Takotsubo cardiomyopathy in a 90-year-old Chinese man / 中华医学杂志(英文版)

A 90-year-old Chinese man was transferred to the Emergency Department of the Affiliated Shantou Hospital of Sun Yat-sen University for treatment of an acute myocardial infarction. He suffered chest pain with three days of cough, dyspnea and fever. A diagnosis of Takotsubo cardiomyopathy was made in normal coronary arteries from urgent coronary angiography and characteristic apical dyskinesis and basal hyper contractility in left ventriculography. The patient died from severe multi-organ failure on the second day of hospitalization.

Correlation between pressure-derived coronary collateral flow and Rentrop grade after primary percutaneous intervention of acute myocardial infarction / 南方医科大学学报

<p><b>OBJECTIVE</b>To analyze the correlation between pressure-derived collateral coronary flow (PDCF) and Rentrop grade of patients with acute myocardial infarction (AMI).</p><p><b>METHODS</b>PDCF, determined by the ratio of P(w)/P(a), was measured in 29 patients with AMI of the first onset who received primary percutaneous coronary intervention (PCI) within 12 h after the onset. Sufficient collateral flow (group A, n=19) was defined as PDCF>0.24 and insufficient collateral flow (group B, n=10) as PDCF< or =0.24. Rentrop grade of the collateral flow was evaluated by coronary angiography. Echocardiography was performed on the 3rd and 30th day after PCI. The left ventricular ejection fraction, end-systolic and end-diastolic volumes, and the related indexes were obtained.</p><p><b>RESULT</b>Rentrop grade was significantly related to PDCF (r=0.75, P<0.01), but a wide range of PDCF was observed in patients with Rentrop grade< or =1.</p><p><b>CONCLUSION</b>PDCF measurement allows quantitative evaluation of the collateral flow in patients with AMI.</p>

Clinical observations of emergent PTCA combined with Lipo-PGE_1 for the young patients with acute myocardial infarction / 中国基层医药

Objective To evaluate the clinical effect in the treatment of the young patients(≤45 years old) with acute myocardial infarction(AMI)underwent emergent percutaneous transluminal coronary angioplasty(PTCA) combined with Lipo-PGE_1.Methods 39 patients with AMI(paroxysm within 12 hours),were underwent emergent PTCA(coronary stem performed in some patients),including 18 cases which were treated combined with Lipo-PGE_1 in the mean time.And the clinical efficacy and the results of short-period follow-up were recorded.Results The in- farctive vasculars were re-open in 37 patients(23 cares were routinely placed translunrinal srents),and the successful rate was 94.9 %.Those who also used Lipo-PGE_1 were re-open in 17 patients.The successful rate was 94.4 %,their ST segments on EKG 30 minutes after operations reduced significantly than that of patients who did not use Lipo- PGE_1,their cardial functions were also improved significantly 24 hours after operations and no side effects on blood pressure and heart rate were observed.Conclusion The emergent PTCA combined with Lipo-PGE_1 for acute my- ocardial infarction can protect the cardial function and show a better early therapy effect.

The clinical significance on the change of ST segments after direct percutaneous transcoronary angioplasty com- bined with Lipo-PGE1 in treating acute myocardial infarction / 中国实用内科杂志

Objective The aim of the study is to approach the clinical significance of the change of ST segments after di- rect percutaneous transcoronary angioplasty(PTCA) combined with Lipo-PGE_1 in treating Acute Myocardial Infarction (AMI).Methods The change of the ST segments on EKG of 76 patients with AMI are observed in 30 minutes after un- derwent direct PICA combined with Lipo-PGE_1,and the relations are analyzed that are prospectively to their therapy effect,the degree of injured cardiac muscle,the cardial functions,and the prognosis.Results The patients who treated with the PCTA combined with Lipo-PGE_1 ST segments on EKG 30 minutes after operations reduced significantly,cardiac muscle is injured lowly,their cardial functions are better.Conclusion The change of ST segments after direct percutane- ous transcoronary angioplasty (PTCA) combined with Lipo-PGE_1 in treating acute myocardial infarction is one of the guide line to estimate the perfnsion of cardiac muscle,and to estimate prognosis farther.
