“…No significant or very weak correlations between deceleration time of E velocity and LV filling pressure in the present study simply suggest that many patients with good LV function were included in this study [31], therefore, our results are consistent with previous reports [27][28][29][30][31]. Deceleration time of pulmonary venous flow was reported to be better than that of mitral flow in estimating LV filling pressure [32][33][34][35]. Difference between pulmonary venous and mitral A wave flow duration was also useful in predicting a large LV filling pressure rise at atrial systole [36].…”

Changes in collagen metabolism account for ventricular functional recovery following beta-blocker therapy in patients with chronic heart failure

While beta blockade improves left ventricular (LV) function in patients with chronic heart failure (CHF), the mechanisms are not well known. This study aimed to examine whether changes in myocardial collagen metabolism account for LV functional recovery following beta-blocker therapy in 62 CHF patients with reduced ejection fraction (EF). LV function was echocardiographically measured at baseline and 1, 6, and 12 months after bisoprolol therapy along with serum markers of collagen metabolism including C-terminal telopeptide of collagen type I (CITP) and matrix metalloproteinase (MMP)-2. Deceleration time of mitral early velocity (DcT) increased even in the early phase, but LVEF gradually improved throughout the study period. Heart rate (HR) was reduced from the early stage, and CITP gradually decreased. LVEF and DcT increased more so in patients with the larger decreases in CITP (r = -0.33, p < 0.05; r = -0.28, p < 0.05, respectively), and HR (r = -0.31, p < 0.05; r = -0.38, p < 0.05, respectively). In addition, there were greater decreases in CITP, MMP-2 and HR from baseline to 1, 6, or 12 months in patients with above-average improvement in LVEF than in those with below-average improvement in LVEF. Similar results were obtained in terms of DcT. There was no significant correlation between the changes in HR and CITP. In conclusion, improvement in LV systolic/diastolic function was greatest in patients with the larger inhibition of collagen degradation. Changes in myocardial collagen metabolism are closely related to LV functional recovery somewhat independently from HR reduction.

“…130 ms predicts a poor prognosis of restrictive diastolic dysfunction (12) and that a DCT of ! 100 ms indicates an increased pulmonary capillary wedge pressure (13). In our case, the DCT was 90 ms on the patient's last admission, whereas it had been > 150 ms on earlier admissions.…”

Unusual Case of Cardiac Amyloidosis Preceded by a Twenty-year History of Dilated Cardiomyopathy and Heart Failure

et al. 2016

Amyloidosis is a well-known but uncommon disease, and the physician must maintain a high index of suspicion in order to make a timely diagnosis. The expected survival of patients with cardiac amyloidosis is generally poor. In particular, survival has been reported to be 4-12 months for patients with amyloid light-chain amyloidosis with congestive heart failure. We herein report a rare case of cardiac amyloidosis in which the patient presented with cardiac hypertrophy after a 20-year history of dilated cardiomyopathy and heart failure.
