Therefore, in this study, using the exercise QRS score, we sought to determine if slow coronary flow (SCF) phenomenon is associated with the exercise-induced myocardial ischemia. This retrospective study included 23 patients evaluated for suspected coronary artery disease and found to have SCF (group I) and 19 subjects with angiographically-defined significant coronary artery stenosis (group II). All study subjects underwent treadmill exercise testing using the modified Bruce protocol. For each subject the amplitude of the Q, R, and S waves in leads aVF and V5 was measured manually using calipers before and immediately after exercise. The QRS score was calculated by subtracting the Q, R, and S wave differences in leads aVF and V5. There was no difference between the two groups with respect to demographic properties. The peak heart rate achieved, baseline and peak systolic-diastolic blood pressure, exercise duration, and the metabolic equivalent values were similar in both groups. The maximum ST-segment depression ratio was significantly lower in patients with SCF than those of significant coronary stenosis (0.8 +/- 0.4 vs 1.3 +/- 0.5 P = 0.001, respectively). However, the exercise QRS score was found to be similar in both groups (3.3 +/- 2.3 vs 2.1 +/- 3.0 P = 0.2, respectively). The data suggest that SCF phenomenon may alone lead to myocardial ischemia even in the absence of obstructed major epicardial coronary arteries as detected by similar exercise QRS scores to those of significant coronary artery stenosis.","PeriodicalId":14717,"journal":{"name":"Japanese heart journal","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2004-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1536/jhj.45.419","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"24603496","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We studied 129 MI patients not given reperfusion therapy who underwent coronary angiography in the chronic stage.

However, the mechanism of the LV dysfunction is totally unknown. It has been suggested that overproduction of nitric oxide induced by inflammatory cytokines may contribute to the LV dysfunction in some diseased states. In this study, we examined whether inflammatory cytokines play a role in the altered LV function in HD patients. The plasma concentrations of 5 major inflammatory cytokines, including interleukin (IL)-1alpha, IL-1beta, IL-6, tumor necrosis factor-alpha, and macrophage-colony stimulating factor (M-CSF) were measured by enzyme immunoassay with horseradish peroxidase in 18 consecutive patients on HD and in 16 control subjects. Then, we examined the relationship between plasma concentrations of M-CSF and LV ejection fraction (EF) on echocardiography. Among the inflammatory cytokines examined, only the plasma concentrations of M-CSF were significantly elevated in patients on HD as compared to the control subjects. There was no significant change in the M-CSF concentrations before and after HD. Furthermore, there was a significant negative correlation between the plasma concentrations of M-CSF and LVEF. These results suggest that elevated levels of plasma M-CSF may exist prior to the development of LV dysfunction observed in HD patients.","PeriodicalId":14717,"journal":{"name":"Japanese heart journal","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2004-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"24603472","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These indices, however, refer to cases of normal hearts, and there are no reports studying these indices following acute myocardial infarction. In this study, we investigated whether FPSI and Pzf truly measure the extent of myocardial salvage after successful reperfusion therapy. We also developed a new index of zero pressure flow, Fzp. Nineteen patients who underwent successful reperfusion therapy to the proximal portion of the left anterior descending artery (LAD) were studied. After successful reperfusion therapy, a Doppler wire was placed into the LAD. Aortic pressure was recorded in real time. Results from the aortic pressure and flow meter were combined to produce FPSI, Pzf, and Fzp. All cases underwent a resting thallium (Tl) and BMIPP scintigram within five days of successful reperfusion therapy. Infarcted myocardium was estimated using a severity score calculated from the Tl scintigraphy (TlSS), and the BMIPP (BMIPPSS) was estimated using a severity score. Patients with a TlSS/BMIPPSS ratio of less than 0.4 were assigned to the successful salvage group (group S), while the others were assigned to the failed salvage group (group F). FPSI of group F was 1.91 +/- 0.26 m/sec and of group S was 0.92 +/- 0.43 m/sec (P < 0.01). Pzf of group F was 51 +/- 3 mmHg and of group S was 51 +/- 5 mmHg (NS). Fzp of group F was -98 +/- 16 cm/sec and of group S was -46 +/- 4 cm/sec (P < 0.05). FPSI and the new index of Fzp were useful in estimating the extent of myocardial salvage.
