[Early ST resolution after successful primary PCI is related to a favorable outcome in ST elevated AMI patients].

OBJECTIVE: To analyze the relationship between the early ST resolution magnitude and TIMI flow, MACE and the cardiac function in ST elevated AMI (STEMI) patients after successful primary PCI. METHODS: A total of 120 consecutive patients with STEMI underwent primary PCI within 12 hours after the onset of chest pain were enrolled in this study, the ST segment resolution was calculated and the patients were divided into group A (n = 81, Sigma STE resolved > or = 50%) and group B (n = 39, Sigma STE resolved < 50%). TIMI flow after PCI, clinical events up to 30 days post PCI and cardiac function 30 days post PCI were assessed. RESULTS: LVEF was higher in group A than that of group B (58.6% +/- 7.1% vs. 50.5% +/- 7.1%, P < 0.05). There are fewer patients with Killip III and IV in group A than in group B (1.2% vs. 12.8%, P < 0.05). The incidence of in-hospital MACE was also significantly less in group A than in group B (0 vs. 7.7%, P < 0.001). As expected, there were more patients with TIMI 3 flow (95.1% vs. 79.5%, P < 0.05) and fewer TIMI 2 (4.9% vs. 20.5%, P < 0.05) flow post PCI in group A than in group B and all 3 patients with MACE were group B patients with TIMI 2 flow. CONCLUSION: Early ST resolution post PCI represents improved myocardial perfusion and function and is related to a favorable clinical outcome in STEMI patients.

[The long-term results percutaneous transluminal angioplasty and stenting in atherosclerotic renal artery stenosis].

OBJECTIVE: To evaluate the safety, as well as short term and long term effect of percutaneous angioplasty and stenting in atherosclerotic renal artery stenosis. METHODS: A total of 150 consecutive patients with atherosclerotic renal artery stenosis (ARAS) undergoing percutaneous transluminal renal angioplasty (PTRA) and stenting in a period of 6 years were followed up. Blood pressure, renal function before and after the procedure were monitored through-out the follow up years. Renal artery restenosis was tested with ultrasound and Doppler 6-9 months after the procedure. Clinically drive repeat angiogram was done in some patients. RESULTS: 96% of the patients had coronary artery disease and 54% triple vessel disease. A total of 174 renal arteries were found to have severe ARAS in these 150 patients. Procedure success rate was 99.3% with only 1 failure. 3 total occluded renal artery were not attempted, with a total of 170 renal arteries receiving PTRA and stenting. There was no immediate complication such as death, renal artery rupture or acute closure. 145 patients were clinically followed up, with a follow-up rate of 98.6%, and a follow up time between 7 months and 5 years. During follow-up, another 2 patients died in addition to the 3 died in the hospital. All of them died of cardiovascular disease. As to blood pressure, 66 patients among 101 with refractory hypertension and 20 among 42 with well controlled hypertension got improved in 6-9 months of follow up, with an improvement rate of 60.1%. These effects were kept throughout the follow up years. Most of the patient's renal function kept stable and a small number of patient's serum creatine level ameliorating. Renal artery restenosis was found in 10 among the 166 renal vessels undergoing ultrasound examination, with a restenosis rate of 6.0%. CONCLUSION: PTRA and stenting in ARAS patients with coronary artery disease are safe and effective, most of the patient's blood pressure can be controlled and renal function can be kept stable. Restenosis rate is quite low and acceptable.
