Introduction: Anticoagulant therapy can prevent adverse outcomes of Atrial fibrillation (AF), reducing the risk of stroke by 64% and death by 25%. The present study aimed to assess treatment adherence in elderly patients with non-valvular atrial fibrillation (NVAF) who were prescribed the vitamin K antagonist warfarin.   Materials and methods: In the present retrospective study, we analyzed the medical records of 202 elderly outpatients with NVAF aged between 65 and 74 years (mean ± SD: 68.7 ± 10.2 years).    Results: Problems associated with warfarin arose throughout the follow-up period. After 1 month of treatment, the number of patients taking warfarin had decreased to 71.3% of all patients; less than half of the patients (46%) were still taking the drug. In subsequent periods, the number continued to decrease; of all patients who had been prescribed warfarin with periodic international normalized ratio (INR) control, only 19 (9.4%) remained after 1 year. Our study revealed inadequate anticoagulation therapy in elderly patients, probably because most patients refused warfarin therapy because they could not control their INR. Moreover, significantly more rural residents than urban residents refused therapy (48 vs. 22; p < 0.05). Doctors underprescribed anticoagulants because they feared hemorrhagic complications in their patients.   Conclusion: The results of the present study showed that anticoagulants were underprescribed at the outpatient stage in centers of family medicine in our country. The main drug of choice for specialists remains warfarin, which only provides adequate therapy in a small number of patients (9.4%).

Background: Changes in daily vitamin K intake may contribute to marked variations in the International Normalized Ratio (INR) coagulation index in patients receiving oral warfarin anticoagulant therapy, with potentially serious adverse outcomes. Thus, patients receiving warfarin therapy are routinely counseled regarding this drug-nutrient interaction and are instructed to maintain consistent vitamin K intakes, though little quantitative information about this relationship is available. Objective: To determine the quantitative impact of variability in dietary vitamin K1 (phylloquinone) intake, assessed by a validated patient self-monitoring instrument, on weekly INR in patients receiving warfarin anticoagulant therapy. Methods: A prospective dietary assessment study was conducted at the Massachusetts General Hospital in Boston. Sixty outpatients (37 males and 23 females) were selected with a mean age 60.3 ± 16.8 years, who began oral warfarin anticoagulant therapy within 14 days prior to their first clinic visit to an outpatient anticoagulation therapy unit. Exclusion criteria included more than 2 drinks of alcohol per day, inability to speak English, and concurrent disease states affecting warfarin therapy such as liver disease and terminal illness. Over the five-week study period, participants recorded daily intakes in specified amounts of all food items appearing on a validated dietary self-assessment tool. Concomitant use of prescription and/or non-prescription medications was also obtained. Concurrent daily warfarin dose and adherence to the drug regimen, concomitant use of prescription and/or non-prescription medications known to interact with warfarin, and weekly INR were obtained. Week-to-week changes in vitamin K intake, warfarin dose, and INR were determined and cross-correlated. Results: Forty-three patients (28 males and 15 females) completed the study and 17 dropped out. Pearson’s correlation coefficient revealed the variability in INR and changes in vitamin K intake were inversely correlated (r = –0.600, p < 0.01). Multiple regression analysis (r = 0.848) indicated that a weekly change of 714 mug dietary vitamin K significantly altered weekly INR by 1 unit (p < 0.01) and a weekly change of 14.5 mg warfarin significantly altered weekly INR by 1 unit (p < 0.01) after adjustment for age, sex, weight, height, and concomitant use of medications known to interact with warfarin. Conclusions: Patients taking warfarin and consuming markedly changing amounts of vitamin K may have a variable weekly INR with potentially unstable anticoagulant outcomes.

Aim. To analyze anticoagulant therapy in elderly patients with non-valvular atrial fibrillation and ways to increase adherence in the work of a specialized team. Methods. The study followed 250 patients with non-valvular atrial fibrillation aged 65 to 74 years (mean age 70.74.39 years). The patients were divided into three groups: the first group included 105 people, who were prescribed warfarin in a retrospective study; the second group 57 people treated with rivaroxaban, and the third group 88 people treated with warfarin. The second and third groups were prospective study groups which were supervised by a specialized team of physicians. The groups were matched on sex and age, comorbidities. Statistical data analysis and mathematical processing were performed by using the methods of descriptive and variational statistics. Most parameters reported as absolute values and percentages, while quantitative data the 25th and 75th percentiles. Results. All patients included in the study had a high risk of developing thromboembolic complications by their CHA2DS2-VASc score (2) and a low risk of developing hemorrhagic complications on the HAS-BLED scale (average score 1.490.04). They were prescribed anticoagulant therapy. By the end of the year follow-up from the start of anticoagulant therapy, only 9.5% of patients were treatment adherent, in the second group 43.8%, in the third group 70.5% of patients. The reason for refusing to take warfarin in the vast majority of cases was the inability to control the international normalized ratio, medical contraindications, and the high cost of the drug in prescribing rivaroxaban. The results showed that the majority of patients with atrial fibrillation (90.5%) receive inadequate antithrombotic therapy in routine outpatient clinical practice. At the same time, in a very small number of patients (9.5%) receiving warfarin, this type of therapy can be considered adequate (60% or more of the stay time in the therapeutic range of international normalized ratio of 2.0 to 3.0). Conclusion. Anticoagulant therapy prescription under the supervision of a specialized team contributes to a significant improvement in treatment adherence (from 43.8 to 70.5%); promising in the future is the use of drugs from the group of new oral anticoagulants that do not require routine monitoring of coagulogram.

Background: he number of patients on warfarin therapy is rising steadily. Although warfarin is beneficial, it carries a high risk of bleeding, especially if the international normalized ratio (INR) values exceed 3.0. Currently, no warfarin initiation regimens have been developed for the Asian population, especially for Malaysians. Objective: This article describes the efficacy and safety of a new initiation regimen for warfarin among warfarin-naive patients. Method: Data were retrospectively collected from the ambulatory and inpatient settings. Results: A total of 165 patients who each had a target INR of 2.0 to 3.0 were included in the study. The mean age was 57.2 years and 94 patients were male. A total of 108 patients used Regimen 1 (5 mg/5 mg/3mg) and the rest of the patients used Regimen 2 (5 mg/3 mg/3 mg). Most patients used warfarin either for atrial fibrillation (52.1%) or for venous thromboembolism (29.7%). Overall, 88 of the patients had INR values above 50% from the baseline on Day 4. Additionally, 13 patients had INR values of >3.2, which required withholding and lower dose of warfarin. The predicted weekly maintenance warfarin dose (23 ± 0.5 mg/week) was found to have correlated closely with the actual maintenance dose (22.8 ± 0.5 mg/week; r2 = 0.75). Nearly two thirds (70.3%) of the patients achieved the target INR on Day 11. Conclusion: The warfarin initiation regimens in this study was simple, safe, and suitable to be used in both ambulatory and inpatient settings for managing warfarin therapy.

Background. Warfarin reduces the risk of thromboembolic events associated with atrial fibrillation (AF), but therapeutic persistence is suboptimal. Few studies have investigated the reasons for warfarin discontinuation in community practice. Methods. We used data from ORBIT-AF, the nation’s largest AF database, to examine patterns of warfarin discontinuation over a one-year period. Patients transitioned to non-warfarin oral anticoagulation therapy were excluded. We compared patient and provider characteristics between individuals who discontinued warfarin and those who persisted. Results. From June 2010 to August 2011, 10,126 AF patients 18 years or older were enrolled at 176 ORBIT-AF practices. Of these, 6,559 (64.8%) were taking warfarin at baseline and have follow-up data; 514 (7.8%) of these switched to dabigatran and were excluded from the analysis. Additionally, two patients without follow-up warfarin data were excluded from the analysis. Over one year, 587 patients (9.7%) discontinued warfarin therapy. Compared to persistent users, patients who discontinued warfarin were younger, less likely to be white, had lower stroke risk (CHADS 2 <2), were more likely to follow a rhythm control strategy, and were less likely to be managed in an anticoagulation clinic (Table 1). The most commonly reported reasons for warfarin discontinuation were physician preference (31.0%), other (18.7%), patient refusal/preference (13.6%), bleeding event (13.3%), frequent falls/frailty (7.3%), high bleeding risk (6.6%), and patient inability to adhere to/monitor therapy (2.9%). Conclusions. Discontinuation of warfarin is common among patients with atrial fibrillation. Patient and physician preference are major contributors to persistence on warfarin therapy.

OBJECTIVE: To determine the effect of daily consultation by a team of hospital pharmacists on the accuracy and rapidity of optimizing warfarin therapy. DESIGN: Comparison of a historical control cohort with a prospective cohort matched for treatment indication. SETTING: A 400-bed university teaching hospital. PATIENTS: Sixty consecutive patients hospitalized in 1992 and starting warfarin for the first time, with anticoagulation therapy managed by physicians, were compared with 60 patients matched for warfarin indication hospitalized in 1995, but with anticoagulation therapy managed with pharmacy consultation. RESULTS: Pharmacist management of initial warfarin therapy resulted in a significant reduction in the length of hospitalization compared with physician dosing, from 9.5 ± 5.6 days to 6.8 ± 4.4 days (p = 0.009). The number of patients and patient-days with international normalized ratio (INR) values >3.5 were reduced by pharmacist dosing from 37 patients and 142 days to 16 patients and 29 days, respectively (p < 0.001). Similarly, the number of patients and patient-days with INR >6.0 were reduced from 20 patients and 50 days to two patients and six days, respectively (p < 0.001). There were six documented bleeding complications in 1992 compared with one in 1995 (p = 0.11). The mean INR at discharge was significantly lower in the pharmacy surveillance group, 2.6 ± 0.58, compared with the physician cohort, 3.3 ± 2.1 (p = 0.07). Readmissions after discharge due to bleeding or recurrent thrombosis were reduced from five (at 1 mo) and 10 (at 3 mo) to two and five readmissions, respectively, by pharmacist intervention (p = 0.43). The number of patients with concurrently prescribed drugs known to significantly interact with warfarin was significantly lower (6 vs. 13; p = 0.02) in the pharmacy surveillance group. CONCLUSIONS: Among patients starting warfarin for the first time, daily consultation by a pharmacist significantly decreased the length of hospital stay and the number of patients who received excessive anticoagulation therapy. These findings translate into improved quality of care and potentially significant cost savings.

Background and Purpose: Unlike clinical atrial fibrillation (AF), the significance of subclinical AF (SCAF) burden in patients with permanent pacemakers has not been fully evaluated. Methods: We investigated whether the SCAF burden was associated with increased risks of composite adverse outcomes, including progression to clinical AF, ischemic stroke, myocardial infarction, heart failure-related hospitalization, or cardiac death, in patients without previous AF. To quantify the 6-month SCAF burden, the total cumulative time spent in SCAF during every 6-month follow-up was summed. Results: During the median 5.2-year follow-up, 496 consecutive permanent pacemaker patients were classified into the no SCAF (no SCAF episode in any device analysis; n=152), low-burden SCAF (6-month SCAF <24 hours in at least one device analysis; n=287), or high-burden SCAF (6-month SCAF ≥24 hours in at least 1 device analysis; n=57) groups. The risk of composite adverse outcomes was greatest in the high-burden SCAF group ( P <0.001) and was primarily driven by progression to clinical AF ( P <0.001) and ischemic stroke ( P <0.001). The presence of high-burden SCAF, which always preceded ischemic stroke events, was independently associated with composite adverse outcomes (odds ratio=20.1 [95% CI, 7.60−52.7], P <0.001) and progression to clinical AF (odds ratio, 36.2 [95% CI, 15.9−87.8], P <0.001). Conclusions: In permanent pacemaker patients without preexisting AF, the presence of high-burden SCAF was closely associated with increased risks of composite adverse outcomes, particularly progression to clinical AF and ischemic stroke. Therefore, prospective studies deserve to be performed on the optimal anticoagulation therapy for permanent pacemaker patients with both high-burden SCAF and high stroke risk.

Abstract Background Patients with atrial fibrillation (AF) commonly coexist with chronic kidney disease (CKD). Non-vitamin K antagonist oral anticoagulants (NOAC) are recommended for stroke prevention in patients with non-valvular atrial fibrillation (AF), and worsening renal function (WRF) as well as CKD is an important issue in using NOAC. However, little is known about the clinical outcomes of patients after WRF. Purpose We aimed to investigate outcomes after WRF in AF patients. Methods The Fushimi AF Registry is a community-based prospective survey of the AF patients in our city. Follow-up data including prescription status were available for 4,441 patients. Of them, 1,890 patients who have baseline and at least 1 follow-up creatinine clearance (CrCl) measurements, estimated by the Cockcroft-Gault formula, were analyzed in the present study. WRF was defined as a decrease of ≥20% from baseline CrCl measurement at any time point during follow-up. We evaluated demographics and outcomes after WRF in AF patients. Results During the median follow-up period of 2,194 days, mean CrCl decrease of 2.2 ml/min/year was observed and WRF occurred in 981 patients (51.9%). Patients with WRF were significantly more often female (with vs. without WRF; 40.3% vs. 35.4%; p=0.03), older (73.4 vs. 71.1 years of age; p&lt;0.01), more often paroxysmal type (49.9% vs. 47.1%; p&lt;0.01), and more likely to have prior stroke (17.9% vs. 12.7%; p&lt;0.01), heart failure (30.8% vs. 24.8%; p&lt;0.01), diabetes (31.7% vs. 27.1%; p=0.03), and coronary artery disease (19.9% vs. 12.1%; p&lt;0.01) than those without WRF. Co-existing of CKD and mean CrCl at baseline were comparable (37.4% vs. 36.9%; p=0.82, 65.3 vs. 63.5 ml/min; p=0.66, respectively). Mean CHA2DS2-VASc score was significantly higher in WRF patients (3.55 vs. 3.03; p&lt;0.01). On landmark analysis, all-cause mortality occurred in 135 patients (8.6 /100 person-years) after WRF and 82 patients (1.7 /100 person-years) without WRF, with an adjusted hazard ratio (HR) of 6.33 (95% confidence interval [CI], 4.33–9.50; p&lt;0.01), adjusted by sex, age, body weight, serum creatinine, type of AF, oral anticoagulant prescription and comorbidities. Stroke or systemic embolism occurred in 45 patients after WRF (3.0 /100 person-years) and 78 (1.7 /100 person-years) patients without WRF (adjusted HR 1.60 [95% CI, 1.04–2.49; p=0.03]) (Figure).

Background: Little data are available regarding differences in prognosis and health status between new-onset and prior atrial fibrillation (AF) among patients with acute myocardial infarction (AMI). Methods: The TRIUMPH study enrolled 4340 AMI patients who received longitudinal follow-up including SF-12 health status assessments through 1 year post-AMI. We compared 1-year mortality, rehospitalization, and functional status according to AF type (none, prior, new) after adjusting for differences in baseline characteristics. Results: A total of 212 AMI patients (4.9%) had prior AF and 254 (5.9%) had new-onset AF. Compared with no AF, new AF was associated with older age, male sex, first MI, worse baseline physical function, home atrioventricular nodal blocker use, and worse ventricular function (c-index 0.77). Rates of 1-year mortality were 6.2%, 14.5%, and 13.0%, and 1-year rehospitalization rates were 29.1%, 44.2%, and 36.8% for no, prior, and new AF, respectively. After multivariable adjustment, neither prior nor new AF was associated with increased 1-year mortality, and only prior AF was associated with increased risk of 1-year rehospitalization (Figure). After adjusting for baseline SF-12 physical function scores, patients with prior AF had lower 1-year scores than those with no AF (40.6 vs. 43.7, p <0.003), whereas patients with new AF had similar scores (42.9 vs. 43.7, p=0.36). Conclusion: New-onset AF during AMI is associated with a number of comorbidities but, unlike prior AF, is not associated with adverse outcomes. These results raise the question of whether AF is itself a cause of or simply a marker of comorbidities leading to downstream adverse outcomes after AMI.

Background: Atrial fibrillation (AF) may occur prior to or early in the course of acute pulmonary embolism (PE). The impact of AF on outcomes of patients with PE remains uncertain. Methods: Using the data from a large prospective multicenter registry of patients with objectively-confirmed PE (04/2014 to 01/2020), we identified three patient groups: 1) those with pre-existing AF 2) patients with newly identified AF within 2 days from the index PE (incident AF) and 3) patients without AF. We assessed the 90-day and 1-year risk of mortality and stroke in patients with AF, in unadjusted and multivariable adjusted models considering those without AF as referent. Results: Among 16,497 patients with PE, 792 had pre-existing AF. Compared with those without AF, patients with pre-existing AF, had increased odds of 90-day all-cause (Odds ratio [OR]: 2.81 (95% confidence interval [CI]: 2.33-3.38) and PE-related mortality (OR: 2.38, 95% CI: 1.37-4.14). After multivariable adjustment, pre-existing AF significantly increased the odds of all-cause mortality (OR: 1.91, 95% CI: 1.57-2.32) but not PE-related mortality (OR: 1.50; 95% CI: 0.85-2.66). Pre-existing AF was associated with increased hazard for ischemic stroke at 1-year follow-up (hazard ratio [HR]: 5.48; 95% CI: 3.10-9.69). Among 16,497 patients with PE, 445 developed incident AF within 2 days of acute PE. Incident AF was associated with increased odds of 90-day all-cause (OR: 2.28; 95% CI: 1.75-2.97) and PE-related (OR: 3.64; 95% CI: 2.01-6.59) mortality. Findings were similar in multivariable analyses and at 1-year follow-up (Figure). No patients with incident AF developed ischemic stroke. Conclusion: In patients with acute symptomatic PE, both pre-existing AF and incident AF predict an adverse clinical course, although the type of adverse outcomes may be different depending on the timing of AF onset.
