The Current State of Left Main Percutaneous Coronary Intervention

AbstractPurpose of ReviewWhile coronary artery bypass grafting (CABG) remains the standard of care, advances in stenting technology and procedural technique are changing the role of percutaneous coronary intervention (PCI) in the treatment of severe left main coronary artery (LMCA) disease. We review contemporary evidence comparing PCI and CABG for the treatment of severe LMCA disease, discuss optimal techniques during left main PCI, and provide guidance on studied revascularization strategies within specific patient subgroups.Recent FindingsResults from randomized control trials of patients treated with PCI or CABG for severe LMCA disease demonstrate comparable short- and mid-term rates of death, myocardial infarction (MI), and stroke, but increased rates of repeat or target-vessel revascularization after PCI. Though extended follow-up data has suggested lower long-term rates of MI and stroke in patients with severe LMCA disease treated with CABG, results from patients undergoing PCI with second-generation drug-eluting stents (DES) demonstrate non-inferiority in these outcomes. These findings are generalizable to patients with severe LMCA disease having low to intermediate anatomic complexity. Intravascular ultrasound and double kissing (DK) crush stenting also reduce adverse event rates among patients undergoing left main PCI and improve long-term outcomes.SummaryIn patients with severe LMCA disease having low to intermediate anatomic complexity, both CABG and PCI with seco...

AbstractWe investigated the relationship between time trends in nutrient intake and coronary risk factors/mortality rates in Tanushimaru, a Japanese cohort of the Seven Countries Study. All men between the ages of 40 and 64 were enrolled. Subjects numbered 628 in 1958, 539 in 1977, 602 in 1982, 752 in 1989, 402 in 1999, 329 in 2009, and 160 in 2018. Eating patterns were evaluated by 24-h dietary recall from 1958 through 1989, and by a food frequency questionnaire administered from 1999 through 2018. The total daily energy intake decreased from 2,837  kcal in 1958 to 2,096 kcal in 2018. Carbohydrate intake as a pe...

CONCLUSION: As reimbursement for emergency medicine in Germany was recently rearranged, quality benchmarking has gained incremental importance. Mandatory joint quality measurement in both concepts ensuring gap analysis and process improvement is encouraged. PMID: 31970463 [PubMed - as supplied by publisher]

Authors: Goeder D, Oberhoffer R Abstract Cardiovascular diseases are among the leading causes of death worldwide. Apart from a few exceptions heart attack, stroke and peripheral arterial occlusive disease first occur in later adulthood. The cornerstone for these diseases, however, is already laid by accelerated vascular aging in childhood. Apart from pediatric medical preventive check-ups, the medical care of the parents should also be a reason for taking action. A detailed family history enables many conclusions to be drawn about the cardiovascular risk of the next generation This requires targeted diagn...

ConclusionAbout two third of the patients had poor treatment outcome. Educational status and mean length of hospital stays were independent predictors of poor treatment out-comes. An emergency care setup capable of early patient evaluation, identification and management of stroke complications is crucial to overcome early stroke related mortality.

Authors: Taguchi A, Sakamoto S, Okazaki T, Oshita J, Kuwabara M, Kurisu K Abstract BACKGROUND: Several recent randomized controlled trials have reported that perioperative complications of carotid artery stenting increase with age, and Japan has the highest proportion of elderly in the world. We retrospectively compared clinical factors, treatment outcomes, and adverse events between younger and elderly carotid artery stenting patients at a single institution in Japan to assess carotid artery stenting safety for the aged population. METHODS: A total of 150 consecutive patients treated with carotid artery stenti...

AbstractPlatelet microvesicles (PMV) have previously been found elevated in acute ischemic stroke (IS) and could be biomarkers for risk of recurrence. PMV surface antigens such as P-selectin and phosphatidylserine (PS) reflect platelet activation and procoagulance. Tissue factor-positive microvesicles (TF+MV) are considered procoagulant, in particular if co-expressing PS. We enumerated MV subpopulations with these surface antigens in a cohort of 211 patients with primarily non-cardioembolic IS or transient ischemic attack (TIA) and investigated their association with long-term outcome. MV concentrations were determined by ...

Conclusions: Mildly abnormal baseline lipid levels were associated with an increased future risk of ASCVD events, particularly MI, whereas measures of lipid variability were not. Therefore, in young adults, achieving optimal lipid levels could be valuable in the prevention of ASCVD. PMID: 31978313 [PubMed - as supplied by publisher]
