BENEFICIAL EFFECT OF RECRUITABLE COLLATERALS: A 10-YEAR FOLLOW-UP STUDY IN PATIENTS WITH STABLE CORONARY ARTERY DISEASE UNDERGOING QUANTITATIVE COLLATERAL MEASUREMENTS, by Meier et al.
|
|---|
In this study, 845 individuals (age 62±11 years), including
106 patients without coronary artery disease (CAD) and 739 patients
with chronic stable CAD, underwent a total of 1053 quantitative,
coronary pressure–derived collateral measurements between
March 1996 and April 2006. All of the patients were prospectively
included in a collateral flow index (CFI) database that contained
information on recruitable collateral flow parameters obtained
during a 1-minute coronary balloon occlusion, and they were
divided into 2 groups: those with CFI <0.25 and those with
CFI
0.25. Cumulative 10-year survival rates in relation to all-cause
deaths and cardiac deaths were 71% and 88% in patients with
low CFI, respectively, and 89% and 97% in the group with high
CFI (
P=0.0395 and
P=0.0109). These results indicate a correlation
between a CFI >0.25 and a reduced rate of cardiac deaths
and acute myocardial infarction in patients with chronic stable
CAD. See p
975.

FLUORESCENT CARDIAC IMAGING: A NOVEL INTRAOPERATIVE METHOD FOR QUANTITATIVE ASSESSMENT OF MYOCARDIAL PERFUSION DURING GRADED CORONARY ARTERY STENOSIS, by Detter et al.
|
|---|
Increased use of surgical revascularization for symptomatic
coronary artery disease has resulted in a number of technical
advances and alternative coronary artery bypass grafting techniques.
Key to the success of these procedures is the establishment
and long-term maintenance of graft patency. Prior studies have
revealed that a large proportion of graft failures occur early
as a result of technical issues, which suggests that the methodology
to assess intraoperative bypass graft function is warranted.
To date, a number of techniques have been used, including thermal
coronary angiography, ultrasound transit-time flow measurement,
and high-frequency epicardial echocardiography; however, each
of these methods has limitations. In this issue of
Circulation,
Detter et al describe the use of a novel indocyanine green-based
near-infrared fluorescence imaging system in the setting of
graded coronary artery stenosis to examine myocardial blood
flow. Here, they provide evidence that myocardial blood flow
may serve as an indirect parameter to detect early graft anastomotic
failure. See p
1007.

IMPACT OF REPEATED DIETARY COUNSELING BETWEEN INFANCY AND 14 YEARS OF AGE ON DIETARY INTAKES AND SERUM LIPIDS AND LIPOPROTEINS: THE STRIP STUDY, by Niinikoski et al.
|
|---|
Autopsy and epidemiological studies have shown that atherosclerosis
begins in childhood. In a randomized, prospective trial (the
Special Turku Coronary Risk Factor Intervention Project [STRIP]),
infants had been assigned at age 7 months to either a low-saturated-fat,
low-cholesterol diet or a control diet. Niinikoski and colleagues
now report the effects of serial dietary counseling on lipid
values, growth, and development at age 14 years. The intervention
group had lower serum total and low-density lipoprotein cholesterol
levels, but high-density lipoprotein cholesterol levels were
similar. The study groups had similar growth rate, body mass
index, and pubertal development. These data show that repeated
counseling for a low–saturated-fat, low-cholesterol diet
favorably affects lipid profile throughout the first 14 years
of life and that saturated fat restriction does not influence
growth or timing of puberty in healthy children. See p
1032.
