Methods: A total of 136 patients older than 60 years with STEMI who received successful PCI were included in this study. The patients were classified in 2 age groups: patients ≥75 years and <75 years of age. The extent of coronary artery lesions was measured by quantitative coronary artery angiography (QCA). Subjects were tracked for subsequent cardiovascular events: cardiac death, myocardial infarction, heart failure, percutaneous coronary intervention, coronary artery bypass and stroke. Results: Though the older group had a higher prevalence of adverse baseline characteristics and lower final TIMI flow than patients<75y (P<0.05), the procedural success did not make difference between the two groups. In 12 months follow-up of 136 study participants, there occurred 39 CV events : cardiac death (five patients), heart failure (nineteen patients), and stroke (six patients). Three patients received coronary bypass grafts and six patients underwent PCI. Heart failure and overall cardiovascular event rates were higher in older patients compared with those in patients<75y. The main adverse clinical events (MACE) for the old group were a little higher comparing with the younger in 12-month follow-up (P=0.029 6 and P=0.043 4). Multivariate cox analysis identified that a diagnosis of diabetes (HR 2.495, 95%CI 1.224 to 5.083, P= 0.011 8) and time from symptom(HR 1.450, 95%CI 1.143 to 1.841, P= 0.008 2) to PCI as independent predictors of CV events after adjustment of all entered baseline variables. Conclusion: Our study suggests that drug-eluting stent implantation in older patients with acute ST elevation myocardial infarction has high initial procedural success rates despite having more severe baseline risk characteristics, and to shorten the time from symptom onset to PCI may decrease cardiovascular events in old patients following PCI.展开更多

METHODS： From February 2004 to May 2005, 100 patients （63 men, 37 women） underwent angiography performed with a 16-scanner multi-detector row CT unit （Toshiba, Aquilion 16）. All images were analyzed on a workstation （AZE Ltd, Virtual Place Advance 300）. The distance from the root of the IMA to the bifurcation of the LCA was measured by curved multi-planar reconstruction on a workstation. RESULTS： The IMA could be visualized in all the cases, but the LCA was missing in two patients. The mean distance from the root of the IMA to the root of the LCA was 42.0 mm （range, 23.2-75.0 mm）. There were no differences in gender, arterial branching types, body weight, height, and body mass index. CONCLUSION： Volume-rendered 3D-CT is helpful to assess the vascular branching anatomy for laparoscopic surgery.展开更多

METHODS: According to age, 403 patients operated on for CRC in our department were divided into group A (< 70 years old) and group B (≥ 70 years old) and analyzed statistically. RESULTS: Rectal localization prevailed in group A (31.6% vs 19.7%, P = 0.027), whereas the percentage of R0 resections was 77% in the two groups. Comorbidity rate was 46.2% and 69.1% for group A and B, respectively (P < 0.001), with a huge difference as regards cardiovascular diseases. Overall, postoperative morbidity was 16.9% and 20.8% in group A and B, respectively (P = 0.367), whereas mortality was limited to group B (4.5%, P = 0.001). In both groups, patients who suffered from postoperative complications had a higher overall comorbidity rate, with preexisting cardiovascular diseases prevailing in group B (P = 0.003). Overall 5-year survival rate was significantly betterfor group A (75.2% vs 55%, P = 0.006), whereas no signif icant difference was observed considering disease-specif ic survival (76.3% vs 76.9%, P = 0.674). CONCLUSION: In spite of an increase in postoperative mortality and a lower overall long-term survival for patients aged ≥ 70 years old, it should be considered that, even in the elderly group, a signif icant number of patients is alive 5 years after CRC resection.展开更多
