work hours, fiber diet, exercise, body mass index, coronary artery calcium (CAC) score, and presence of CAD. The association between the risk levels with presence of CAD and clinical features including CAC score were analyzed. Results Of 1225 physicians, the risk for CVD development was categorized as low in 80.0%, moderate in 11.2%, high in 4.9%, and very high in 3.9%. Among these, 33.6% were found to have higher relative risk compared to the general population of the same age and gender. The overall prevalence of CAD was 11.2%. This prevalence was escalated by risk or relative risk groups: 4.9% in low-, 33.8% in moderate-, 35.1% in high-, and 46.8% in very high-risk groups or 7.2% in lower risk, 8.0% the same risk, and 18.4% higher relative risk groups. Conclusions Approximately, 20% of Thai physicians in the study exhibited a moderate to very high 10-year risk of CVD. Furthermore, 33.6% of the physicians had higher risk than individuals of the same age and gender in the general population. The prevalence of CAD increased with higher CVD risk and higher relative risk.

Abstract
BACKGROUND To evaluate the prevalence of cardiovascular disorders (CVDs), specifically coronary artery disease (CAD), among Thai physicians, and the cardiac testing being used. The associated or risk factors of CAD were also studied. METHODS Data of Thai physicians who participated in the hospital's corporate social responsibility "Save Doctors' Heart" project conducted between February 14, 2022, and October 31, 2022, were collected: personal illness, family history of CAD, workplace, work hours, dietary habits, exercise, stress, body mass index, laboratory and cardiac testing. RESULTS Of 1231 physicians, the median age was 48.0 ± 10.34 years, with 55.2% were female; 83.1% reported working <55 h per week, 29.7% exercised ≥3 days a week, and 28.0% were overweight or obese. Hypertension, diabetes mellitus, and dyslipidemia were found in 46.3%, 30.5%, and 75.8%, respectively. Abnormal findings were observed in 29.7% of chest X-rays, 17.7% of electrocardiograms, 33.0% of echocardiograms, 10.6% of exercise stress tests, and 3.8% of stress echocardiograms. Moderate/extensive coronary artery calcium (CAC) scores were present in 12.7%. The prevalence of CVDs or CAD were 51.7% and 11.2%, respectively. Independent risk factors for CAD included older age, male gender, history and/or new findings of DM, and moderate to extensive CAC scores. CONCLUSION The prevalence of CVDs and CAD among Thai physicians is 51.7% and 11.2%, respectively. The independent risk for CAD was older age, male, having DM, and moderate to extensive CAC scores. The physicians who are at risk should be cautious, modify their lifestyle, and have appropriate screening/diagnostic testing for cardiac abnormality.

Abstract
BACKGROUND The Can Rapid Risk Stratification of Unstable Angina Patients Suppress Adverse Outcomes with Early Implementation of the ACC/AHA Guidelines (CRUSADE) score has been recommended to predict in-hospital bleeding risk in non-ST segment elevation myocardial infarction (NSTEMI) patients. The evaluation of the CRUSADE risk score in Asian patients undergoing contemporary percutaneous coronary intervention (PCI) for NSTEMI is necessary. AIMS We aimed to validate and update the CRUSADE score to predict in-hospital major bleeding in NSTEMI patients treated with PCI. METHOD The Thai PCI registry is a large, prospective, multicenter PCI registry in Thailand enrolling patients between May 2018 and August 2019. The CRUSADE score was calculated based on 8 predictors including sex, diabetes, prior vascular disease (PVD), congestive heart failure (CHF), creatinine clearance (CrCl), hematocrit, systolic blood pressure, and heart rate (HR). The score was fitted to in-hospital major bleeding using the logistic regression. The original score was revised and updated for simplification. RESULTS Of 19,701 patients in the Thai PCI registry, 5976 patients presented with NSTEMI. The CRUSADE score was calculated in 5882 patients who had all variables of the score available. Thirty-five percent were female, with a median age of 65.1 years. The proportion of diabetes, PVD, and CHF was 46%, 7.9%, and 11.2%, respectively. The original and revised models of the CRUSADE risk score had C-statistics of 0.817 (95% CI: 0.762-0.871) and 0.839 (95% CI: 0.789-0.889) respectively. The simplified CRUSADE score which contained only four variables (hematocrit, CrCl, HR, and CHF), had C-statistics of 0.837 (0.787-0.886). The calibration of the recalibrated, revised, and simplified model was optimal. CONCLUSIONS The full and simplified CRUSADE scores performed well in NSTEMI treated with PCI in Thai population.

Abstract
Background Physicians, due to their work and lifestyle patterns, can be at risk for metabolic syndrome (MetS). We aimed to evaluate the prevalence of MetS among physicians and its association with coronary artery disease (CAD). Materials and methods This retrospective cross-sectional study collected data on Thai physicians who had medical examination including cardiovascular testing from 14 February to 31 October 2022, in our hospital. Inclusion criteria were those who had complete data for MetS diagnosis per Adult Treatment Panel III criteria and CAD diagnosis information. Outcome measures were prevalence of MetS and CAD prevalence in affected vs non-affected physicians. Results Of 1194 physicians, the median age was 48.0±10.29 years. The authors found 4.5% were obese, 30.6% having high blood pressure, 26.6% high fasting blood sugar (FBS), 12.7% high triglycerides, and 13.7% low high-density lipoprotein (HDL). The prevalence of MetS was 8.9%. Increasing age, systolic blood pressure, body mass index, FBS, triglyceride, and decreasing HDL were identified as independent risk factors of MetS. The prevalence of CAD was 11.4%: 47.2% vs. 7.9% among the physicians with and without MetS respectively (odds ratio 10.41: 95% CI, 6.70-16.16%, P<0.001). Conclusion The prevalence of MetS among Thai physicians in this study was 8.9%. Those physicians with MetS were associated with a 10-fold higher risk of CAD. Physicians who were at risk of developing MetS should consider modifying their health habits and being vigilant about the potential consequences of CAD. Further prospective cohort studies are warranted to validate these results.

Abstract
Introduction Cardiovascular diseases (CVDs) are major global health problem and are the third leading cause of death in the world. Most studies found the neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) were correlated with myocardial infarction and heart failure. Previous studies reported a higher risk of CVD among physicians but no study concerns NLR and the PLR to predict coronary artery disease (CAD) among the physicians. Purpose This study aimed to evaluate the role of blood features in the CBC, with a particular focus on NLR and PLR levels, in predicting the presence of CAD. Patients and Methods Data of Thai physicians who participated in the "Save Doctors' Heart" project which was conducted between February 14 and October 31, 2022, were collected from personal information, work and health habits, physical examination, white blood cell (WBC), laboratory, cardiac testing, and presence of CAD. Prior to studying their association with CAD, optimal values of age and each blood parameter, NLR, and PLR were determined. Results Of 1161 physicians mean age was 47.7 ± 10.16 years. By cardiac tests, CAD was identified in 11.3%. Significantly higher levels of WBC, neutrophils, NLR, and lower platelets were found in physicians with CAD. Except for lymphocytes and platelets which exhibited a reverse association with CAD, other factors were found as significant risk factors for CAD by univariate analysis. By multivariate analysis, the independent risk factors for CAD in order of their adjusted odds ratio (aOR) were age ≥50 years (aOR 9.34), NLR ≥ 1.87 (aOR 2.75), CAC score > 1 (aOR 2.39), and PLR ≥ 161.66 (aOR 2.32). Conclusion NLR and PLR, older age and CAC score were found as independent factors predicting CAD. The findings of this study could potentially provide valuable insights into the relationship between blood parameters and CAD risk among physicians.

Abstract
Background Timely reperfusion therapy is recommended for patients with ST-segment elevation myocardial infarction (STEMI), and system delay <90 minutes and door-to-device (D2D) time <60 minutes are recommended by the 2017 ESC Guidelines for the management of STEMI patients and have been proposed as a performance measure for triaging patients for primary percutaneous coronary intervention (PCI). However, previous research produced contradictory results regarding the association between D2D time and mortality. Therefore, this study aimed to examine the associations between D2D time and mortality in Thailand. Methods This cohort study included STEMI patients treated with primary PCI in 39 PCI centres in Thailand from February 27, 2018, to August 1, 2019. Patients were eligible if they met the following criteria: primary STEMI diagnosis, symptom onset within 12 hours, and ST-segment elevation of at least 0.1 mV in 2 or more contiguous leads (at least 0.2 mV in V1-V3) or a new left bundle branch block. Results Within 12 hours of symptom onset, 3,874 patients underwent primary PCI. The median D2D time was 54 minutes [interquartile range (IQR) 29-90], and there was a significant difference between patients transferred from other hospitals (44 minutes, IQR 25-77, n=2,871) and patients presented directly to PCI centres (81 minutes, IQR 56-129, n=1,003) (P<0.001). Overall, in-hospital mortality was 7.8%. In a multivariable analysis, adjusting for other predictors of mortality and stratifying according to intervals of D2D time, cumulative in-hospital mortality was significantly higher in patients with a D2D time greater than 90 minutes [hazard ratio (HR) 1.5, 95% confidence interval (CI): 1.0-2.1, P=0.046] but not associated with D2D time shorter than 60 minutes (HR 1.2, 95% CI: 0.8-1.8, P=0.319). Conclusions A D2D time greater than 90 minutes was related to in-hospital mortality in patients with STEMI treated with primary PCI, but a D2D time less than 60 minutes was not consistently associated with D2D time-improved survival in real-world, contemporary practice in Thailand.

Abstract
Background Despite numerous studies supporting the outperformance of ultrathin-strut bioresorbable polymer sirolimus-eluting stent (Orsiro SES, Biotronik AG), the generalizability of the study results remains unclear in the Asian population. We sought to evaluate the clinical outcomes of the Orsiro SES in unselected Thai population. Methods The Thailand Orsiro registry was a prospective, open-label clinical study evaluating all patients with obstructive coronary artery disease implanted with Orsiro SES. The primary endpoint was target lesion failure (TLF) at 12 months. TLF is defined as a composite of cardiac death, target vessel myocardial infarction (TVMI), emergent coronary artery bypass graft (CABG), and clinically driven target lesion revascularization (CD-TLR). Patients with diabetes, small vessels (≤ 2.75 mm), chronic total occlusions (CTOs), and acute myocardial infarction (AMI) were pre-specified subgroups for statistical analysis. Result A total of 150 patients with 235 lesions were included in the analysis. Half of the patients (53.3%) presented with AMI, and 24% had diabetes. Among 235 lesions, 93(39.4%) were small vessels, and 24(10.2%) were chronic total occlusions. The primary endpoint, TLF at 12 months, occurred in eight patients (5.3%), predominately caused by cardiac death. By contrast, the incidences of TVMI and CD-TLR were null. The outcomes in pre-specified subgroup were not different from the overall population (all p > 0.05). One definite late stent thrombosis(0.7%) was incidentally observed during primary percutaneous coronary intervention to the non-target vessel. Conclusion The safety and efficacy of the ultrathin strut sirolimus-eluting stent in unselected cases are confirmed in the Thailand Orsiro registry. Despite the high proportion of pre-specified high-risk subgroups, the excellent stent performance was consistent with the overall population. Trial Registration TCTR20190325001.

Abstract
OBJECTIVE To compare the efficacy and safety of original (Plavix) and generic (Apolets) clopidogrel 600 mg loading in patients planning to undergo coronary angiography. MATERIAL AND METHOD This is an experimental design, parallel, randomized-controlled study. Coronary artery disease patients planned for cardiac catheterization were recruited Patients were randomized to receive either original or generic clopidogrel 600 mg loading dose. Platelet aggregation induced by 5 micromol/L and 20 micromol/L adenosine diphosphate (ADP) was measured by light transmission aggregometry (LTA) at baseline and 6 hours after clopidogrel 600 mg administration. RESULTS Forty-nine patients were enrolled, 24 patients received original clopidogrel, and 25 patients received generic clopidogrel. After six hours of loading, there was significantly reduction in platelet aggregation induced by adenosine 5 micromol/L from 41.08 +/- 3.04% to 19.50 +/- 1.68% (p < 0.001) in original group compared to 36.76 +/- 2.66% to 21.32 +/- 2.60% (p < 0.001) in generic group. When induced by 20 micromol/L, the platelet aggregation was reduced from 58.50 +/- 2.09% to 32.25 +/- 2.30% (p < 0.001) in original group and from 61.12 +/- 2.54% to 30.04 +/- 3.14% (p < 0.001) in generic group. There was no significant difference between original and generic clopidogrel in reducing platelet aggregation induced by both adenosine 5 and 20 micromol/L. Groin hematoma was found in one case (4.2%) in the original clopidogrel group. CONCLUSION Generic clopidogrel (Apolets) 600 mg loading dose is as effective as original clopidogrel (Plavix) in term of platelet aggregation inhibition.

Abstract
BACKGROUND Primary percutaneous coronary intervention (PCI) appears to be the preferred reperf usion methodfor patients with ST-segment elevation myocardial infarction (STEMI). This method was introduced in our hospital before the year 2000. In Thailand, data showing long experience results in patients with STEMI who underwent primary percutaneous coronary intervention remain limited. OBJECTIVE To demonstrate 11-yr experience of primary percutaneous coronary intervention at King Chulalongkorn Memorial Hospital. MATERIAL AND METHOD This retrospective descriptive single-center study analyses clinical characteristics, angiographic features and in-hospital outcomes of 772 patients with STEMI who underwent primary percutaneous coronary intervention between 2000 and 2010. RESULTS Seven hundred seventy two consecutive patients with STEMI were enrolled in the study. Three-fourth of the patients were male. Mean age was 60.13 years (range 28 to 96 years) and 12.6% were older than 75 years old. Forty-eight percent of patients were referred from hospital without cardiac catheterization facilities. Of these patients 94.4% underwent primary PCI and rescue PCI was done in 5.6% of patients. There were 27% ofpatients with left ventricular ejection fraction less than 40%, 21% of patients with Killip's class IV and 12% suffered cardiac arrest prior to angiography. Median door-to-balloon time in referred and non-referred patients was 28 and 104.5 minutes, respectively. Ninety-two percent of referred patients and 36% of non-referred patients, door to balloon time were within 90 minutes. About half ofthe patients had multi-vessels disease at that time of diagnosis. The overall angiographic success rate was 96%. Platelet glycoprotein llb/lla inhibitors were used in two-third ofpatients and stent placement in 82%. Post procedural thrombolysis in myocardial infarction (TII) 3 flow was documented in 87%. Intra-aortic balloon pump was used in 15% and thrombus aspiration device in 47%. During hospital stay, in-hospital mortality was 8.5% and 80% of those cases died from cardiac cause. One-third of patients died if they had Killip's class IV at presentation compared with 1.6% in patients with Killip's class I-III. In-hospital major adverse cardiovascular event was 10.4%. CONCLUSION During 11 years of primary PCI experience in King Chulalongkorn Memorial Hospital, the angiographic success rate was high with acceptable in-hospital mortality and major adverse cardiac event. This strategy of treatment should be the treatment of choice for patients with STEMI in experienced PCI capable center with 24 hours/7 days availability.

Abstract
BACKGROUND Left Main Coronary Artery (LMCA) disease is now uniformly treated with coronary artery by pass grafting (CABG). However some patients with LMCA disease did not receive CABG because of high operative risks as well as those who refused CABG Recent studies demonstrated the feasibility of stenting for LM stenosis, although data remain limited. OBJECTIVE To evaluate in-hospital and mid-term outcomes of using bare metal stent (BMS) and drug eluting stent (DES) in protected and unprotected left main coronary artery disease at King Chulalongkorn Memorial Hospital. MATERIAL AND METHOD Retrospective, single-center study. The authors reviewed the outcomes of patients who underwent percutaneous coronary intervention on left main coronary artery lesions in our hospital from July 2000 to August 2007. In-hospital data and clinical follow-up outcomes were analyzed and determined as in-hospital and mid-term mortality, major adverse cardiac event (MACE). RESULTS In eight years the authors reviewed 64 consecutive protected and unprotected LMCA patients who underwent PCI with stent placement. Altogether left main coronary artery stents were successfully deployed in all patients. DES usage was 64%. Bifurcation technique for distal left main coronary artery was executed in 32 patients (50%), included single stent in 62 (97%), two stents in 2(3%). Final kissing ballon inflation was done in 14 (21.9%). In-hospital mortality was 4.7% (three patients), two patients died from cardiac origin. The total in-hospital major adverse cardiac event (MACE) was 4.7%. Clinical follow-up of 6 months was completed in 100% of patients. Fifty percent of patients had angiographic follow-up and in-stent restenosis rate was 9.7%. No further death was noted and MACE at 6 months was 9.4%. Moreover, overall mean and median follow-up period were 31 +/- 25 months (range, 6-93 months) and 26 months respectively. CONCLUSION Stent Implantation was technically feasible and safely applied for the treatment ofprotected and unprotected left main coronary artery lesions in patients, with acceptable in-hospital and mid-term outcomes. More randomized and controlled clinical trials are needed to confirm the long-term effects of stents for LMCA disease.

Abstract
BACKGROUND Early primary coronary interventions (PCI) in acute ST elevation myocardial infarction (STEMI) is associated with improved outcome and mortality rate but delayed reperfusion especially after 6 hours is still doubtful in terms of clinical benefits because most myocardial muscle are infarcted after 6 hours of onset of chest pain. OBJECTIVE The aim of the present study was to compare the mortality rate of patients treated with PCI within 6 hours of symptom onset to those treated between 6 to 24 hours after the onset of STEMI. MATERIAL AND METHOD The present study included consecutive patients from the data of the Fast Track Registry of King Chulalongkorn Hospital from June 1, 1999 to October 31, 2003 to compare the thirty-day mortality of patients treated with early or delayed PCI (0-6 hours vs. 6-24 hours after symptom of chest pain) for STEMI. RESULTS Two hundred and sixteen patients who underwent PCI were enrolled. Male gender (82% vs. 64.9%, p = 0.03) and history of smoking (72.1% vs. 50%, p = 0.04) were predominant in the early treatment group (ETG) vs. the delayed treatment group (DTG). Mean age (60.5% vs. 61.03%, p = 0.11), diabetes (31.4% vs. 29.7%, p = 0.82), hypertension (64.0% vs. 54.1%, p = 0.20), dyslipidemia (58.1% vs. 60.8%, p = 0.73), and ejection fraction < 40% (22.8% vs. 32.0%, p = 0.625) were similar in both groups. There were no differences in angiographic finding and hospital management. Door to balloon and total delay time were 124.13 +/- 143.27 min and 407.94 +/- 268.183 min, respectively. The thirty-day mortality (9.01% vs. 12.76%, p = 0.379) and I year mortality (12.4% vs. 16 9%, p = 0.532) were not significantly determined by Log rank test in both groups. As for cardiogenic shock, ETG tended to have a lower thirty-day mortality than DTG but no statistically significant difference (12.5% vs. 50.0%, p = 0.0809). CONCLUSION The delayed PCI up to 24 hours in STEMI does not increase short-term mortality at thirty days; therefore, it may still have benefit in STEMI patients. However it tended to have higher short-term mortality than early PCI especially in cardiogenic shock but showed no statistical significance.

Abstract
BACKGROUND Percutaneous coronary intervention (PCI) is now a favorable treatment for acute ST elevation myocardial infarction (STEMI). However, in non-official hours (non-OH), this modality of treatment has a questionable outcome because of the treatment delay. OBJECTIVE To compare the outcomes of PCI during official hours (OH) with non-OH in acute STEMI patients. MATERIAL AND METHOD A prospective consecutive registry of PCI in acute ST-elevation MI patients at King Chulalongkorn Memorial Hospital from May 1999 to December 2003 were analyzed. Kaplan Meier survival analysis was used to determine the in-hospital mortality. Multivariate analysis was used to determine the prognostic factors for in-hospital mortality. RESULTS Two hundred and fifty six consecutive patients (OH-107, non-OH-149) who underwent PCI for acute STEMI were enrolled. Their mean age (61.9 +/- 12.2 vs 60.6 +/- 12.8 y, p = ns), male gender (73.8% vs 73.2%, p = ns), history of diabetes (30.2% vs 33.8%, p = ns), severity of the patients (percent of patients in Killip IV--22.4 vs 21.5, p = ns), ejection fraction (48.7 +/- 15.1 vs 45.9 +/- 14.7, p = ns), cardiopulmonary resuscitation prior PCI (15.0% vs 14.2%, p = ns), anterior MI (55.1% vs 51.0%, p = ns) were similar in both groups. Hypertension was slightly less common (39.6% vs 52.7%, p = 0.04) but smoking was more common (62.6% vs 49.0%, p = 0.03) in OH group. Door to balloon time and decision to balloon time were significantly shorter in the OH group than the non-OH group (67.9 +/- 47 vs 119.6 +/- 83 min, p < 0.001 and 60.8 +/- 35 vs 98.3 min, p < 0.001). However, the total delayed time was not statistically significantly different (402 +/- 316 vs 424 +/- 215, p = 0.55). Angiographic success rate was achieved in 98.1% for the OH group and 94.7% in the non-OH group (p = ns). In-hospital mortality rate was 10.3% and 10.7% respectively. CONCLUSION The door to balloon time for PCI in acute STEMI patients in the non-OH group was longer than the OH group; however, the total delayed time was not different. The in-hospital mortality rate was similar.

Abstract
Several randomized trials have demonstrated that stent implantation after successful recanalization of long-term total occlusions decreases restenosis and reocclusion rates. The sirolimus-eluting stent (SES) has recently proved its efficacy to decrease restenosis in selected patients. However, the efficacy of SES implantation in patients who have chronic total occlusions is currently unknown. Therefore, we investigated procedural and 6- and 12-month angiographic outcomes (analyzed by quantitative coronary angiography) and left ventricular function in 60 patients who received SESs and 120 patients who received bare metal stents (BMSs). Minimum luminal diameter did not differ immediately after recanalization (SES group 3.04 +/- 0.50 mm vs BMS group 3.12 +/- 0.48 mm). After 6 months, the SES group still had significantly larger luminal diameters (3.04 +/- 0.44 mm vs 1.94 +/- 0.98 mm) and significantly lower restenosis and reocclusion rates (2% and 0%, respectively) than did the BMS group (32% and 6%, respectively). Late loss was significantly smaller in the SES group than in the BMS group. At follow-up, the SES group had fewer cardiac events, including target lesion revascularization (p <0.001), than did the BMS group. In conclusion, SES implantation after recanalization of chronic total occlusion provides a better clinical outcome with less restenosis and target lesion revascularization after 6 months than does BMSs.

Abstract
BACKGROUND Many reports have shown that female gender carries a worse prognosis when developing acute myocardial infarction (MI), whether or not reperfusion therapy is used. The primary percutaneous coronary intervention (1-PCI) is currently a preferable treatment for acute ST-elevation MI. However, the data concerning the difference between the outcomes in the treatment of the disease in men and women in Thailand is still insufficient. MATERIAL AND METHOD A prospective registry of acute ST-elevation MI patients who underwent 1-PCI at King Chulalongkorn Memorial Hospital from June 1999 to December 2002 were analyzed. Kaplan Meier survival analysis is used to determine the in-hospital mortality. RESULTS The consecutive 184 (F-52, M-131) patients who underwent 1-PCI were recruited. Female subjects were older (66.6 +/- 12 y versus 59.0 +/- 11.6 y, p < 0.01); they also had higher percentage of diabetes (45.1 versus 27.1, p < 0.01), but a fewer number of smoker (17.7 versus 66.2, p < 0.001). The percentage of patients who had cardiogenic shock tended to be higher in women (34.6 versus 19.9, p = 0.08); however, the number of anterior wall MI and ejection fraction were not different. The mean door to balloon time (109 +/- 95 versus 99 +/- 68 minutes) and pain to balloon time (454 +/- 271 versus 372 +/- 298 minutes) were not different in both groups. The angiographic success with TIMI 3 flow was achieved in 92.3% for females and 86.9% for the males. The in-hospital mortality was significantly higher in females (23.1 versus 6.1, p = 0.002). Univariate analyses demonstrated that the feminine gender, cardiogenic shock, smoking, ejection fraction less than 40, cardiac arrest prior PCI and angiographic were the predictors for in-hospital mortality. When using multivariate analyses by Cox proportional model, only cardiogenic shock, history of hypertension and angiographic success were the significant predictors. Women had 2.15 times of in-hospital mortality higher than males; however, the confidence interval cross-over 1 (0.74-6.42) and p value was 0.16. CONCLUSION Females tend to have a poor prognosis when they develop acute ST-elevation MI which requires treatment with 1-PCI.

Abstract
An imbalance between oxidative damage and antioxidative protection in association with the pathophysiology of atherosclerosis has been suggested. The aim of our study was to investigate the relationship between plasma lipids, the antioxidant system and oxidative damage in Thai patients with stable coronary artery disease (CAD). Sixty-one patients (40 males, 21 females), who were angiographically defined as having CAD and were clinically stable, participated in this study. Thirty-two healthy subjects (20 males, 12 females) served as normal controls. The investigation included the measurements of plasma lipid profiles and plasma total antioxidative status (TAS) such as plasma vitamin E erythrocyte glutathione (GSH) and glutathione peroxidase (GPx), as well as malondialdehyde (MDA) and total plasma total protein thiols (P-SH). In patients with CAD, erythrocyte GSH and GPx were significantly lower than those found in controls. However plasma TAS and vitamin E were not significantly different between groups. Patients with CAD also had higher MDA and lower P-SH levels than the controls, which represents the oxidative damage products of lipid and proteins. Multiple regression analysis revealed negative correlations between GSH and cholesterol, GSH and low density lipoprotein (LDL), vitamin E and MDA, as well as P-SH and MDA. This study demonstrated the status of oxidative stress in patients with stable CAD. Since oxidative stress is the imbalance between the total oxidants and antioxidants in the body, any single oxidant/antioxidant parameter may not reflect the overall oxidative stress system. Thus, in patients with CAD, diets with various types of antioxidants may be more beneficial in increasing antioxidant activity than any particular antioxidant supplementation.

Abstract
UNLABELLED PTCA is one of the treatments for coronary heart disease. But in Thailand, there is no available data on the long-term outcomes of patients who have undergone this procedure. To determine initial and long-term outcomes of patients who underwent percutaneous transluminal coronary angioplasty (PTCA), patients who underwent PTCA from January 1996 to December 1997 were enrolled. The initial results were received from the PTCA registry. The follow-up data were collected from medical records, phone calls and mail. Three hundred and forty patients (male 68.8%) were enrolled. Mean age was 61.8 +/- 10.1 years. Dyslipidemia was the most common risk factor (50.3%), followed by hypertension (44.4%), smoking (40%), and diabetes (33.8%). Indications for PTCA were chronic stable angina (47.9%), unstable angina (22.1%), acute myocardial infarction (4.3%) and post myocardial infarction angina (25.8%). Diseased vessels were left anterior descending (44.8%), right coronary artery (28.0%), left circumflex artery (25.5%), left main artery (0.9%) and saphenous vein grafts (0.8%). Initial case success rate was 93.5 per cent. Stent was implanted in 41.8 per cent of cases. In-hospital mortality rate was 1.2 per cent. Two patients (0.6%) developed Q-wave myocardial infarction (MI). Four patients (1.2%) required emergency bypass surgery (CABG). Major adverse cardiac events occurred in 6 patients (1.8%). Two hundred ninety one patients (85%) had complete follow-up data, mean follow-up time was 990 +/- 326 days. Twenty-one patients died (6.4%) but only 12 (3.5%) were cardiac in origin. Other cardiovascular events were non-fatal MI (1.2%), unstable angina (10.7%), congestive heart failure (4.6%), and chronic stable angina (41.1%). Target lesion revascularization by PTCA was done in 55 patients (16.9%) and CABG was performed in 22 patients (6.7%) CONCLUSION PTCA can be performed with a high success rate and low in-hospital complications. Long-term outcomes are acceptable and comparable with Western data.

Abstract
BACKGROUND Lesions in small-diameter vessels (<3 mm) define a group with distinct clinical and morphological characteristics. There is an inverse relationship between vessel size and angiographic restenosis rate. This study assessed whether stents reduce angiographic restenosis in small coronary arteries compared with standard balloon angioplasty. METHODS AND RESULTS We randomly assigned 351 symptomatic patients needing dilatation of 1 native coronary vessel between 2.3 and 2.9 mm in size to angioplasty alone (n=182) or stent implantation (n=169). The primary end point was angiographic restenosis at 6 months. Secondary end points included death, myocardial infarction, bypass surgery, and target vessel revascularization in hospital and at 6 months. There were no significant differences between groups in terms of major in-hospital complications. There was a trend toward fewer in-hospital events in the stent group (3% versus 7.1% in angioplasty group, P=0.076). Crossovers to stent occurred in 37 patients (20.3%). Repeat angiography at 6-month follow-up was performed in 85.3% of patients. Angiographic restenosis occurred in 28% of the stent group and 32.9% of the angioplasty group (P=0.36). Target vessel revascularization was required in 17.8% versus 20.3% of patients (P=0.54), respectively. CONCLUSIONS Stenting and standard coronary angioplasty are associated with equal restenosis rate in small coronary arteries. With a lower in-hospital complication rate, stenting may be a superior strategy in small vessels.

Abstract
BACKGROUND Acute myocardial infarction (AMI) with cardiogenic shock carries a high mortality rate. Early revascularization shows better results than conservative medical treatment. OBJECTIVE To determine short and long term results of patients with cardiogenic shock from AMI who underwent percutaneous coronary intervention (PCI). METHODS Patients were identified from the PCI registry from 1993 to 1999. Follow-up data were collected from medical records and/or phone calls. RESULTS From 1993 to 1999, there were 1211 PCI procedures performed at King Chulalongkorn Memorial Hospital. Seventeen of these cases (M9, F8) had cardiogenic shock. Mean age was 59 +/- 14 yrs. Fourteen patients had AMI. The other 3 cases developed shock more than 24 hours after AMI. Primary PCI was done in 11 cases. Thirteen patients (76.5%) needed intra-aortic balloon pump support. Average peak CPK and CK-MB were 5393 and 580 u/l, respectively. Five patients (29.4%) died in hospital, 3 of whom died on the first day due to pump failure. Twelve patients were followed for a mean duration of 412 days (range 12 - 1,464). One patient died 6 months after PTCA because of in-stent restenosis of the left main coronary artery. CONCLUSION AMI with cardiogenic shock has a high mortality rate. However, in this group of patients who had early revascularization by PCI, mortality seemed to be lower than previously reported. If PCI is available, the procedure should be offered for this subset of AMI patients.

Abstract
To evaluate the effects of angiotensin converting enzyme inhibitor (ACE-I) on diabetic cardiovascular complications, a streptozotozin (STZ, i.p., 70 mg/kg BW) induced diabetes rat model was used. The animals were separated into four major groups including: control (NSS), STZ-treated rats, STZ-treated rats received daily oral feeding of cilazapril starting one day after STZ injection (STZ-C1), and STZ-treated rats received daily oral feeding of cilazapril eight weeks after the STZ injection (STZ-C8). Within the groups of STZ-C1 and STZ-C8, the animals were also divided into three subgroups of six rats that received different doses of cilazapril treatment, 0.01 mg/Kg BW, 1 mg/Kg BW, and 10 mg/Kg BW. By using the modified isolated heart model, the parameters of mean arterial pressure (MAP), heart rate (HR), left ventricular isotonic contraction (LVIC), aortic flow rate (AFR), coronary flow rate (CFR), and ratio of heart weight per body weight (R) were assessed for each groups 8 and 20 weeks after the STZ injections. Moreover, the changes of wall thickness of the left ventricular wall (LV), right ventricular wall (RV), and interventricular septal wall (IVS) were monitored from the scanning electron micrographs of each heart. The results indicated that in both STZ-C1 and STZ-C8, the diabetic hypertension could be prevented or treated by anti-hypertensive doses of cilazaprils. Besides, the values of AFR, CFR, and LVIC were significantly increased when comparing between the STZ and STZ-C1 or STZ-C8. The results of morphological examinations indicated that: (1) left ventricular walls of the three hearts of STZ-rats had increased significantly more than controls. (2) Right ventricular walls and interventricular septal walls were not significantly different among STZ-rats, cilazapril treated STZ-rats and age matched controls. Therefore, it is concluded that ACE-I could act either as a cardioprotective or therapeutic agent for diabetic hearts. Both major anti-hypertension and anti-trophic effects of ACE-I have already been elucidated.

Abstract
Diabetes is one of the controllable risk factors of coronary artery disease. Many reports have shown that diabetes is a poor prognostic indicator for coronary events and revascularization among patients who undergo PTCA or coronary artery bypass surgery. The present work, the first prospective study in Thailand, was conducted to compare the demographic data and initial outcomes of diabetic patients (DM) with those of non-diabetic ones (non-DM) who underwent percutaneous coronary angioplasty (PTCA). Data between January 1993 and December 1998 were prospectively collected after each procedure and before discharge. During the 6-year period, 812 patients (DM-280, non-DM-532) were enrolled. The DM group had significantly more female patients (45.4 vs 21.1%, p < 0.0001), older age (62.5 +/- 8.2 vs 60.5 +/- 10.8 y, p < 0.007), less smoking (21.8 vs 43.2%, p < 0.0001), more dyslipidemia (56.8 vs 41.9%, p < 0.0001) and a higher incidence of hypertension (51.8 vs 42.5%, p = 0.01). The left ventricular ejection fraction, indication for PTCA, size of attempted vessel, and number of diseased vessels were similar in both groups. The case success rate was 93.9 per cent in the DM group and 92.3 per cent in the non-DM group (P=NS). Two patients (0.7%) in the DM and three cases (0.6%) in the non-DM group died during hospitalization. Overall major adverse cardiac events were not different between both groups (1.4 vs 1.9%, P =NS). In conclusion, there were some demographic differences in DM compared with non-DM patients who undergo PTCA; but initial outcomes, major adverse cardiac events, and mortality rates were not significantly different.

Abstract
BACKGROUND Atrial fibrillation (AF) occurs frequently in severe rheumatic mitral stenosis (MS) and has been reported to be a predictor of poor outcome after percutaneous transvenous mitral commissurotomy (PTMC). Nevertheless, according to observations in our catheterization laboratory, patients with sinus rhythm (SR) seem to have a higher pulmonary artery pressure than AF. PURPOSE To determine 1) the hemodynamic differences between MS patients with AF and SR before and after PTMC and 2) the success rate and difference in outcome between both groups. METHOD A total of 145 patients who had undergone PTMC with the Inoue balloon technique in King Chulalongkorn Memorial Hospital between 1993 and 1997 were enrolled. The data were presented as mean +/- SD. Student t-test was used to compare the difference in hemodynamic and outcome between the AF and SR groups. RESULTS Fifty-six patients (38.6%) were in the AF group. The AF patients were older (42.0 +/- 11.3 vs 32.4 +/- 8.7 yr., p < 0.0001), had a larger left atrium (49.2 +/- 6.1 vs 45.3 +/- 4.9 mm, p < 0.001) and a higher valvular calcification score (1.8 +/- 0.6 vs 1.5 +/- 0.6, p = 0.02) than the SR group. There was no significant difference between baseline heart rate and overall MV score index. The hemodynamic data showed that the SR group had higher systolic (59.9 +/- 26.0 vs 47.4 +/- 16.8 mmHg, p < 0.05), diastolic (28.1 +/- 12.8 vs 22.7 +/- 9.2 mmHg, p < 0.05) and mean (40.1 +/- 17.1 vs 32.7 +/- 11.8 mmHg, p < 0.05) pulmonary artery (PA) pressure than the AF group. After successful PTMC, the SR group exhibited a more favorable change in all PA pressures and the transmitral valvular gradient (10.0 +/- 6.5 vs 6.7 +/- 6.5 mmHg, p < 0.01) than the AF group. Procedural success rates were 98 per cent in the AF and 96 per cent in the SR group (p = ns). Transthoracic colour-flow echocardiographic imaging detected atrial septal defects in 18.2 per cent and 7.5 per cent (p = 0.08) of the AF and SR groups, respectively. There was no systemic embolization, peri-procedural death or emergency surgery in both groups. CONCLUSION Patients with MS and AF were older, had a larger LA and lower pre-PTMC PA pressure than the patients who had MS and SR. In addition, patients with SR had a more favourable PA and LA pressure reduction than patients with AF.

Abstract
BACKGROUND The detection of myocardial ischemia after percutaneous transluminal coronary angioplasty (PTCA) is important because 30-50 per cent of the patients will develop restenosis within 6 months. Symptoms of chest pain and exercise stress test (EST) have shown to be less sensitive for detection of ischemia than exercise Technetium-99m Sestamibi (Tc-99m MIBI). The purpose of this study was to compare the sensitivity and specificity of chest pain, EST and Tc-99m MIBI with coronary angiography (CAG). METHOD Tc-99m MIBI with SPECT imaging was performed at months 1, 3 and 6 and CAG was repeated 6 months after successful PTCA. Earlier Tc-99m MIBI and CAG were performed in patients with recurrent angina pectoris or suspected restenosis. RESULTS Forty six patients (M 29, F 17) who had undergone successful angioplasty were prospectively enrolled. Their mean age was 61 +/- 19 yrs. Eighty eight lesions (LAD63%, LCX34%, RCA19%) were performed. Lesion characteristics were type A in 9 per cent, type in B 30 per cent and type C in 61 per cent. Fifty four per cent of PTCA were performed for single vessel disease and 46 per cent for multivessel disease. The mean duration of time between PTCA and follow-up CAG was 6.1 +/- 2.7 months. We detected restenosis from CAG in 58 per cent of the cases. The Tc-99m MIBI had higher sensitivity to detect restenosis than anginal pain (85.0% vs 39.4% p < 0.005) or EST (85.0% vs 63.6% p < 0.05) when compared with CAG. The overall accuracy of Tc-99m MIBI for the detection of restenosis was 80 per cent. CONCLUSION Tc-99m MIBI with SPECT imaging constitutes a better means than symptoms or exercise test to detect restenosis after successful coronary angioplasty.

Abstract
OBJECTIVES This study was conducted to compare the safety and initial outcomes applying reused balloon (RB) catheters with those of attained new balloon (NB) catheters when performing percutaneous transluminal coronary angioplasty. BACKGROUND Recently, PTCA procedures have been used increasingly for the treatment of patients with coronary heart disease. In the era of national economic constraint, reused balloon catheters will reduce the cost of expensive, imported coronary angioplasty devices. Hence, data concerning the safety and success rate of RB catheters compared with NB catheters are urgently required. METHODS Prospective comparative study between reused and new balloon catheters for coronary angioplasty. Data forms were completed after each procedure and before the patient was discharged after an 18-month period. RESULTS From July 1996 to December 1997, 221 cases (121-RB, 100-NB) were enrolled. Mean age, ejection fraction, diseased vessel and lesion characteristics were similar in both groups. The number of lesions was much higher performed in the RB than in the NB group (1.7 +/- 0.9 vs 1.4 +/- 0.8, p = 0.02). The RB group had more cases of acute myocardial infarction than the NB group (7.4% vs 1%, p = 0.003), however, the angiographic and case success rate were the same (99.5% vs 97.9% and 98.3% vs 97% respectively). Major adverse cardiac events in RB amounted to 1.7 per cent and for NB to 1.0 per cent (p = ns). The total amount of balloons used in RB was much higher than in the NB group (1.5 +/- 0.6 vs 1.1 +/- 0.3, p = <0.0001). There were neither infection nor positive blood cultures in either group. CONCLUSIONS Reused balloon catheters can be safely used for percutaneous transluminal coronary angioplasty with a high success rate. The total cost of angioplasty can be reduced without a decline in efficacy.

Abstract
UNLABELLED From January 1993 to December 1996, 461 cases (743 lesions) of percutaneous transluminal coronary angioplasty (PTCA) were performed at King Chulalongkorn Memorial Hospital. Seventy eight per cent of the patients were male. Mean age was 61.1 +/- 9.6 yrs and mean ejection fraction was 0.59 +/- 0.18. The indications for PTCA were chronic stable angina (53%), post myocardial infarction (MI) angina (26.6%), unstable angina (17.4%) and acute MI (3%). Emergency PTCA was performed on 15 cases with 5 patients in cardiogenic shock. Fifty four per cent of the cases were performed in single vessel disease, 33 per cent in double vessel disease and 13 per cent in tripple vessel disease. The vessels dilated were the left anterior descending artery (44.2%), right coronary artery (27.8%), left circumflex artery (26.7%), left main (0.9%) and saphenous vein graft (0.4%). Mean balloon size was 2.48 mm. The overall success rate of PTCA, defined as residual diameter stenosis less than 50 per cent, was 91.5 per cent. In addition to PTCA, 123 stent implantations with mean stent size 2.98 mm and 15 rotational athrectomy were done in 114 cases. Complications of PTCA occurred in 32 cases (6.9%). Ten patients (2.2%) had abrupt closure, 1 of these needed emergency coronary bypass graft surgery (CABG). One patient (0.2%) had cerebral embolism with minor residual neurological deficit. One patient (0.2%) had toe gangrene which eventually needed amputation. One patient (0.2%) who presented with acute extensive anterior wall MI and failure of thrombolytic therapy died 8 hours after successful PTCA due to refractory cardiogenic shock. In the patients who also had stent implantation, there were 6 stent misplacements: 3 in the right femoral artery without any complication, 2 were misplacements in the coronary system and 1 dislodged in LM necessitating emergency CABG. CONCLUSION PTCA is the coronary interventional procedure that can be performed with a high success rate and minimal complications.

Abstract
UNLABELLED At King Chulalongkorn Memorial Hospital from July 1994 to December 1996, 123 stents were implanted in 75 males and 25 females. Average age of the patients was 61.3 +/- 9.6 years. Fifty-five per cent of the cases were performed in stable angina, 26 per cent in post myocardial infarction angina. 17 per cent in unstable angina and 2 per cent in acute myocardial infarction. Seventy stents were implanted in the left anterior descending artery, 25 in the left circumflex artery, 27 in the right coronary artery and one stent in the left main. The indications for stent implantation were abrupt closure in thirteen sites, mild dissection in 58, suboptimal dilatation in 19, restenosis in 23 and de novo in 10. Mean size of the stents was 2.99 +/- 0.49 mm and mean inflation pressure was 11.9 atmosphere. Palmaz-Schatz stent was the most commonly used (53.6%) followed by AVE Microstent II (42.3%). There were 3 stents loss in the right femoral artery without any complications. Two stents were misplaced, one stent dislodged in the left main and needed emergency coronary bypass graft surgery. Two patients developed acute stent thrombosis and were successfully reopened with intracoronary urokinase. No patient had major bleeding complication, subacute thrombosis, acute myocardial infarction or death. CONCLUSION Stent implantation can be performed rather safely with a high success rate and minimal complications.

Abstract
To evaluate the results of long Micro Stent II (MS-XL) implantations, 119 MS-XLs were implanted in 102 patients (age, 62.83 years). Nineteen stents (16%) were implanted in saphenous vein grafts; 100 stents (84%) were implanted in native coronary arteries. Twenty-five patients (25%) were treated because of acute myocardial infarction (AMI); 30 patients (29%) because of unstable angina or angina class IV, and 47 patients (46%) because of stable angina. Eighty-six de novo lesions (84%) and 16 restenotic lesions (16%) were treated. Indications for stent implantation include elective, 61 patients (60%); suboptimal balloon angioplasty result, 22 patients (21%); and bailout after balloon angioplasty, 19 patients (19%). Because of residual thrombus after stenting, 27 patients (26%) received abciximab. All patients received ticlopidin for 28 days and acetylsalicylic acid. One hundred and seventeen MS-XLs (98%) were implanted successfully. Additional (shorter) MS-II were implanted in 40 patients (39%). The stented segment length was 45 +/- 20 mm. The minimum lumen diameter increased from 0.5 +/- 0.5 mm before to 2.7 +/- 0.5 mm after stent implantation. The acute gain was 2.2 +/- 0.4 mm. Early clinical events (<4 weeks) include death, 3 (3%); subacute stent thrombosis, 1 (1%); non-Q-wave infarction, 2 (2%); CABG, 1 (1%); vascular complications, 2 (2%). Late clinical events (<6 months) include acute myocardial infarction, 5 (5%); reintervention, 6 (6%); CABG, 1 (1%). The procedural success rate was 88%, and the event free survival at 6 months was 76%. Stenting of long lesions with the MS-XL was successful and associated with an acceptable complication rate.
