The study is planned as a descriptive study to determine the complications and affecting factors in patients undergoing percutaneous coronary intervention.
The sample of the study is 742 patients who undergo percutaneous coronary intervention in cardology department of a private hospital in years 2010-2011. The data of the study were collected through a questionnaire prepared by the researchers. The data about the patients are obtained by means of interviewing with patients, observations and patient files’ investigation. For the study, written permission is obtained from the institute and verbal permission is obtained from the patients. The data is evaluated using number and percentage calculations in SPSS 16.0 software.
Out of 742 patients who followed in this study, 82,2% of them are between the ages of 45-75 and 69% of them are males. 68.2% of the patients have at least one more chronic disease except coronary artery disease. 59,4% of the patients were performed coronary angiography whereas 40,6% undergone percutaneous transluminal angioplasty and stent application. In the post operative period, in 9.8% of the patients, bleeding and in 6.2% of the patients, hematoma was observed at the puncture site. Hematoma was developed within the first hour after the procedure in 39,1% of the patients who developed hematoma. In the post operative period, 90.8% of the patients were followed with pressure dressing and sandbag. The ratio of the patients followed with only pressure dressing is 9,2%. The difference between the patients’ age and development of bleeding and hematoma was found statistically significant (p<0,05) whereas sex, having an additional chronic disease and pressure method after the operation and development of bleeding and hematoma was not found statistically significant. The amount of heparin used during the process and the dose of clopidogrel administered to the patient on operation day and development of bleeding and hematoma was found statistically significant (p<0,05).
According to the results of our study; the patient's age, the amount of anticoagulant and antithrombotic agent used before, during and after the percutaneous coronary intervention affects the development of bleeding and hematoma.
