Correlation between C-Reactive Protein in Peripheral Vein and Coronary Sinus in Stable and Unstable Angina

Background High sensitivity C-reactive protein (hs-CRP) is commonly used in clinical practice to assess cardiovascular risk. However, a correlation has not yet been established between the absolute levels of peripheral and central hs-CRP. Objective To assess the correlation between serum hs-CRP levels (mg/L) in a peripheral vein in the left forearm (LFPV) with those in the coronary sinus (CS) of patients with coronary artery disease (CAD) and a diagnosis of stable angina (SA) or unstable angina (UA). Methods This observational, descriptive, and cross-sectional study was conducted at the Instituto do Coração, Hospital das Clinicas, Faculdade de Medicina, Universidade de São Paulo, and at the Hospital Beneficência Portuguesa de Sao Paulo, where CAD patients referred to the hospital for coronary angiography were evaluated. Results Forty patients with CAD (20 with SA and 20 with UA) were included in the study. Blood samples from LFPV and CS were collected before coronary angiography. Furthermore, analysis of the correlation between serum levels of hs-CRP in LFPV versus CS showed a strong linear correlation for both SA (r = 0.993, p < 0.001) and UA (r = 0.976, p < 0.001) and for the entire sample (r = 0.985, p < 0.001). Conclusion Our data suggest a strong linear correlation between hs-CRP levels in LFPV versus CS in patients with SA and UA.

Transplante cardíaco em amiloidose primária

Cardiac amyloidosis is a disease that highly compromises the survival expectancy after the beginning of the symptomatic phase, usually with sudden death as the final event. The aggression to other organs, although, can make heart transplantation a disputable form of treatment taking into consideration the shortage of organ donors. The aim is to report the evolution with a survival of seven years after heart transplantation and in fair condition of a patient with amyloidosis. One year after the heart transplantation, the patient was referred to renal transplantation also in consequence of the disease aggression. The patient evolution was favorable compared to three other patients also from our service, who died early after the diagnosis. Even considering the multi-systemic nature of amyloidosis, we can accept that in selected patients the heart transplantation is justified, taking into account the very ill prognosis of the disease.

Experience with heterotopic heart transplantation in patients with elevated pulmonary vascular resistance: late follow-up

BACKGROUND Along the past few years the number of papers on heterotopic cardiac transplant has been very scarce in the medical literature, including at the international level; this is particularly true in reference to the long term follow-up of these patients and the reason which led to the presentation of our report. OBJECTIVE To report the initial clinical experience and late evolution of 4 patients undergoing heterotopic heart transplantation, indications for this procedure and its major complications. METHODS The surgeries were performed between 1992 and 2001, and all had as indication for heterotopic transplantation the PVR, which ranged from 4.8 WU to 6.5 WU, with a transpulmonary gradient above 15 mmHg. In the 3rd patient, a direct anastomosis between the pulmonary arteries was performed without the use of a prostetic tube, and a mitral valvuloplasty and a LV aneurysmectomy were performed in the native heart. The immediate immunosuppressive regimens were double, with cyclosporine and azathioprine in the first 3 patients, and cyclosporine and mycophenolate mofetil in the 4th patient. RESULTS One immediate death occurred from graft failure, one death occurred after 2 (1/2) years, from endocarditis in an intraventricular thrombus in the native heart, and a third death occurred 6 years after transplantation, from post-operative complications of the aortic valve surgery in the native heart. The remaining patient is well, 15 years after the transplantation. This patient is in functional class II (NYHA), 6 years after a surgical occlusion of the native heart aortic valve. CONCLUSION Heterotopic heart transplantation results are inferior to those of orthotopic heart transplantation because they present higher RVP. The intraventricular thrombi, in the native heart, which require prolonged anticoagulation, and aortic valve complications, also in the native heart, may require surgical treatment. However, a patients 15-year survival has demonstrated a long-term effectiveness of this option for selected patients.BACKGROUND: Along the past few years the number of papers on heterotopic cardiac transplant has been very scarce in the medical literature, including at the international level; this is particularly true in reference to the long term follow-up of these patients and the reason which led to the presentation of our report.
