Anomalous origin of the left coronary artery from the pulmonary trunk. Clinical features and midterm results after surgical treatment

OBJECTIVE: To report the authors' experience with the anomalous origin of the left coronary artery (AOLCA) from the pulmonary trunk, emphasizing preoperative data, surgical aspects and midterm results of the follow-up. METHODS: Retrospective analysis of 11 patients operated upon at the Royal Brompton Hospital from October, 84 to April, 97. RESULTS: Nine infants had heart failure (HF) and two other children presented with dyspnea and chest pain. All had ECG changes. The echocardiogram identified the anomalous origin of the coronary artery in 7 (64%) patients and hemodynamic studies were performed in 7 patients. All infants were operated upon between the 2nd and 10th month of life. Six patients were treated with aortic reimplantation of the left coronary artery, whereas five were operated upon according to the Takeuchi technique. All patients are alive, with clear improvement of the ECG changes and ventricular function, as evaluated by echocardiography. Two patients operated upon according to the Takeuchi technique required additional surgery due to severe supravalvular pulmonary stenosis. CONCLUSION: AOLCA is a rare disease. Most patients show early signs of severe HF associated with ECG findings. Surgical therapy must be instituted early in the disease, preferentially through aortic implantation of the anomalous coronary artery, with a high possibility of success. Shortly after surgery, clinical and ECG improvement, as well as normalization of left ventricular function, should be expected.

Prevalence of hypertension in the urban population of Catanduva, in the State of São Paulo, Brazil

OBJECTIVE: To study the prevalence of systemic hypertension and its control in the population of Catanduva, in the state of São Paulo, Brazil. METHODS: We carried out a randomized cross-sectional population-based study of the urban population of Catanduva with individuals above 18 years of age (688 individuals accounting for 0.9% of the referred population). We interviewed study participants to analyze the major qualitative and quantitative variables that could influence the hypertensive scenario and the risk for systemic hypertension. Blood pressure was measured through the indirect method according to the III Consenso Brasileiro de Hipertensão (III Brazilian Consensus on Hypertension), which established blood pressure levels > or = 140/90 mm Hg as hypertensive. RESULTS: The prevalence of systemic hypertension was higher in individuals with: (1) history of hypertension (p<0.0001); (2) diabetes mellitus (p=0.05); (3) body mass index (B. M. I) > or = 25 kg/m² (p<0.001); (4) low educational level (p<0.0001); (5) familial income ranging from 1 to 5 minimum wages (p<0.05); (6) unmarried status (divorced/separated and widow(er)s) (p<0.0001). Of the interviewed individuals, 27.6% (p=0.05) had blood pressure levels under control. CONCLUSION: Our study showed that the prevalence of systemic hypertension was 31.5%, and that 27.6% of the individuals interviewed had blood pressure levels under control at the time of the interview.

Concomitant Use of Glycoprotein IIb/IIIa Inhibitor and Streptokinase after Unsuccessful Rescue Angioplasty

A 38-year-old man with acute myocardial infarction in the lower wall affecting the right ventricle underwent thrombolytic treatment with streptokinase. Approximately 2 hours after the thrombolytic treatment started, he presented with signs of coronary reocclusion. He underwent emergency cineangiocoronariography that revealed that his right coronary artery was completely occluded by a clot. He unsuccessfully underwent angioplasty and stent implantation. After the concomitant use of glycoprotein IIb/IIIa inhibitor, coronary TIMI III flow was achieved without additional dilations, and he was discharged from the hospital 5 days later with no further complications.

Avaliação das pressões sistólica, diastólica e pressão de pulso como fator de risco para doença aterosclerótica coronariana grave em mulheres com angina instável ou infarto agudo do miocárdio sem supradesnivelamento do segmento ST

OBJETIVO: Avaliar se as pressões, medidas na raiz da aorta, são fatores de risco para doença aterosclerótica coronariana grave em mulheres com angina instável ou infarto agudo do miocárdio sem supradesnivelamento do segmento ST (AI/IAMSS). MÉTODO:As pressões, assim como os fatores de risco para doença arterial coronariana (DAC) foram prospectivamente coletados de março/1993 a agosto/2001 em 593 mulheres com diagnóstico de AI/IAMSS submetidas à cinecoronariografia. Lesões coronarianas definidas como graves estenoses > 70%. RESULTADOS: Idade média de 59,2±11,2 anos, significantemente mais alta nas pacientes com DAC: 61,9 ± 10,8 anos vs 56.4 ± 10,8 anos; tabagismo, diabetes e climatério foram mais freqüentes nas pacientes com DAC. As médias das pressões sistólica e arterial média foram iguais nos dois grupos, entretanto as médias das pressões diastólicas do ventrículo esquerdo (17.6 ± 8.7 x 15.1 ± 8.1, p=0.001) e da pressão de pulso aórtica foram significantemente maiores nas pacientes com DAC (75.5 ± 22 x 70 ± 19, p=0.002), enquanto a média da pressão diastólica aórtica foi significantemente mais alta nas pacientes sem DAC (75.3 ± 17.5 x 79.8 ± 16, p=0.003). Na análise multivariada a pressão de pulso > 80 mmHg e pressão sistólica > 165 foram independentemente associadas a DAC com razão de chance de 2.12 e 2.09, p<0.05, respectivamente. CONCLUSÃO: A doença arterial coronariana está associada à pressão de pulso mais elevada e pressão diastólica mais baixa em mulheres com AI/IAMSS. Embora a média da pressão sistólica não tenha se associado com DAC, valores dicotomisados de pressão de pulso > 80 mmHg e pressão sistólica > 165 mmHg determinaram risco duas vezes maior de lesão coronariana grave.
