Abstract Objective: To evaluate the association of pulse pressure (PP) with mortality and major adverse cardiac events (MACE) in one-year period after anterior ST-elevation myocardial infarction (A-STEMI). Methods: A total of 261 consecutive patients whose blood pressure was measured with the aid of a catheter before primary percutaneous coronary intervention (PPCI) between August 2016 and February 2017 were included in the study. The patients were divided into three groups according to pulse pressure (PP) (Group 1, PP<35 mmHg; Group 2, 35≤PP≤50 mmHg; Group 3, PP>50 mmHg). Results: The mean age of the patients was 63.4±14.1 years, and 206 of them were male. The groups were similar in terms of age and diastolic blood pressure (DBP). The ratio of female patients in Group 1 was higher, and their systolic blood pressure (SBP) was lower than those from the other groups (P=0.005 vs. P=0.042). The rates of MACE and mortality were higher in Group 1. The predictive PP values were calculated to be 42.5 mmHg for development of MACE and 41.5 mmHg for mortality. One-year survival ratio was worse in Group 1 than in the others according to Kaplan-Meier analysis (P<0.001). Conclusion: The values of PP which was measured intra-aortically in patients with A-STEMI were associated with mortality and MACE in the one-year follow-up period.

Resumo Fundamento: O escore de risco GRACE (SG) é um sistema com significado prognóstico para pacientes com infarto do miocárdio sem supradesnivelamento do segmento ST (IMSSST). Objetivo: Determinar se a espessura da gordura epicárdica (EGE) ao final da sístole ou da diástole é mais associada com pacientes de IMSSST de alto risco de acordo com o SG. Métodos: Este estudo avaliou 207 pacientes com IMSSST desde outubro de 2012 a fevereiro de 2013, sendo 162 deles incluídos no estudo (115 homens, idade média: 66,6 ± 12,8 anos). Mediu-se a EGE ao final da sístole e da diástole com métodos ecocardiográficos. Pacientes com alto SG intra-hospitalar (SG > 140) foram classificados como grupo SG-A, enquanto os outros foram classificados como grupo de risco baixo-a-moderado (grupo SG-BM). Resultados: As pressões arteriais sistólica e diastólica dos pacientes SG-A foram mais baixas do que as dos pacientes SG-BM, sendo a frequência cardíaca média mais alta nesse grupo. A EGE ao final da sístole e a EGE ao final da diástole foram significativamente mais altas no grupo SG-A. A avaliação ecocardiográfica dos ventrículos direito e esquerdo mostrou fração de ejeção significativamente reduzida em ambos os ventrículos no grupo SG-A. Observou-se maior correlação entre SG e EGE ao final da diástole (r = 0,438). Conclusão: A EGE ao final da sístole e a EGE ao final da diástole mostraram-se aumentadas no grupo SG-A. Entretanto, a EGE ao final da diástole apresentou melhor correlação com o SG do que a EGE ao final da sístole.

Abstract Background: GRACE risk score (GS) is a scoring system which has a prognostic significance in patients with non-ST segment elevation myocardial infarction (non-STEMI). Objective: The present study aimed to determine whether end-systolic or end-diastolic epicardial fat thickness (EFT) is more closely associated with high-risk non-STEMI patients according to the GS. Methods: We evaluated 207 patients who had non-STEMI beginning from October 2012 to February 2013, and 162 of them were included in the study (115 males, mean age: 66.6 ± 12.8 years). End-systolic and end-diastolic EFTs were measured with echocardiographic methods. Patients with high in-hospital GS were categorized as the H-GS group (in hospital GS > 140), while other patients were categorized as the low-to-moderate risk group (LM-GS). Results: Systolic and diastolic blood pressures of H-GS patients were lower than those of LM-GS patients, and the average heart rate was higher in this group. End-systolic EFT and end-diastolic EFT were significantly higher in the H-GS group. The echocardiographic assessment of right and left ventricles showed significantly decreased ejection fraction in both ventricles in the H-GS group. The highest correlation was found between GS and end-diastolic EFT (r = 0.438). Conclusion: End-systolic and end-diastolic EFTs were found to be increased in the H-GS group. However, end-diastolic EFT and GS had better correlation than end-systolic EFT and GS.

FUNDAMENTO: A previsão de gravidade ou complexidade da doença arterial coronariana (DAC) é valiosa devido ao aumento do risco de eventos cardiovasculares. Embora a associação entre o escore do cálcio arterial coronariano (CAC), e a gravidade da DAC pelo escore Gensini não tenha sido utilizado, já foi anteriormente demonstrado. Não há informações sobre a associação entre o escore do CAC total e a complexidade da DAC. OBJETIVOS: Investigar a associação entre a gravidade ou complexidade da doença arterial coronariana (DAC), avaliada pelo escore Gensini e SYNTAX (SS), respectivamente, e o escore do cálcio arterial coronariano (CAC), um método não invasivo para avaliação de DAC em pacientes sintomáticos com DAC significativa. MÉTODOS: Duzentos e quatorze pacientes foram incluídos. A pontuação total do CAC foi obtido antes da angiografia. A severidade e complexidade da DAC foram avaliadas pelo escore Gensini e SS, respectivamente. Foram analisadas as associações entre parâmetros clínicos e angiográficos e o escore total do CAC. RESULTADOS: A mediana do escore total do CAC foi de 192 (23,0-729,8), e correlacionou-se positivamente com ambos os escores Gensini (r: 0,299, p < 0,001) e ES (r: 0,577, p < 0,001). Na análise multivariada associou-se independentemente com a idade (ß: 0,154, p: 0,027), sexo masculino (ß: 0,126, p: 0,035) e ES (ß: 0,481, p < 0,001). A análise da curva ROC (Receiver Operating Characteristics) revelou um valor de corte > 809 para ES > 32 (tercil de SS alto). CONCLUSÃO: Em pacientes sintomáticos com DAC significativa, o escore total de CAC foi independentemente associado com SS e os pacientes com SS > 32 podem ser detectados através de escore Agatston alto.

BACKGROUND: Prediction of severity or complexity of coronary artery disease (CAD) is valuable owing to increased risk for cardiovascular events. Although the association between total coronary artery calcium (CAC) score and severity of CAD, Gensini score was not used, it has been previously demonstrated. There is no information about the association between total CAC score and complexity of CAD. OBJECTIVES: To investigate the association between severity or complexity of coronary artery disease (CAD) assessed by Gensini score and SYNTAX score (SS), respectively, and coronary artery calcium (CAC) score, which is a noninvasive method for CAD evaluation in symptomatic patients with accompanying significant CAD. METHODS: Two-hundred-fourteen patients were enrolled. Total CAC score was obtained before angiography. Severity and complexity of CAD was assessed by Gensini score and SS, respectively. Associations between clinical and angiographic parameters and total CAC score were analyzed. RESULTS: Median total CAC score was 192 (23.0-729.8), and this was positively correlated with both Gensini score (r: 0.299, p<0.001) and SS (r: 0.577, p<0.001). At multivariate analysis, it was independently associated with age (ß: 0.154, p: 0.027), male gender (ß: 0.126, p: 0.035) and SS (ß: 0.481, p< 0.001). Receiver-operating characteristic (ROC) curve analysis revealed a cut-off value > 809 for SS >32 (high SS tertile). CONCLUSION: In symptomatic patients with accompanying significant CAD, total CAC score was independently associated with SS and patients with SS >32 may be detected through high Agatston score.
