Are Hospitalizations for Percutaneous Coronary Procedures Missed Opportunities for Teaching Rules of Secondary Prevention?

Background and aims: Percutaneous coronary intervention (PCI) is the most frequently used revascularization approach, often repeatedly applied. The quest for the ultimate revascularization procedure however may capture cardiologist’s attention and lead them to minimize the issue of secondary prevention in their patients. Aims of this study were to assess: 1. The individual risk factor profile, 2. The relation between the risk factors correction and the number of hospital admissions for elective procedures, 3. The appropriateness of medical treatment in patients admitted for elective coronary invasive procedures (diagnostic and interventional). 4. The patients knowledge of threshold values for cardiovascular risk factors. Patients and Methods: 100 patients (71% males, mean age 68 years) consecutively admitted for elective coronary angiography or PCI. They underwent a classical risk factors assessment and were divided in three groups according to the number of admissions for coronary angiography and in two groups according to the number of PCIs. Results: Fifty-seven % of patients had been previously admitted for invasive examination at least three times and 58% had already been treated with at least one PCI. Seventyone % were treated with beta-blockers but only 25% of them received a dosage found effective in RCTs (randomized clinical trials). Sixty % were treated with ACE-inhibitors and 83% received the dosage found effective in RCTs. Fifty-two % were treated with statins and 95% received a dosage found effective in RCTs. Nine % were still active smokers. Fourtynine % had a LDL cholesterol level above 100 mg/dL. The percentage of patients not on target was unrelated to the number of hospital admissions for invasive procedures. Conclusions: Modern cardiology is quickly embracing high tech procedures and trials results but often fails to spend enough time teaching how to control risk factors according to the recommendations of the evidence-based guidelines, even independently of the number of hospitalizations for invasive cardiovascular procedures

GARFIELD-AF risk score for mortality, stroke and bleeding within 2 years in patients with atrial fibrillation.

AIMS: To determine whether the GARFIELD-AF integrated risk tool predicts mortality, non-haemorrhagic stroke/systemic embolism (SE), and major bleeding for up to two years after new onset AF and to assess how this risk tool performs compared with CHA2DS2-VASc and HAS-BLED. METHODS AND RESULTS: Potential predictors of events included demographic and clinical characteristics, choice of treatment, and lifestyle factors. A Cox proportional hazards model was identified for each outcome by least absolute shrinkage and selection operator (LASSO) methods. Indices were evaluated in comparison with CHA2DS2-VASc and HAS-BLED risk predictors. Models were validated internally and externally in ORBIT-AF and Danish nationwide registries. Among the 52,080 patients enrolled in GARFIELD-AF, 52,032 had follow-up data. The GARFIELD-AF risk tool outperformed CHA2DS2-VASc for all-cause mortality in all cohorts. The GARFIELD-AF risk score was superior to CHA2DS2-VASc for non-haemorrhagic stroke, and it outperformed HAS-BLED for major bleeding in internal validation and in Danish AF cohort. In very low to low risk patients (CHA2DS2-VASc 0 or 1 (men) and 1 or 2 (women)), the GARFIELD-AF risk score offered strong discriminatory value for all the endpoints when compared to CHA2DS2-VASc and HAS-BLED. The GARFIELD-AF tool also included the effect of OAC therapy, thus allowing clinicians to compare the expected outcome of different anticoagulant treatment decisions (i.e., No OAC, NOACs or VKAs). CONCLUSIONS: The GARFIELD-AF risk tool outperformed CHA2DS2-VASc at predicting death and non-haemorrhagic stroke, and it outperformed HAS-BLED for major bleeding in overall as well as in very low to low risk group patients with AF

Impact of atrial fibrillation on clinical outcomes among patients with coronary artery disease undergoing revascularisation with drug-eluting stents

Coronary artery disease (CAD) and atrial fibrillation (AF) are major determinants of morbidity and mortality. A combined treatment with antiplatelet agents and vitamin K antagonists limits the risk of stent thrombosis and stroke while increasing the rate of bleeding. The objective of this study was to investigate the impact of atrial fibrillation (AF) on long-term clinical outcomes in patients with CAD undergoing percutaneous coronary intervention (PCI) with drug-eluting stents (DES)

Severe renal impairment and stroke prevention in atrial fibrillation implications for thromboprophylaxis and bleeding risk.

The prevalence of atrial fibrillation (AF) in end-stage renal failure is high, with an increased risk of stroke among these patients with AF compared with the AF population without severe renal impairment. Many trials have shown the net clinical benefit of oral anticoagulation therapy for primary and secondary prevention of stroke in patient populations with AF. However, current stroke risk stratification schemes are based on studies that have deliberately excluded patients with severe renal impairment. Indeed, there are no large randomized controlled trials that assess the real risk/benefit of full intensity anticoagulation in patients with severe renal impairment. Also, rates of major bleeding episodes in anticoagulated hemodialysis patients with AF are high. These data are influenced by the lack of appropriate monitoring, the difficulties in maintaining the international normalized ratio target (variable between the studies), and an inaccurate bleeding classification. Thus, the limited available data may be difficult to apply to such a heterogeneous patient population, characterized by both an increased risk of bleeding and a hypercoagulability state, as seen in the patient population with severe renal impairment
