Prevalence of cardiac allograft vasculopathy assessed with coronary angiography versus coronary vascular ultrasound and virtual histology.

BACKGROUND: Cardiac allograft vasculopathy (CAV) is a major factor limiting long-term survival after heart transplantation (HT). The purpose of this study was to characterize the coronary artery structure and to determine the prevalence of vasculopathy after HT, comparing the sensitivity of coronary angiography with that of intravascular ultrasound (IVUS) and virtual histology (VH). METHODS: A prospective recruitment cross-sectional study was performed in 31 adult HT recipients including 22 men and, 9 women of overall mean age of 45.2 ± 12.6 years at an average of 3.7 ± 3.7 years after transplantation. They underwent simultaneously coronary angiography and IVUS assessment of the left anterior descending coronary artery. We investigated histological composition of the intima. Final data were analyzed using parametric and nonparametric tests. RESULTS: IVUS discovered the presence of CAV among 17/31 (54.8%) patients versus coronary angiography in 10 (32.3%; P = .009). The histological composition of the intima as assessed with IVUS VH was 26.1% fiber, 8.7% necrotic core, 5.7% calcium, and 4.3% lipid. There was no significant association between preexistent risk factors and the presence of CAV. There was a correlation between time elapsed since HT and CAV development. CONCLUSION: Time elapsed since HT is the most important risk factor for the development of CAV. Its prevalence almost doubled when measured with IVUS in contrast with angiography. IVUS was thus shown to be a more sensitive diagnostic tool compared with coronary angiography.

[Cardiac transplantation: economizing cyclosporin A by including ketoconazole in the immunosuppressive schedule]. / Trasplante cardíaco: ahorro de ciclosporina "A" mediante la asociación de ketoconazol al esquema inmunosupresor.

Use of cyclosporin A has improved survival in patients submitted to cardiac transplantation. However, high cost of cyclosporin poses a problem for many patients in Chile. Ketoconazole is able to reduce hepatic metabolism of cyclosporin and thus prolong therapeutic levels. A 74 to 82% reduction in cyclosporin requirements was obtained in a cardiac transplant patient by adding ketoconazole. No renal damage was detected. Therefore, this drug association may help extend cardiac transplantation programs in Chile.

[Acute myocardial infarction: thrombolytic efficacy of 500.000 UI of streptokinase combined with heparin]. / Infarto agudo del miocardio: eficacia trombolítica de 500.000 UI de estreptokinasa asociada a heparina.

Most reports concerning the use of streptokinase (SK) for thrombolysis in myocardial infarction (MI) have employed doses over 1,000,000 units. We evaluated the efficacy of a dose of 500,000 U in 40 patients with acute MI who received full heparin dose before, during and after SK. Thrombolytic effect, as measured by the protamine neutralized thrombin time was shown to be strong in 60% of cases, moderate in 17% and weak in 22%, and this was not modified by larger SK doses. A patent culprit artery was demonstrated at coronary arteriography performed 3 days after SK in 90% of patients. Only one instance of severe bleeding was observed. Thus, a reduced SK dose in association to heparin provides adequate lytic effect and artery patency rate in patients with MI.
