Strategic Accessibility Competition
No full textWe analyze the effect of competition in market-accessibility enhancement among quality-differentiated firms. Firms are located in regions with different ex-ante transport costs to reach the final market. We characterize the equilibrium of the two-stage game in which firms first invest to improve market accessibility and then compete in prices. Efforts in accessibility improvement crucially depend on the interplay between the willingness to pay for the quality premium of the median consumer and the ex-ante difference in accessibility between regions. From the social standpoint, all the accessibility investment should be carried out by the high-quality firm. Finally quality choice is endogenized.
Contrast-enhanced cardiovascular magnetic resonance in primary and ischemicdilated cardiomyopathy.
No full textObjectives Differentiation between primary dilated cardiomyopathy and ischemic cardiomyopathy has an important clinical significance. Contrast-enhanced cardiovascular magnetic resonance can play a role in this task, identifying myocardial scarring or fibrosis as presence of delayed enhancement. The aim of the present study was to evaluate the diagnostic potential of contrast-enhanced cardiovascular magnetic resonance in differentiating dilated cardiomyopathy from ischemic cardiomyopathy.
Methods Contrast-enhanced cardiovascular magnetic resonance was performed in 100 patients with left ventricular dilatation and reduced systolic function: 24 had normal coronary arteries (dilated cardiomyopathy group) and 76 had significant coronary artery disease (ischemic cardiomyopathy group), with or without previous myocardial infarction.
Results In the dilated cardiomyopathy group, only seven (29%) patients showed delayed enhancement and its pattern was characterized by mid-wall, patchy or diffuse location. All patients with ischemic cardiomyopathy and prior myocardial infarction (54 subjects) showed delayed enhancement with subendocardial (n=4) or transmural (n=50) extension. Among the 22 patients with ischemic cardiomyopathy but without previous myocardial infarction, 13 (59%) showed either subendocardial (n=4) or transmural (n=9) delayed enhancement. Conclusions Patterns of delayed enhancement are different in dilated cardiomyopathy and ischemic cardiomyopathy, reflecting the presence of scarring or various degrees of fibrosis in left ventricular myocardium. The presence of subendocardial or transmural delayed enhancement at contrast-enhanced cardiovascular magnetic resonance allowed distinction between dilated cardiomyopathy and ischemic cardiomyopathy with high sensitivity (88%) and specificity (100%). Integration of cardiovascular magnetic resonance results with angiographic information can be useful in the identification of pathogenic mechanisms underlying left ventricular dysfunction
Length of ischemia is a major determinant of microvascular obstruction. A study performed with contrast enhanced magnetic resonance after primary angioplasty
No full textDuration of ischemia is a major determinant of transmurality and microvascular obstruction assessed by magnetic resonance after primary angioplasty
No full textOBJECTIVES:
This study sought to assess the relationship between duration of ischemia and both myocardial transmural necrosis (TN) and severe microvascular obstruction (SMO), by contrast-enhanced magnetic resonance (CE-MR), in patients with acute myocardial infarction (AMI) treated with angioplasty (PCI), and to estimate the risk of TN and SMO with the duration of ischemia.
BACKGROUND:
The impact of ischemic time on myocardial and microvascular injury is not well characterized in people.
METHODS:
We performed CE-MR in 77 patients with first AMI, 5 +/- 3 days after successful PCI. The AMI was labeled as transmural if hyperenhancement at CE-MR was extended to > or =75% of the thickness in two or more ventricular segments. The SMO was identified as areas of late hypoenhancement surrounded by hyperenhanced tissue. The relationship between ischemic time and CE-MR evidence of SMO or TN was evaluated by logistic regression.
RESULTS:
Thirteen patients were excluded because of preprocedural Thrombolysis In Myocardial Infarction (TIMI) flow grade 3 of the infarct-related artery. For the remaining 64 patients, the mean time to treatment was 190 +/- 110 min, 45 (65%) patients had TN and 23 (39%) had SMO. Mean pain to balloon time was 90 +/- 40 min, 110 +/- 107 min, and 137 +/- 97 min in patients without TN and SMO, with TN but without SMO, or with both TN and SMO, respectively (p = 0.001). Multivariate analysis showed that time delay was significantly associated both with TN (odds ratio per 30 min, 1.37, p = 0.032), and SMO (odds ratio per 30 min, 1.21; p = 0.021).
CONCLUSIONS:
In AMI patients with impaired coronary perfusion undergoing PCI, the risk of TN and SMO increases with the duration of the ischemic time
