The Impact

The purpose of this study is to analyse the disparities in the distribution of percutaneous coronary intervention (PCI) centres in Poland and the impact of eventual inequities on access to the invasive treatment of acute myocardial infarctions (AMI). To examine the distribution of PCI centres against population size and geographic size in Poland, the Gini coefficient calculated based on the Lorenz Curve was engaged. In addition, the regression function was employed to estimate the impact of distribution of PCI centres on access to invasive procedures (coronarographies and primary percutaneous coronary intervention). Data were collected from the public statistical system and Polish National Health Fund database for the year 2018. The relation and the level of equity was measured based on the aggregated data at a district (voivodeship) level. The results of the Gini coefficient analysis show that the distribution of invasive cardiology units measured against population size is more equitable than when measured against geographic size. In addition, the regression analysis shows the moderate size of the positive correlation between number of PCI centres per 100,000 population and the number of all categories of the invasive treatment of AMI per 100,000 population, and the lack of similar correlation in case of the number of PCI centres expressed per 1000 km2, which could be evidence of an insufficiency of PCI centres in areas where the concentration of PCI centres per 100,000 population is lower. The main implication for policy makers that results from this research is the need for a correction of PCI centres distribution per 100,000 inhabitants to ensure better access to invasive procedures.

The Impact

Coronary artery disease in patients with diabetes is frequently a diffuse process with multivessel involvement and is associated with increased risk for myocardial infarction and death. The role of percutaneous coronary intervention (PCI) versus coronary artery bypass grafting (CABG) in patients with diabetes and multivessel disease who require revascularisation has been debated and remains uncertain. The debate has been continued mainly because of the question to what degree an increased risk for in-stent restenosis among patients with diabetes contributes to other late adverse outcomes. This article reviews outcomes from early trials of balloon angioplasty versus CABG through later trials of bare-metal stents versus CABG and more recent data with drug-eluting stents as the comparator. Although not all studies have been powered to show statistical significance, the results have been generally consistent with a mortality benefit for CABG versus PCI, despite differential risks for restenosis with the various PCI approaches. The review also considers the impact of mammary artery grafting of the left anterior descending artery and individual case selection on these results, and proposes an algorithm for selection of patients in whom PCI remains a reasonable strategy.

Abstract Background Females comprise a minority of patients with chronic total occlusions (CTO). It is known that men have a greater benefit from CTO percutaneous coronary intervention (PCI) than women. We aimed to determine gender-based differences in baseline characteristics and outcomes after PCI in patients with CTO. Methods The Netherlands Heart Registration (NHR) is a nationwide registry that registers outcomes of cardiac interventions. For the purpose of this analysis, the data of all patients undergoing PCI from inception of the NHR to December 2018 were selected, that included PCI with at least one CTO in one of the treated coronary arteries. We compared baseline characteristics and the outcomes 1 year mortality, 30 day myocardial infarction (MI) and target vessel revascularization (TVR) <1 year between men and women. Results A total of 7560 patients were identified that underwent PCI between January 1, 2015 and December 31, 2018 with at least 1 CTO in the treated vessel. A total of 5850 was male (77.4%) and 1710 was female (22.6%). Women were older (68.5±10.6 versus 64.7±10.6 years old, p<0.001), and more frequently had diabetes (29.4% [n=529] versus 25.0% [n=1602], p<0.001) and kidney disease (4.5% [n=529] versus 2.2% [n=142], p<0.001). However, men had more extensive cardiovascular disease, i.e. multi-vessel disease (56.0% [n=3584] versus 50.4% [n=912], p<0.001), previous MI (39.7% [n=2527] versus 31.0% [n=555], p<0.001), previous PCI (48.2% [n=1967] versus 40.2% [n=455], p<0.001) and previous coronary artery bypass grafting (16.8% [n=1085] versus 10.5% [n=191], p<0.001) and more frequently presented with an out-of-hospital cardiac arrest, compared to women (2.1% [n=136] versus 1.1% [n=20], p=0.004). The 1-year mortality was higher in women (10.3% versus 7.5%, p<0.001), as well as the 30-day MI (0.9% versus 0.4%, p=0.043), but men had higher risk for TVR<1 year (11.7% versus 9.5%, p=0.044). Corrected for age and comorbidities, female gender was an independent predictor for mortality (Figure 1; odds ratio 1.83, 95% confidence interval 1.08–3.11, p=0.025). Conclusion In this nationwide registry comprising 7560 CTO patients undergoing PCI, significant gender-based differences were found. Males were found to have more extensive cardiovascular disease. However, females were at higher risk of mortality, possibly due to higher age and higher prevalence of concomitant comorbidities. Figure 1.

The Impact

Background: Thiazolidinediones (TZD) have been shown to decrease intimal hyperplasia by intravascular ultrasound after coronary stenting. However, a recent meta-analysis showed increased MI and suggested increased CV deaths with TZD use. We examined the impact of TZD use on the 1-year clinical outcomes of diabetic patients undergoing percutaneous coronary interventions. Methods: From 2000 through 2003, 598 diabetic patients underwent percutaneous coronary intervention at Emory University. Medication profiles were available for all patients who were divided into two groups: those that had a TZD as part of their diabetes regimen and those that did not. We compared the baseline clinical characteristics, angiographic characteristics, and 1 year rate of a composite endpoint of death, myocardial infarction, and revascularization between the two groups. Results: There was no difference between the two groups with regards to age, sex, baseline medical conditions, medication regimens, and overall glycemic control at the time of percutaneous coronary intervention. The lesions in both groups were of similar length, diameter, and characteristics. At 1 year the composite of death, non-fatal myocardial infarction (MI), and revascularization was not statistically different in the diabetics taking TZDs compared to those not taking TZDs (28.5% vs. 23.2%, p=0.15). There were also no differences in the rates of death and non-fatal MI. There was however a statistically significant increase in the rate of revascularization in diabetics taking TZDs compared to those not taking TZDs (25.4% vs. 17.3%, p=0.02). Conclusion: Diabetic patients undergoing coronary stenting who were on TZDs had a statistically significant increased rate of revascularization. However, there was a similar rate of the combined endpoint of death, non-fatal MI, and revascularization in all diabetic patients irrespective of TZD usages.
