    Abstract The negative results of glucose-insulin-potassium (GIK) in the very large CREATE-ECLA trial that studied 20,201 patients with ST-elevation acute myocardial infarction (AMI), are disappointing and warrant thorough evaluation. We attempt to put the new data into perspective and uncover the serious flaws in the trial design, otherwise the whole metabolic concept will be disparaged. The crucial issue, developed from basic science data, is that GIK should be initiated very early, before, or at the time of reperfusion. Another problem with CREATE-ECLA is that the mortality in Killip class 1 reperfused patients was 7.1%, much higher than that of a recent Dutch study in which mortality was only 1.2%. Nonetheless, there was a strong trend towards a lower mortality in the sub-groups that received the best reperfusion therapy in CREATE-ECLA, as well as in the first of two rather small Dutch GIK trials. In the future, the ideal protocol to test would be if GIK were given in the ambulance as the patient is being transported to a specialized centre of percutaneous coronary intervention (PCI), with the aim of expanding the time window between pain onset and actual PCI.

    Abstract Increased diastolic chamber stiffness (upward arrow DCS) during ischemia may result from increased diastolic calcium, rigor, or reduced velocity of relaxation. We tested these potential mechanisms during severe ischemia in isolated red blood cell-perfused isovolumic rabbit hearts. Ischemia (coronary flow reduced 83%) reduced left ventricular (LV) contractility by 70%, which then remained stable. DCS progressively increased. When LV end-diastolic pressure had increased 5 mmHg, myofilament calcium responsiveness was altered with 50 mmol/l NH(4)Cl or 10 mmol/l butanedione monoxime. These affected contractility (i.e., a calcium-mediated force) but not upward arrow DCS. Second, quick length changes reversed upward arrow DCS, supporting a rigor mechanism. Third, ischemia increased the time constant of isovolumic pressure decline from 47 +/- 3 to 58 +/- 3 ms (P < 0.02) but concomitantly abbreviated the contraction-relaxation cycle, i.e., pressure dissipation occurred earlier without diastolic tetanization. Finally, to assess any link between rate of relaxation and upward arrow DCS, hearts were exposed to 10 mmol/l calcium. Calcium doubled contractility and accelerated relaxation velocity, but without affecting upward arrow DCS. Thus upward arrow DCS developed during ischemia despite severely reduced contractility via a rigor (and not calcium mediated) mechanism. Calcium resequestration capacity was preserved, and reduced relaxation velocity was not linked to upward arrow DCS.

    Abstract Objective: Female gender is associated with reduced tolerance against acute ischemic events and a higher degree of left ventricular hypertrophy under chronic pressure overload. We tested whether female and male rats with left ventricular hypertrophy present the same susceptibility to demand ischemia.
    Methods: Hearts from hypertrophied female and male salt-resistant and salt-sensitive Dahl rats (n=8 per group) underwent 30min of demand ischemia induced by rapid pacing (7Hz) and an 85% reduction of basal coronary blood flow, followed by 30min of reperfusion on an isovolumic red cell perfused Langendorff model.
    Results: In female hearts, high-salt diet induced a pronounced hypertrophy of the septum (2.38+/-0.09 vs 2.17+/-0.08mm; p<0.01), whereas male hearts showed the greatest increase in the anterior/posterior wall of the left ventricle (LV) (3.19+/-0.22 vs 2.01+/-0.16mm; p<0.05) compared with salt-resistant controls. At baseline, LV-developed pressure/g LV was significantly higher in female than male hearts (200+/-13 and 196+/-14 vs 161+/-10 and 152+/-15mmHgg(-1); p<0.01), independent of hypertrophy, indicating greater contractility in females. During ischemia, LV-developed pressure decreased in all groups; at the end of reperfusion, hypertrophied female and male hearts showed higher developed pressures independent of gender (148+/-3 and 130+/-8 vs 100+/-7 and 85+/-6mmHg; p<0.01). In contrast, diastolic pressure was more pronounced in female than in male hypertrophied hearts during ischemia and reperfusion (24+/-3 vs 12+/-2mmHg; p<0.01).
    Conclusions: In the pressure overload model of the Dahl salt-sensitive rat, female gender is associated with a more pronounced concentric hypertrophy, whereas male hearts develop a more eccentric type of remodeling. Although present at baseline, after ischemia/reperfusion systolic function is gender-independent but more determined by hypertrophy. In contrast, diastolic function is gender-dependent and aggravated by hypertrophy, leading to pronounced diastolic dysfunction. We can conclude that in the malignant setting of demand ischemia/reperfusion gender differences in hypertrophied hearts are unmasked: female hypertrophied hearts are more susceptible to ischemia/reperfusion than males. To determine whether in female hypertensive patients with acute coronary syndromes, diastolic dysfunction could contribute to the worse clinical course, further experimental and clinical studies are needed.

    Abstract The goal of this study was to determine how short-term (12 weeks) angiotensin type I (AT1) block begun late in life affects aspects of myocardial biology and physiologic function altered by normal aging. Exercise capacity, myocardial morphology, histopathology, and coronary vascular function (degree of coronary vasodilation in response to adenosine) were evaluated in 53 Fischer 344 rats. Adult (6 months of age) and old (21 months of age) rats were studied after 12 weeks of either control drinking water, a low dose of candesartan that did not significantly lower blood pressure (1 mg/kg/d), or a high dose of candesartan (10 mg/kg/d). Significant age-associated changes in exercise capacity (38% decrease), coronary dilation in response to adenosine (41% decrease), and histopathology occurred but were not affected by candesartan treatment. Age-associated myocardial hypertrophy occurred as indicated by an increase in heart weight-to-tibia length ratio from 0.27 g/cm +/- 0.01 in the adult controls to 0.34 g/cm +/- 0.02 in the old controls (P < 0.05). This hypertrophy in the aged hearts was significantly attenuated by both low-dose (0.30 g/cm +/- 0.01) and high-dose (0.29 g/cm +/- 0.01) candesartan (P < 0.05). Echocardiographic measurements indicate that the candesartan-induced decrease in hypertrophy occurred concomitantly with slight decreases in septal wall thickness and left ventricular (LV) chamber diameter. It is concluded that short-term AT1 block, even when initiated late in life, can decrease age-associated LV hypertrophy independent of blood pressure-lowering effects.

    Abstract Background: This study sought to determine whether tight glycemic control with a modified glucose-insulin-potassium (GIK) solution in diabetic coronary artery bypass graft (CABG) patients would improve perioperative outcomes.
    Methods and results: One hundred forty-one diabetic patients undergoing CABG were prospectively randomized to tight glycemic control (serum glucose, 125 to 200 mg/dL) with GIK or standard therapy (serum glucose <250 mg/dL) using intermittent subcutaneous insulin beginning before anesthesia and continuing for 12 hours after surgery. GIK patients had lower serum glucose levels (138+/-4 versus 260+/-6 mg/dL; P<0.0001), a lower incidence of atrial fibrillation (16.6% versus 42%; P=0.0017), and a shorter postoperative length of stay (6.5+/-0.1 versus 9.2+/-0.3 days; P=0.003). GIK patients also showed a survival advantage over the initial 2 years after surgery (P=0.04) and decreased episodes of recurrent ischemia (5% versus 19%; P=0.01) and developed fewer recurrent wound infections (1% versus 10%, P=0.03).
    Conclusions: Tight glycemic control with GIK in diabetic CABG patients improves perioperative outcomes, enhances survival, and decreases the incidence of ischemic events and wound complications.
