Cases Analysis Of Coronary Heart Disease With Atrial Fibrillation

OBJECTIVE: To observe the clinical features in patients who were diagnosed as coronary heart disease(CHD) with atrial fibrillation(AF); METHOD: Based on the data of the inpatients who were diagnosed as CHD with AF in our CCU room and in the year of 2006. There were 19 inpatients whose data were complete and accord to the conditions talked previously, and in which there were 15 patients(78.9%) with chronic stable coronary heart disease, while the left 4 patients(21.1%) with acute coronary syndrome. Meanwhile, there were 10 patients(52.6%) with chronic atrial fibrillation versus 9 patients(47.4%) with new onset atrial fibrillation in the same group. Choose 20 inpatients also in our CCU room and in the year of 2006 who were diagnosed with CHD with sinus rhythm (SR) as a control group. Then compare the differences in the heart function(NYHA), the left atrial diameter, the end diastolic left ventricular diameter, and the coronary angiography between the two groups; RESULTS: The mean age, gender proportion and the prevalence of hypertension between the two groups are similar(P>0.05). The CHD with AF group had more severe heart failure than the control group(2.84±0.90 vs 2.30±0.65, P<0.05), and it also had a lower EF value than the control group(56.86±13.97% vs 60.71±5.78%, P<0.05). The CHD with AF group had a larger left atrial diameter than the control group(4.24±0.57cm vs 3.62±0.21cm, P<0.01). The differences in the end diastolic left ventricular diameter and the coronary angiography between the two groups were similar(P>0.05). The differences in the left atrial diameter and the coronary angiography between the two sub-groups(chronic atrial fibrillation versus new-onset atrial fibrillation) were similar(4.29±0.60cm vs 4.19±0.56cm, P>0.05); CONCLUSION: The left atrial enlargement is an important risk factor of CHD with AF. The patient of CHD with AF has more severe heart failure than the patient of CHD with SR. AF is not a risk factor of CHD, and it also has no relationship with the severity of the coronary artery atherosclerosis.
