The atherogenic index of plasma and its impact on recanalization of chronic total occlusion

Background: The plasma-derived atherogenic index (AIP) is associated with an increasing risk for cardiovascular diseases. Whether an increased AIP may predict the complexity of percutaneous coronary intervention (PCI) of chronic total occlusion (CTO), according to available research, has never been investigated before.Methods: Three hundred seventeen patients were included prospectively and treated with PCI for at least one CTO between 2012 and 2017. High-density lipoprotein cholesterol (HDL-C) and triglycerides (TG) plasma levels were measured 24 h before PCI. All patients were stratified into tertiles of AIP (defined as 0.11, 0.11–0.21, > 0.21) based on their TG/HDL-C (AIP) levels.Results: Mean AIP of all patients undergoing CTO-PCI was 0.53 ± 0.29. The majority of patients were male (82.6%), and mean age was 61 ± 10.4 years. Increased AIP > 0.21 was associated with longer occlusion length (statistical trend p = 0.082) and stent routes (p = 0.022) and with a higher number of implanted stents (n > 4) (statistical trend p = 0.072). Success rates were similar in all AIP categories (p = 0.461). In-hospital PCI-related complications were rare and not statistically different (p = 0.852).Conclusions: This study demonstrates for the first time that an increased AIP may predict the complexity of CTO-PCI and additionally may help to improve planning and quality of CTO-PCI

In-hospital outcome of re-attempted percutaneous coronary interventions for chronic total occlusion

Background: With the advent of novel recanalization techniques and emerging devices, percutaneous coronary intervention (PCI) has become a promising leading treatment option for patients with chronic total occlusions (CTO). The present study aims to evaluate the acute outcomes of PCI in previously failed re-attempted vs. first-attempted CTO-lesions. Methods: Between 2012 and 2019, 619 patients were included and treated with PCI of at least one CTO. 253 patients were re-attempted lesions, while 366 were initially attempted lesions. Results: Re-attempted lesions were more complex, including higher Japanese-CTO (J-CTO) score and the need for a retrograde approach. The procedure time and fluoroscopy time were longer in this group. Nevertheless, overall success rates were comparable between both groups of patients. In-hospital events were rare and without significant differences. Conclusions: Re-attempted CTO lesions are more complex than first-attempt lesions and are associated with longer procedural times. However, they can be safely intervened by experienced operators with a similar success rate

The GuideLiner catheter: A supportive tool in percutaneous coronary intervention of chronic total occlusion

Background: Failure of delivering a stent or a balloon across the target lesion during percutaneous coronary intervention (PCI) of chronic total occlusion (CTO), especially in arteries with calcified tortuous anatomy, is often due to insufficient backup support from the guiding catheter. The purpose of this study was to assess the feasibility of the GuideLiner (GL) catheter use. Methods: We examined 18 patients and used the GL catheter to overcome poor support and excessive friction in standardized antegrade and retrograde CTO procedures. The GL is a coaxial, monorail guiding catheter extension delivered through a standard guiding catheter and is available in different sizes. Results: Almost all lesions were classified as severely calcified (94.4 ± 0.24%). The Japanese CTO score reflecting lesion complexity was 3.56 ± 0.78. All procedures were performed femorally; the retrograde approach was used in 27.8 ± 0.46% of cases. The overall success rate was 88.9 ± 0.32%; there were no relevant complications. Conclusions: The GL catheter is an adjunctive interventional device which enhances and amplifies CTO-PCI. Its use is indicated in cases in which back-up force needs to be strengthened to pass a CTO despite advanced calcification. It can be recommended as an important additional tool in advanced interventional cardiology such as antegrade and retrograde CTO-PCI if other techniques like anchor balloon or anchor wire are not possible.

Prevalence and economic burden of pulmonary embolism in Germany

The prevalence of pulmonary embolism (PE), PE mortality and treatment-associated costs for the years 2000 to 2006 were analysed using a statutory health insurance sample of AOK Hesse/KV Hesse, which contained information for an 18.75% random sample of 1.9 million persons insured with the AOK Hesse. Within the sample a PE diagnosis was accepted as valid if it was documented as the main discharge diagnosis or as an additional hospital diagnosis during hospitalization and if at least one of the following criteria was met: prescription of oral anticoagulants or heparins, PE documented for at least two quarterly periods or documented in only one quarter for patients who died within 28 days after hospital discharge. The economic burden from the perspective of the insurance fund was assessed by an analysis of resource consumption (direct costs) and by a matched pair analysis with controls without PE to estimate excess costs. A 99% winsorization of each cost category was performed to control for extreme outlying values. The prevalence of PE as the main discharge diagnosis and an additional hospital diagnosis varied from 55.3 to 71.7 per 100,000 insurants in the years 2000 to 2006. Insurants aged 80 years and more had a prevalence of 406.9 per 100,000 (year 2006). From 2001 to 2003 the in-hospital mortality rate ranged from 20.4% to 24.9% and decreased to 14% in 2006. A total of 85% of all patients with PE who survived the first year had at least one prescription of vitamin K antagonists. For patients who survived the first year, treatment costs exceeded (sic) 20,000, with an estimation of additional costs of (sic) 5816 for men and (sic) 8962 for women in the matched-pair analysis. Owing to high in-hospital costs, the overall cost of treatment was highest for patients younger than 60 years. In conclusion, the prevalence rate of PE in Germany is comparable to international data. Treatment costs within the first year after hospital discharge are high, and there is a need to clarify the settings associated with PE in Germany with its high rate of prophylaxis

Impact of body mass index on acute outcome in percutaneous coronary intervention of chronic total occlusion

Background: Percutaneous coronary intervention (PCI) of total chronic total occlusion (CTO) still remains a major challenge in interventional cardiology. There is only insignificant knowledge reported in the literature about the influence of body mass index (BMI) on acute outcome, including success rates and complications in CTO-PCI. Methods: Between 2012 and 2017, we included 508 patients. They underwent PCI for at least one CTO. Antegrade and retrograde CTO techniques were applied. The retrograde approach was used only after failed antegrade intervention. BMI was calculated according to the definitions of the World Health Organization. It was subdivided as normal weight (18.5-24.9 kg/m(2)), overweight (25-29.9 kg/m(2)), obese (30-34.9 kg/m(2)), and very obese (>= 35 kg/m(2)). The Shapiro-Wilk test was used to test for normality of distribution. Continuous variables were tested for differences with Kruskal-Wallis or Mann-Whitney U test as appropriate. Categorical variables were tested with Fisher exact test. Results: Out of the 508 patients, 77 (15.2%) had normal weight, 286 (56.3%) were overweight, 106 (20.9%) obese, and 39 (7.7%) very obese. Radiation dose and examination time increased with elevated BMI categories (p < 0.001, p = 0.026). Success rates were similar in all BMI categories (p = 0.645). In-hospital procedural complications were rare and showed no statistically significant difference (p = 0.185). Conclusions: Our retrospective study suggests that there exists no significant association between overweight and acute outcome in patients undergoing CTO-PCI. It is safe and feasible to perform.

Trends in Atrial Fibrillation and Prescription of Oral Anticoagulants and Embolic Strokes in Germany

Background: The aim of the study was to compare trends in frequency of atrial fibrillation (AF) with the prescription rates of oral anticoagulants (OAC) and the incidence of embolic stroke (ES) from 2005 through 2014. Methods: Annual numbers of hospitalized patients with AF and ES were extracted from the Federal Bureau of Statistics. Defined daily doses (DDD) of prescribed OAC among outpatients were extracted from the insurance drug information system. Results: The number of cases hospitalized with the diagnosis AF increased continuously by 78.3% (1.25 Million in 2005 to 2.19 Million in 2014, p < 0.001), likewise frequency of ES increased by 89.0% (from 46,068 to 87,050, p < 0.001) and the number of prescribed DDD of OAC almost doubled by 105.4% (from 271,328 to 557,281, p < 0.001). There is an almost linear correlation between occurrence of AF and ES (R-2 = 0.9683). In contrast association between prescription rate of OAC and incidence of ES is not linear as there was a disproportional increase in OAC prescriptions beginning in the year 2010 that is not accompanied by a reduction of cases hospitalized with ES. Conclusions: Our analysis of drug treatment rates for OAC in outpatients and hospitalization rates for ES revealed a disproportional increase in prescription of OAC beginning in the year 2010 that does not affect the number of cases hospitalized with ES.
