Journal of the American Heart Association 14(2) e034627 2025年1月21日BACKGROUND: The effect of worsening renal function and baseline chronic kidney disease (CKD) on outcomes in patients with chronic coronary syndrome in the setting of optimal medical therapy remains unknown. METHODS AND RESULTS: The REAL-CAD (Randomized Evaluation of Aggressive or Moderate Lipid Lowering Therapy With Pitavastatin in Coronary Artery Disease) study is a prospective, multicenter, randomized trial of high-dose (pitavastatin 4 mg/day) or low-dose (pitavastatin 1 mg/day) statin therapy in 12 118 patients with chronic coronary syndrome. The primary end point was a composite of cardiovascular death, nonfatal myocardial infarction, stroke, or unstable angina requiring hospitalization (major adverse cardiac and cerebral events [MACCE]). CKD was defined as an estimated glomerular filtration rate [eGFR] <60 mL/min per 1.73 m2. WRF was defined as a decrease in eGFR ≥20% in the initial year; borderline renal function was an annual decrease of 0%<eGFR<20%, and stable renal function was no decrease. Of 12 118 patients, 4340 had baseline CKD and 7778 did not. The rate of MACCE at 5 years was significantly lower in those without (5.5%) versus with CKD (9.5%) (P<0.0001). After excluding 1247 patients who had MACCE, were censored, or missing eGFR within 1 year, 10 871 patients were included. Of these, 3885 were baseline CKD and the remaining 6986 did not have baseline CKD. Of the 10 871 patients, 577 patients had WRF, 6014 patients showed borderline renal function, and the remaining 4280 patients maintained stable renal function. In patients with CKD, WRF was an independent predictor for MACCE at 4 years as compared with stable renal function (hazard ratio [HR]: 1.67; [95% CI, 1.03-2.73; P=0.039]). In patients without CKD, borderline renal function was a significant predictor for MACCE at 4 years compared with stable renal function (HR: 1.40 [95% CI, 1.03-1.91; P=0.032]). CONCLUSIONS: Baseline CKD was an independent predictor for MACCE in patients with CCS. WRF was a significant predictor for MACCE in patients with CKD. Because borderline renal function was an independent predictor for MACCE even in patients without CKD, mild-to-moderate annual declines of eGFR should be carefully monitored (NCT01042730).

Hypertension research : official journal of the Japanese Society of Hypertension 2024年9月19日The Japanese Society of Hypertension have established a blood pressure (BP) target of 130/80 mmHg for patients with coronary artery disease (CAD). We evaluated the data of 8793 CAD patients in the Clinical Deep Data Accumulation System database who underwent cardiac catheterization at six university hospitals and the National Cerebral and Cardiovascular Center (average age 70 ± 11 years, 78% male, 43% with acute coronary syndrome [ACS]). Patients were divided into two groups based on whether or not they achieved the guideline-recommended BP of <130/80 mmHg. We analyzed the relationship between BP classification and major adverse cardiac and cerebral event (MACCE) separately in two groups: those with ACS and those with chronic coronary syndrome (CCS). During an average follow-up period of 33 months, 710 MACCEs occurred. A BP below 130/80 mmHg was associated with fewer MACCEs in both the overall (hazard ratio [HR] 0.83, 95% confidence interval [CI] 0.70-1.00, p = 0.048) and the ACS group (HR 0.67, 95%CI 0.51-0.88, p = 0.003). In particular, stroke events were also lower among those with a BP below 130/80 mmHg in both the overall (HR 0.69, 95%CI 0.53-0.90, p = 0.006) and ACS groups (HR 0.44, 95%CI 0.30-0.67, p < 0.001). In conclusion, the achievement of BP guidelines was associated with improved outcomes in CAD patients, particularly in reducing stroke risk among those with ACS.

Japanese circulation journal 45(6) 661-6 1981年6月 査読有りThe relationship between myocardial infarct size and serum levels of cardiac myosin light chain II (LC II; 20000 daltons) was studied in 24 dogs with left anterior descending coronary artery occlusion. LC II in the serum was measured by the radioimmunoassay which we have recently developed. In our assay, 0.1--5.0 ng of LC II were effectively measurable. Serum LC II levels rose rapidly and stayed elevated long after coronary occlusion. Infarct size was determined by gross inspection. In 24 dogs, infarct size ranged from 0.3 to 41.7 per cent of left ventricular weight. LC II release was calculated by the formula of Shell and associates. Regression analysis showed good correlation between infarct size and LC II release (r = 0.78). Infarct size also correlated with maximal LC II level (r = 0.77), and LC II level 24 hours after coronary occlusion (r = 0.69). Detection of circulating LC II is a useful method since it can be applied to the diagnosis of acute myocardial infarction at the early as well as late stage and infarct size can be assessed by analysis of serum LC II levels.

Circulation research 45(4) 522-7 1979年10月 査読有りCardiac myosin obtained from atria had a higher Ca2+-activated ATPase activity than did cardiac myosin from ventricles in various species of animals and in humans. The increased specific activity of Ca2+-activated adenosine triphosphatase (ATPase) of atrial myosin appeared to correlate with the level of the activity of ventricular myosin ATPase in the animal, since the same order in ATPase activity, as observed in ventricular myosins from various animals, was noted in atrial myosins. The enzymatic properties of atrial myosin also were characterized by no activation by N-ethylmaleimide, low activating energy, and a lower rate of inactivation at alkaline pH compared with the same properties of ventricular myosin. These findings suggest a difference in the myosin molecule at or near the active site, involving some sulfhydryl groups, between the two types of cardiac myosin. The Mg2+-activated ATPase activity, both in the presence and absence of actin (which is thought to be closely related to the basic contraction mechanism), also was enhanced in atrial myosin. Thus, the ATPase activities of atrial and ventricular myosins were different with special reference to the reaction pathway involving calcium and magnesium ions and appear to account for the difference in the velocity of contraction between the atria and the ventricles.
