Background — There are few data on the change in the profile of cath lab patients over long time intervals.
Methods — We retrospectively analysed our cath lab records, patient charts, in terms of demographic variables, clinical and laboratory characteristics in a thousand patients (499 patients in 1998 January-March, 501 patients in 2006 January-March).
Results — Mean age was significantly higher in the 2006 cohort (57.5 ± 11 vs. 62.2 ± 10.8, P < 0.001). Gender was similar in both cohorts (men 68.5% vs. women 69.9%, P = 0.65). Both hypertension and diabetes mellitus were more prevalent in the 2006 cohort (613% vs. 49.3 and 30.3 vs. 17.6 respectively, P < 0.001 for both). Smoking rates (past or active) did not differ between the cohorts. Rates of normal or near normal coronary angiograms were somewhat elevated in both cohorts (36.7% in 1998 and 39.1% in 2006). Rates of multivessel disease (2-3 vessel disease) tended to increase and rates of single-vessel disease tended to decrease from the 1998 cohort to the 2006 cohort (27.7% to 34.4% and 35.7% to 26.7%, P = 0.006). The number of percutaneous coronary interventions (PCI) performed increased with a borderline statistical significance in the 2006 cohort (32% vs. 38.5%, P = 0.053).
Conclusions — Our data indicates that today interventional cardiologists face an older and more severely diseased cath lab patient population compared with a decade earlier. In comparison with 1998, more PCIs were performed.
