Abstract

ObjectiveTo measure the impact of cardiac resynchronisation therapy in terms of cardiac ultrasound variables in patients from Latin-American countries. MethodA prospective, multicentre, interventionist study was conducted, in which the eligible patients were those that had a cardiac resynchronisation device implanted for the first time. The primary objective was to assess the changes in size and left ventricular function by means of a cardiac ultrasound carried out prior to implanting the device and in the sixth month. The secondary objectives evaluated were hospital admissions, change in functional class, mortality, quality of life, and an overall assessment of the patient using a combined clinical score based on these factors. ResultsA total of 75 subjects were analysed in order to complete the primary objective. The mean age was 63.7 years; 21.3% were female, and 30.7% had ischaemic heart disease. At the sixth month, the left ventricular end-diastolic and systolic volume decreased by a mean of 37.6 ml and 37.8 ml, respectively. The left ventricular ejection fraction increased by a mean of 11%. The combined clinical score showed an improvement in 86.4% of the patients in the sixth month after the implantation of the synchronisation device. ConclusionsA reverse remodelling of the left ventricle was observed, as well as an improvement in the clinical stage of patients with heart failure and left ventricular systolic dysfunction that received cardiac resynchronisation treatment in the setting of routine clinical practice.
