To analysis the cardiovascular comorbidities of the patients with proximal femoral fracture, and to explore the correlation between comorbidity and age as well as the length of stay.
2238 patients with proximal femoral fracture form January, 2003 to December, 2013 were investigated. The comorbidities of such patients were analyzed. The correlation of comorbidity and age as well as length of stay (LOS)was explored.
The average age was 68.57, and the average length of stay was 24.07 days. 1768 cases had comorbidities, and 470 cases had NO comorbidity. There were maximum 10 comorbidities in one single patient. The most prevalent comorbidities were essential hypertension (671 cases, 29.98%), coronary heart disease (136 cases, 6.08%), hypovolemic shock (50 cases, 2.23%), arrhythmia (96 cases, 4.29%), diabetes mellitus (type 2) (223 cases, 9.96%), sequela of apoplexy (100 cases, 4.47%), other injures (335 cases, 14.97%) and other comorbidities (157 cases, 7.02%).
The average age and LOS were 61.47 years and 18.5 days in 470 cases (42.00%) without comorbidity, 62.64 years and 20.92 days in 555 cases (24.80%) with one cardiovascular and other comorbidity, 69.25 years and 23.76 days in 380 cases (17.2%) with two comorbidities and 70.66 years and 25.15 days in 370 cases (16.53%) with more than two comorbidities respectively. The average age and LOS were 65.25 years and 27.35 days in 953 cases (42.58%) with cardiovascular comorbidities 54.35 years and 17.42 days in 815 cases (36.42%) with no cardiovascular comorbidities. The increase of age and LOS were correlated to the number of comorbidity which the patient had (P<0.05). Patients with two comorbidities and with more than two comorbidities had no significant difference in age and LOS (P>0.05).
The most prevalent cardiovascular comorbidities in patients with proximal femoral fracture were essential hypertension, coronary heart disease, arrhythmia and hypovolemic shock. As the age increasing, the number of comorbidity and the length of stay also increase. The length of stay of the cases were long with cardiovascular comorbidities than that with other comorbidities.
