BACKGROUND: Whereas electrical, structural, and contractile remodeling processes are well-recognized contributors to the self-perpetuating nature of AF, the impact of cardiac metabolism upon the persistence/initiation of this resilient arrhythmia has not been explored in detail.

It was suggested that aging did not only influence diastolic filling period, but also influence STI. 3. With increasing age, whether at rest or during exercice, fractional shortening of minor semiaxis, mean velocity of circumferential fiber shortening, cardiac index and ejection fraction did not change, but immediately post pacing, PEP prolonged and PEP/ LVET increased in elderly group and did not change in young group. It was suggested that STI was sensitivity in detecting systolic function of LV. 4. There was a good correlation between aging and decreased compliance and diastolic function of left ventricle which was manifested by a reduction of early diastolic peak folw velocity, time-velocity integral of early diastole, 1/3 filling fraction (1/3FF)(r=-0.958,-0.875 and -0.937, P＜0.01～0.001) and a significant compansatory increase in peak flow velocity of atrial contraction, time-velocity integral of atrial contraction, the ratio between APFV and EPFV and the ratio of ATVI and Total TVI (r=0.958, 0.956, 0.966 and 0.986, P＜0.001) and the prolongation of Dec T and RFP with increasing age. It was particularly true for the subgroups above the age of 50 years.

静息状态下收缩时间间期与年龄无相关性，负荷后即刻，老年组射血前期延长(P＜0.05)，射血前期与射血期比值加大(P＜0.05)，青年组无变化，提示年龄因素亦影响STI，但由于静息状态下得到代偿，STI变化往往表现不明显。3、静息及负荷状态左室短轴缩短率、平均周径缩短率、心指数及射血分数均不随年龄增长而变化，而负荷后即刻老年组PEF延长，PEP/LVET加大，提示STI是检测左室收缩功能的敏感指标。4、随年龄增长，心房收缩期充盈峰值流速、流速积分、充盈分数及心房收缩期与舒张早期充盈峰值流速之比值显著增高(r＝0.958、0.956、0.986及0.966，P均＜0.001)，舒张早期充盈峰值流速及流速积分、1/3充盈分数(1/3FF)下降(r＝-0.958、-0.875及-0.937，P＜0.01～0.001)。

S.From all the patients with MB-MCA and whose MCA were encased by the myocardium completely,30 patients were choosed randomly,their datasets were reconstructed seriatim by every 5%R-R interval,the whole cardiac cycle were reconstructed by 20 phases,the diameter of the mural coronary arteries of every phase was reviewed and measured,the phases were found out where the diameters were maximal and minimal,the systolic compression rate was calculated,Pearson correlation analysis was used to analyze the relation between length,depth,and degree of systolic compression of the mural coronary artery.

s表示。在所有存在MB-MCA并且MCA被心肌完全包饶的病例图像中，随机抽取30例图像的数据，以每隔5%R-R间期为一个重建时相，对每个病例0.100%整个心动周期分20个期相进行重建，观察并测量MCA在整个心动周期中管径的变化，探索管径最大和最小时的时相显示规律，计算MCA最大狭窄程度，应用Pearson相关统计分析MCA狭窄程度与MB的长度及厚度之间的相关关系。
