Brief reportsEffect of glucose-insulin-potassium infusion on plasma free fatty acid concentrations in patients undergoing primary percutaneous coronary intervention for ST-elevation myocardial infarction

To determine the effect of glucose-insulin-potassium infusion on circulating levels of free fatty acids in the setting of contemporary management of ST-elevation myocardial infarction, we randomly assigned 20 patients who were undergoing primary angioplasty to glucose-insulin-potassium infusion or to standard care. Treatment with glucose-insulin-potassium was associated with significantly lower levels of free fatty acid after 24 hours compared with standard care.

Influence of metoprolol on heart rate variability in survivors of remote myocardial infarction

AbstractWe assessed the influence of metoprolol on heart rate variability in survivors of remote myocardial infarction. In 43 survivors of myocardial infarction 12 to 18 months previously (26 men and 17 women, aged 38 to 69 years), two 24-hour ambulatory electrocardiograms were recorded 2 weeks apart. In patients in group A (n = 28), who had taken metoprolol for the previous year, the drug was discontinued for 2 weeks, after which the first recording was done. The second recording was done 2 weeks after metoprolol was resumed. In patients in group B (n = 15), who had not taken metoprolol for the previous year, it continued to be withheld, and two 24-hour recordings were done 2 weeks apart. In group A, metoprolol increased the time domain variables indicative of enhanced vagal tone: root-mean-square successive difference in normal RR (NN) intervals was 20 ± 11 ms (mean ± SD) without and 24 ± 9 ms with metoprolol (p < 0.05), and the proportion of NN that differ by >50 ms (pNN50%) was 3.6 ± 6.0 without and 5.5 ± 6.0 with metoprolol (p < 0.05). In the frequency domain, the logarithms of the 24-hour very low frequency and the 24-hour high-frequency power (reflecting parasympathetic activity) were increased (5.12 ± 1.03 and 4.48 ± 1.51, respectively, without metoprolol; 5.32 ± 0.99 and 4.83 ± 1.24, respectively, with metoprolol, p < 0.05 for both). Thus, in survivors of remote myocardial infarction, metoprolol enhances parasympathetic cardiac activity in the time and frequency domain measures of heart rate variability.

Brief reportQuantitative assessment of coronary arterial diameter before and after balloon angioplasty of severe stenoses

In conclusion, when a coronary artery is severely narrowed and its distal portion filled by anterograde flow, the true luminal size of the distal vessel is often underestimated by the angiogram.
