ABSTRACT
Abstract

Background:

Myocardial performance index (MPI), demonstrates both systolic and diastolic functions of the left ventricle. Presystolic wave (PSW) is frequently detected on Doppler examination of the left ventricular outflow tract and possible mechanism of PSW is impaired LV compliance and left ventricular stiffness.

Objective:

To investigate the relationship between PSW and MPI in type 2 diabetic patients.

Method:

A total of 129 type 2 diabetic patients were included in this study. Patients were divided into two groups according to the presence of PSW on Doppler echocardiography. There were 90 patients (38 male, mean age 57.77 ± 10.91 years) in the PSW-positive group and 39 patients (13 male; mean age 55.31 ± 11.29 years) in the PSW-negative group. The p values of < 0.05 were considered statistically significant.

Results:

MPI was higher in PSW- positive group (0.63 ± 0.17vs 0.52 ± 0.13, p < 0.001). In addition, subclinical left ventricle dysfunction (LVD) was higher in the PSW- positive group (p = 0.029). Univariate analysis showed that the presence of PSW associated with abnormal MPI (p = 0.031). Pearson correlation analysis showed that PSW velocity correlated with MPI (r 0.286, p = 0.006).

Conclusion:

Presence of the PSW on Doppler examination was associated with subclinical LV dysfunction in patients with DM type 2. This easy-to-perform echocardiographic parameter may be related to subclinical LVD among patients with type 2 DM.
RESUMO
Resumo Fundamento O índice de performance miocárdica (IPM) avalia as funções sistólica e diastólica do ventrículo esquerdo. A onda pressistólica (OPS) é geralmente detectada no exame Doppler da via de saída do ventrículo esquerdo e seus possíveis mecanismos são complacência prejudicada e rigidez do ventrículo esquerdo.

Objetivo:

Investigar a relação entre OPS e IPM em pacientes com diabetes tipo 2.

Método:

129 pacientes com diabetes tipo 2 foram incluídos no estudo. Os sujeitos foram alocados em dois grupos, com base na presença de OPS no exame ecocardiográfico com Doppler. Foram incluídos 90 pacientes (38 homens, idade média 57,77 ± 10,91 anos) no grupo OPS-positiva e 39 pacientes (13 homens; idade média 55,31 ± 11,29 anos) no grupo OPS-negativa. Valor de p < 0,05 foi considerado para significância estatística.

Resultados:

O IPM foi mais alto no grupo OPS-positiva (0,63 ± 0,17 vs 0,52 ± 0,13, p < 0,001). Além disso, a disfunção ventricular esquerda subclínica (DVE) foi maior no grupo OPS-positiva (p = 0,029). Análise univariada mostrou associação de OPS com IPM anormal (p = 0,031), assim como o coeficiente de correlação de Pearson mostrou correlação entre velocidade de OPS e IPM (r 0,286, p = 0,006).

Conclusão:

Presença de OPS na ecocardiografia com Doppler foi associada à DVE subclínica em pacientes com diabetes tipo 2. Esse exame ecocardiográfico de fácil execução pode ser relacionado à DVE subclínica entre pacientes com diabetes tipo 2.
