PATINO, Bonell et al. Frequency and demographic characteristics of patients diagnosed thrombosis coronary stent implantation in a university hospital from January 2011 to December 2012. Rev. Colomb. Cardiol. [online]. 2016, vol.23, n.2, pp.87-95. ISSN 0120-5633.  https://doi.org/10.1016/j.rccar.2015.05.010.

Objective: Establish frequency and demographic characteristics of patients with diagnosis of coronary stent thrombosis into Hospital Universitario Clínica San Rafael (HUCSR) over a time period of 24 months. Methods: Retrospective and descriptive Study. Clinical records were reviewed for patients older 18 with diagnosis of coronary stent thrombosis, confirmed through coronary arteriography made in HUCSR-Hemodinamics department on urgency, inpatient or outpatient, on a 24-month time period. Results: 890 arteriography and angioplasty plus stent implantation were performed. Frequency of coronary stent thrombosis was of 2.7%, in 70% of the cases male patients were younger on average than women (63.0 years old vs 70.3 years old). Most commonly described associated diseases were arterial hypertension (65%), diabetes mellitus (25%), and chronic kidney disease (10%). The average left ventricular ejection fraction was 38.7%. Incidentally, while data were being recollected, the stent stenosis was found in too many patients, with a frequency of 14.5% (n = 36) on patients who underwent angioplasty and stent implantation. Conclusions: Coronary stent thrombosis frequency is similar to reports around the world. This complication is more frequent in male patients, onset age was younger and associated with worse left ventricular function. High coronary stent stenosis frequency required more studies.
