Introduction:

Cardiovascular diseases are the leading cause of death in Cuba and most of the developed countries. Two-dimensional speckle tracking echocardiography (2D ST) is a recent technique in the evaluation of cardiac function.

Objectives:

To determine the relationship between myocardial deformation measured by 2D ST and coronary circulation in patients with ischemic heart disease, in the CIMEQ, for 1 year.

Material and method:

An analytical, cross-sectional study was carried out with 55 patients with an indication for coronary angiography who underwent 2D echocardiography and 2D ST study with longitudinal strain measurement (LSM). Two groups significant coronary disease (SCD = 32) and not significant (NSCD = 23) were created. SSPS was used to analyze the results.

Results:

The average age was higher in SCD (55.6 ± 9.3 vs. 61.8 ± 8.8, p = 0.014). Men with SCD (47.3%), hypertensive (SCD = 90.6% and NSCD = 65.2%, p = 0.02) and smokers (SCD = 59.4% and NSCD = 17.4%, p = 0.002) predominated. The most frequent diagnosis was chronic stable angina (87%). Three-vessel disease (75%) prevailed in SCD. The LMS was lower in SCD ([−20.0 ± 3.2 vs. −22.1 ± 3.6, p = 0.035]; AUC = 0.458). There were no differences in LSM according to the number of significantly diseased vessels.

Conclusions:

The results found do not justify the use of 2D ST to discriminate SCD.
