Prevalence of Gastrointestinal Diseases and Treatment Status in Noncardiac Chest Pain Patients

Background and Objectives We evaluated the prevalence of gastroesophageal reflux diseases (GERD) in noncardiac chest pain (NCCP) patients, risk factors for GERD, and status of prescriptions for GERD in Korean population. Subjects and Methods This was a retrospective non-interventional observational nation-wide 45-center study. Patients with a normal coronary angiogram (CAG) and upper gastroendoscopy within 2 years after CAG were enrolled. The prevalence of GERD was examined. Other gastrointestinal diseases including peptic ulcer diseases or gastritis were also examined. Risk factors for GERD were compared between the GERD group and non-GERD group. The ratio of patients medicated for gastrointestinal diseases (antacids or proton-pump inhibitor) was also examined. Results Nine hundred four patients were enrolled. Among the NCCP patients, GERD was present in 436 (48.2%), peptic ulcer disease in 154 patients (17.0%), and gastritis in 659 (72.9%). There was no difference in risk factors for GERD between the GERD and non-GERD patients. Medications for GERD and other gastrointestinal diseases were prescribed in 742 (82.1%) patients. Conclusion GERD was common (42.8%) in Korean NCCP patients and most (82.1%) received the prescription of gastrointestinal medications. No differences were evident in risk factors between GERD and non-GERD patients.

A Typical Case of L-Transposition of the Great Arteries Initially Presented as Complete Atrioventricular Block in Middle-Aged Man

L-transposition of the great arteries (L-TGA) is a rare congenital anomaly and could cause complete atrioventricular (AV) block at relatively younger age. We present a case of 43-year-old male who complained of dizziness due to complete AV block. We confirmed L-TGA using transthoracic echocardiography and cardiac computed tomography. Permanent pacemaker was inserted without complications. No invasive treatment including corrective surgery was performed because patients cardiac function was almost normal and the symptom was completely resolved after pacemaker insertion.

TCT-349 Three-Year Major Clinical Outcomes between First-Generation versus Second-Generation Drug-Eluting Stents in Acute Myocardial Infarction: Propensity Score Matched Analysis

Purpose: There are few clinical outcome data comparing first- versus second-generation drug-eluting stents (DESs) in patients with acute myocardial infarction (AMI) who underwent successful percutaneous coronary intervention (PCI). We investigated the 3-year major clinical outcomes between first- versus second-generation DESs in AMI patients. Methods: From January 2004 to May 2011, a total of 883 AMI patients were enrolled. Patients were excluded if they had: (1) bare-metal stent or other types of DESs (e.g., third generation DESs or Bioabsorbable vascular scaffold) implantation, (2) balloon angioplasty alone, (3) incomplete or invalid data. Finally a total of 749 eligible AMI patients who underwent PCI with first-generation DESs (Paclitaxel- or Sirolimus-eluting stent, n = 386) or second-generation DESs (Zotarolimus or Everolimus-eluting stent, n = 363) were enrolled. To adjust baseline confounders, a propensity score matched (PSM) analysis was performed using the logistic regression model and 2 propensi...

TCT-189 Comparison of 5-year Clinical Outcomes between Stabilized Acute Myocardial Infarction Patients following Percutaneous Coronary Intervention and the Patients with Angina Pectoris

RESULTS There were 1,654 patients in the early discharge group. They were younger than the standard group (60 12 vs 63 13 years; p1⁄40.001) and more likely to be male (81% vs 59%; p1⁄40.001). The early group were less likely to have diabetes (14% vs 18%; p1⁄40.001), there Zwolle score was also less (2.1 1.9 vs 2.8 2.3; p1⁄40.001). The mean length of stay for the early group was 2.6 0.7 vs 6 4.9, p1⁄40.001.
