Description of intervention(s) / exposure
Residual significant coronary artery disease after percutaneous coronary intervention (bloooan angioplasty and/or stent imlantation) will be measured by using predefined residual syntax score and syntax revascularization index.. After that the effect of these meausrements on cardiovascular outcomes will be observed for minimum 4 years after the last performed intervnetion

Outcomes
Primary outcome [1] 305826 0
Total mortality, total mortality will be determined by examining medical and hospital records.
Timepoint [1] 305826 0
at the end of 4 years after the last PCI performed, due to it's a retroprospective study, definite visit dates could not be established
Primary outcome [2] 305827 0
Composite end point of cardiovascular mortality, non fatal myocardial infarction and non fatal stroke. This end point will be measured by using hospital records and telephone or face to face contact with patients or first degree relatives.
Timepoint [2] 305827 0
at the end of 4 years after the last PCI performed, due to it's a retroprospective study, definite visit dates could not be established
Secondary outcome [1] 346690 0
Repeat coronary revascularization. This includes any unplanned subsequent coronary intervention after the index procedure. it will be measured by examining health records, patients files and related documents. also if available telephone or face to face contact with patients or first degree relatives will be sought.

Secondary outcome [2] 346691 0
Hospitalization due to cardiovascular causes. This includes any hospitalization due to cardiovascular causes after the index procedure. If the reason for hospitalization is one of the components of primary composite end points then it will be classified under primary end point. . it will be measured by examining health records, patients files and related documents. also if available telephone or face to face contact with patients or first degree relatives will be sought.

Statistical methods / analysis
Annual incidence of total mortality after PCI was 5.9% in previous studies. Expected incidence in study population is % 2. with alpha value 0.05 and power 80% calculated sample size is 230.
t-test and chi-square test will be used to compare groups. Kaplan Meier estimates of survival will be used to analyze mortality rates. Cox proportional hazard ratio will be used to determine independent variables affecting primary outcomes.
