Spine imaging diagnosis of burst fracture, relation result in senile degenerative cardiac valvular calcification and coronary heart disease in ultrasonic analysis of relationship between Dongguan City People's Hospital of Guangdong Province (523460), Chen Jianfu, Deng Bingshui, Hu Weiping. In our hospital from April 2007 to February 2009, we conducted a retrospective analysis on 392 cases of senile degenerative valvular disease. Among these, 178 cases were diagnosed with coronary heart disease. Analysis of the possible related factors, early intervention may reduce morbidity and mortality rates (a decrease in the incidence of coronary artery disease and myocardial infarction), reducing the risk of sudden cardiac death. With the development of ultrasonic technology, the detection rate of cardiac valvular calcification has gradually increased, and ultrasound heartbeat graph examination has shown its important value.
1. Data and Method
1.1 General Information: This group of 178 examples, all from our hospital outpatient and inpatient departments during the period from April 2007 to February 2009, had been diagnosed with coronary heart disease. There were 117 males and 61 female cases, with men having an average age of (71 ± 9) years; females' average age was (55 ± 6) years.
1.2 Method: Application of the United States HDI-4000 color Doppler diagnostic instrument, with a probe frequency of 2 ~ 4MHz. Routine cardiac ventricular septal defect observation, valve morphology and function, heart size, wall thickness, ejection fraction, E/A ratio were examined, excluding congenital heart disease and valvular disease patients. Specific observation of mitral annulus calcification of the aortic valve (AVC) number.
1.3 Diagnostic Criteria: Mitral annular calcification (MAC) and AVC, parasternal long-axis plane, apical four-chamber view, mitral valve and aortic valve short-axis view fully display valves after freeze image. Observation of the number and location of valvular calcification. Control group of male and female valves completely normal.
1.4 Statistics: Data ± S. Measurement data using t-test; count data by testing comparison between groups.
2. Results in Table 1 and 2.
Table 1 shows the incidence of calcified plaque coronary heart disease in different gender comparisons. Table 2 shows that for more than 3 calcified plaques, coronary heart disease had a significantly higher incidence than for 1~2 calcified plaques (P0.05). However, in MAC and AVC >3 calcification plaques, differences in coronary heart disease incidence were observed, but treatment differences were not statistically significant (P>0.05). Nevertheless, the two also have 3 or more calcified plaques with a high incidence of coronary heart disease up to 79.2%, showing a significant difference (P<0.01) compared to those with fewer plaques. Male incidence is higher than female.
Senile degenerative heart valvular disease can exist alone or coexist with other diseases, especially hypertension seen in 79 cases, where male and female patients with hypertension (79.9%), which may be due to elevated blood pressure, aortic valve subjected to mechanical stress increases, more likely to cause collagen fiber breakage forming gaps conducive to calcium salt deposition. MAC and AVC are among the most common calcium salt deposition sites in coronary heart disease. Some foreign researchers have confirmed that the aortic valve and MAC are part of systemic atherosclerosis, and coronary atherosclerosis is one of the manifestations of the heart. The results show that when mitral and aortic valves have 3 or more calcified plaques, there is a need for high attention to the presence of coronary artery disease, and early diagnosis and intervention treatment to improve prognosis. This paper reports results higher than other studies, possibly associated with regional differences. Ultrasonic heartbeat graph as a screening method has the advantages of simplicity, safety, good repeatability, and non-invasive features. MAC and AVC detection predict the presence and severity of coronary heart disease. In practical work, aged 60 patients can use MAC and AVC as preoperative screening indicators for coronary angiography to improve the early diagnosis rate of coronary heart disease and prevent cardiac events.
