RESUMEN

The financial difficulties of parents have a negative impact on the health of their children. This problem is more pronounced in single mother families. There is limited research on low-income, single mothers and how interventions to help them address financial difficulties may also benefit their children. The purpose of this study was to evaluate the effect of a year-long financial education and coaching program on school absenteeism and health care utilization of children in employed, low-income, single mother households. This was a post hoc analysis of the Finances First study, a randomized controlled trial conducted in 2017-2020 examining the impact of a financial coaching and education program on economic stability and health outcomes in 345 low-income, single mothers. Either generalized estimating equations (GEEs) or generalized linear mixed models (GLMMs) were used to account for relationships between participants. For the continuous outcomes of child absenteeism, physician visits, emergency room visits, and hospitalization days, a linear mixed-effects model was used. The Finances First study demonstrated improvements in various financial strain measures. Compared to the control group, children of intervention group participants experienced 1 fewer day of school absence (p = 0.049) and 1 fewer physician visit (p = 0.032) per year, but no impact was seen on emergency room visits (p = 0.55) or hospitalizations (p = 0.92). Addressing social determinants of health in parents is necessary for improving child health outcomes.

RESUMEN

BACKGROUND: Fish oils are the most widely used nonvitamin, nonmineral dietary supplements in the United States. They are not over-the-counter medications and are neither approved nor indicated for treating disease. Patient knowledge and patterns of fish oil use are not well defined. OBJECTIVE: To determine cardiac patients' knowledge and patterns of fish oil use. METHODS: One thousand consecutive patients admitted to an in-patient cardiology service (2015-2017) taking fish oil dietary supplements or prescription omega-3 fatty acids were asked to complete an anonymous questionnaire concerning product knowledge and use. RESULTS: A total of 711 (71%) patients completed the questionnaire. Primary reasons for use included general health (34%), heart health (28%), arthritis (9%), and lipid disorders (8%). Few patients (14%) were advised to take fish oil products by a health-care provider. Only 2.5% were taking prescription omega-3 fatty acids. Only 26% knew the active ingredient in their fish oil product. Supplements were purchased through a nonpharmacy retail seller by 81% of respondents. CONCLUSIONS: Most cardiac patients consuming fish oil dietary supplements do so without medical supervision and without knowledge of the active ingredients. As most patients obtain supplements outside of a pharmacy, opportunities to monitor and educate patients remain a major challenge.

RESUMEN

Rivaroxaban is a direct oral anticoagulant (DOAC) indicated to reduce risk of stroke and systemic embolism in patients with non-valvular atrial fibrillation (AF). A discrepancy exists between the recommended dosage and real-world use of DOACs, especially rivaroxaban, thus putting patients at risk of thromboembolic events. METHODS: This retrospective study assessed real-world prescribing and patient adherence to dietary requirements during use of rivaroxaban in 116 patients with AF. Associations between prescriber specialty and the correct dosing and administration were assessed using the Chi-Square test. RESULTS: Most rivaroxaban prescriptions were ordered by cardiologists (50.9%). Sixty-nine patients (59.5%) were taking the right dose at the correct time with an adequate meal. Of the 47 (40.5%) taking rivaroxaban incorrectly, 39 (33.6%) had not been administered an adequate meal and eight (6.9%) were not prescribed the correct dose. Compared with other prescribers, patients were most likely to be taking the correct dose and administration when prescribed by cardiologists (72.9% versus 45.6%; p=0.003). Patients were least likely to be taking the correct dose and administration when prescribed by primary care providers (44.4% versus 69.0%; p=0.009). This difference was driven by patients who did not take the treatment with an adequate meal. CONCLUSION: Inappropriate prescribing, administration and non-adherence to DOACs can have devastating consequences. This highlights the importance of formal systematic education of patients prescribed DOACs across the whole health system. Future studies are warranted to explore the impact of non-adherence to rivaroxaban dietary requirements on clinical outcomes.

RESUMEN

STUDY OBJECTIVE: To compare the efficacy of amlodipine and valsartan in African-American patients with hypertension using ambulatory blood pressure monitoring (ABPM). DESIGN: Prospective, randomized, double-blind, crossover comparison study. SETTING: University-affiliated cardiac center clinic. PATIENTS: Twenty African-Americans (12 men, 8 women), with a history of uncomplicated hypertension (blood pressure > 140/90 mm Hg). INTERVENTION: Patients were randomized to receive amlodipine 5 or 10 mg/day or valsartan 80 or 160 mg/day for 8-10 weeks, depending on response. Dosages were titrated to achieve a blood pressure of 140/90 mm Hg or below. For patients whose blood pressures were not controlled, hydrochlorothiazide 12.5 mg/day was added to their regimens. Patients then underwent 24-hour ABPM. After an intervening washout period during which baseline blood pressure was reestablished, patients received the other treatment. MEASUREMENTS AND MAIN RESULTS: Mean +/- SD baseline blood pressure before the two ABPM periods were 155 +/- 12/100 +/- 8 mm Hg and 156 +/- 11/101 +/- 9 mm Hg, respectively. Fifteen (75%) patients achieved goal blood pressure with amlodipine and 14 (70%) with valsartan (p=0.62). Final daily dosages were as follows: amlodipine 5 mg in nine patients, 10 mg in five patients, and 10 mg plus hydrochlorothiazide in six patients; valsartan 80 mg in nine patients, 160 mg in four patients, and 160 mg plus hydrochlorothiazide in seven patients. Ambulatory blood pressure monitoring was not completed in three patients due to adverse effects: headache and dizziness (one patient each, amlodipine and valsartan) and hyperkalemia (one patient, valsartan). Four patients (20%) in each treatment group had drug-related adverse effects. Results of ABPM including averages for 24-hour, daytime, nighttime, first 4 hours, and last 8 hours, and trough:peak ratios were not significantly different between the amlodipine- and valsartan-based treatments. CONCLUSION: Based on both clinic blood pressure measurements and ABPM data, amlodipine and valsartan produced similar reductions in blood pressure in African-American patients with uncomplicated hypertension.

RESUMEN

AIM: Suboptimal adherence to medications taken chronically for secondary prevention of cardiovascular disease (CVD, e.g., aspirin) continues to burden the healthcare system despite the well-established benefits of prevention. We conducted a literature search to examine patient adherence to medications for secondary prevention of CVD-as evaluated by prescription refill data, electronic medication monitors, pill counts, and physiologic markers-to better identify an unmet need for measures to improve patient adherence to these therapies. METHODS: English-language articles were obtained from the PubMed database using the following key words or combinations thereof "adherence," "compliance," "secondary prevention," and "cardiovascular disease." Publications that provided adherence data only for primary prevention, lacked data on medication adherence (e.g., focus on guideline adherence), emphasized quality-of-care outcomes, or focused on outcomes of acute interventions were excluded. RESULTS: Multiple patient-, disease-, and treatment-related factors may contribute to poor adherence to treatment regimens, and therefore, a multifactorial approach will likely be needed to improve compliance with prescribed treatments for CVD. Although no magic bullet exists to assure full adherence, adherence programs coupled with patient counseling and education (inclusive of over-the-counter therapies), along with treatments that are less complex or avoid bothersome adverse effects, are more likely to be associated with successful outcomes. CONCLUSION: Given the burden of CVD to the community and the healthcare system, nonadherence to CVD-preventative medications such as aspirin remains a substantial area of unmet need and represents a key opportunity for the development of quality-of-care enhancement programs to improve health outcomes in this patient population.

RESUMEN

Depressed patients are at increased risk of cardiovascular (CV) disease (CVD) and those with concomitant depression and CVD are at increased risk of death. The safety and efficacy of antidepressants in patients with CVD varies greatly between the agent used and type of disease. This review will summarize the CV adverse effect and drug interaction profile of antidepressants and discuss the use of antidepressants in CVD patients. We searched MEDLINE, PubMed, CINAHL, Web of Science, PsycINFO, and The Cochrane Library from inception to June 2014 to identify studies relevant to antidepressant use in patients with CVD. Primary references from the identified articles were also evaluated for inclusion. Descriptive analysis was performed for the included studies in this review. Orthostatic hypotension was more common with tricyclic antidepressants (TCAs), trazodone and monoamine oxidase inhibitors (MAOIs). Hypertension can be significant with serotonin norepinephrine reuptake inhibitors (SNRIs) and MAOIs. The potential for QT prolongation is present with TCAs, certain selective serotonin reuptake inhibitors (SSRIs), certain SNRIs and mirtazapine. Due to its low risk of drug-drug interactions, adverse effect profile and potential for beneficial antiplatelet activity, sertraline could be considered the choice antidepressant for patients with ischemic heart disease. SSRIs and potentially SNRIs are relatively safe and effective options for patients with heart failure. In patients at high risk for ventricular arrhythmias, bupropion has the overall lowest risk for QT prolongation. TCAs and MAOIs should be avoided in patients with concomitant CVD. In conclusion, due to the increased morbidity and mortality associated with comorbid CVD and depression, practitioners should readily assess and initiate management of depression in such patients. The choice of antidepressant should take into account the potential CV impact of the various agents balancing safety and efficacy.

RESUMEN

This study was designed to assess the relationship between plasma lipid levels and endothelial function in Asian Indians without cardiovascular risk factors living in the United States. While traditional risk factors do not account for the increased incidence of coronary heart disease (CHD) in Asian Indians, low high-density lipoprotein (HDL) cholesterol, elevated triglycerides, elevated lipoprotein (a), and insulin resistance are consistently found in Asian Indians with CHD. Endothelial function was measured in 86 healthy Asian Indians (mean age 33 years) free of cardiac risk factors with LDL levels<160 mg/dL. Subjects were divided into two groups on the basis of HDL levels (low HDL<40 mg/dL and normal HDL-40 mg/dL). Endothelial function during reactive hyperemia was significantly impaired in Asian Indians in the low HDL group. After covariate adjustment, NTG-induced brachial vasodilation was not different between patients in the two HDL groups. These data indicate that low HDL is associated with endothelial dysfunction in this population.

RESUMEN

OBJECTIVES: This prospective, randomized, double-blind, placebo-controlled study compared the efficacy and safety of amiodarone and sotalol in the prevention of atrial fibrillation (AF) following open heart surgery. BACKGROUND: The incidence of supraventricular arrhythmias following open heart surgery ranges from 20% to 40%, with AF being the most common. Both amiodarone and sotalol have been shown to be effective in reducing postoperative arrhythmias, but no direct comparison of these agents has been conducted. METHODS: A total of 160 patients were randomized, of whom 134 underwent coronary artery bypass graft surgery (CABG) alone, 17 underwent CABG and concomitant aortic valve replacement surgery (AVR), 9 underwent AVR only, and 1 patient's surgery was canceled. Patients with signs or symptoms of congestive heart failure (CHF), ejection fraction < or =30%, estimated creatinine clearance <30 mL/min, or serum creatinine > or =2.5 mg/dL were excluded. Patients were randomized to receive either sotalol 80 mg 2 times per day (n = 76) or intravenous amiodarone 15 mg/kg over 24 hours followed by oral amiodarone 200 mg 3 times per day (n = 83). Study drug was started at the time of surgery and continued for 7 days or until discharge, whichever came first. RESULTS: AF occurred in 17% of patients randomized to amiodarone and 25% of the patients randomized to sotalol (P =.21). However, the duration of AF was significantly shorter in amiodarone-treated patients (169 +/- 224 min) compared to sotalol treated patients (487 +/- 505 min; P =.04). In a subgroup analysis, the incidence of AF in patients undergoing AVR or CABG with AVR was significantly less with amiodarone (1/15, 7%) compared to sotalol (9/11, 82%) (P <.001). Blood pressure was lower immediately after surgery with amiodarone but comparable to sotalol at 24 hours. Of the hemodynamic indices measured, only stroke volume was significantly lower in patients randomized to sotalol at 24 hours (P =.035). CONCLUSIONS: Amiodarone and sotalol share similar efficacy and safety in reducing postoperative AF. Hemodynamic effects were similar between both drugs at 24 hours, with the exception that stroke volume was lower in sotalol-treated patients. In patients undergoing more complex surgery, postoperative AF occurred more frequently with sotalol than with amiodarone.

RESUMEN

PURPOSE: Patients who continue to smoke following coronary artery bypass graft surgery (CABG) have substantially poorer outcomes than patients able to stop smoking after CABG. This study evaluated the effectiveness of two smoking cessation treatment strategies in patients undergoing CABG. METHODS: Two smoking cessation treatment strategies were compared in smokers who underwent CABG. In the conservative treatment strategy, smokers undergoing CABG were followed up prospectively at monthly intervals. Patients who started smoking again at any time in the year following CABG were asked to enroll in an 8-week smoking cessation program. In the aggressive treatment strategy, smokers undergoing CABG were asked to enroll in an 8-week smoking cessation program starting immediately after hospital discharge. The structure and makeup of the smoking cessation program used in the conservative and aggressive treatment strategies were identical. The primary study outcome was smoking status assessed by self-report and confirmed by expired carbon monoxide at 1.5 months, 3 months, 6 months, and 12 months after surgery. RESULTS: Nineteen patients were enrolled in the conservative treatment strategy, with 2 patients unavailable for follow-up prior to the first follow-up visit. Of the remaining 17 patients, 14 patients (82%) resumed smoking at an average of 10.3 weeks after CABG. Eleven of these 14 patients (79%) agreed to participate in the smoking cessation program. Based on evaluable patients, 10 of the 17 patients (59%) in the conservative strategy group were not smoking at the 12-month follow-up. Twenty patients were enrolled in the aggressive treatment strategy. All patients agreed to participate in the smoking cessation program. All patients were available for follow-up. At the 12-month follow-up, 17 of 29 patients (85%) in this treatment strategy were not smoking. Point prevalence and continuous abstinence cessation rates were significantly greater in the aggressive treatment strategy compared to the conservative treatment strategy at all follow-up intervals after CABG. CONCLUSION: Based on our findings in a small number of patients, an aggressive smoking cessation intervention is associated with a superior smoking cessation rate compared to a conservative treatment strategy in smokers undergoing CABG. A larger study will be needed to confirm that an early aggressive smoking cessation intervention should be provided to all smokers undergoing CABG.

RESUMEN

PURPOSE: Atrial fibrillation (AF) is the most common arrhythmic complication following coronary artery bypass graft surgery (CABG). The efficacy and safety of esmolol and diltiazem were compared in patients with post-CABG AF. METHODS: This study was a retrospective medical record review of consecutive patients with post-CABG AF > or =15 min in duration with a ventricular rate > or =110 b.p.m. who received either i.v. esmolol (n = 59) or i.v. diltiazem (n = 48) with or without concomitant digoxin therapy at a single university-affiliated teaching hospital. Treatment success was defined as either cardioversion to sinus rhythm or a reduction in the ventricular rate to < or =90 b.p.m. at 24 h after the start of therapy. Time to treatment success and the occurrence of adverse effects were considered secondary outcomes. RESULTS: A total of 107 patients with post-CABG AF were treated with i.v. esmolol (n = 59) or i.v. diltiazem (n = 48). The mean maximum dose of esmolol and diltiazem were 115 +/- 38 microg/kg/min and 11.2 +/- 3.5 mg/h, respectively. The average duration of the esmolol and diltiazem infusions were 19.3 +/- 8.5 h and 20.1 +/- 11.3 h, respectively. Based on the combined efficacy endpoint of cardioversion or ventricular rate control, esmolol was significantly more effective than diltiazem (90% vs 77%; p = 0.038). Time to treatment success was significantly better for esmolol than diltiazem at all time points (1, 2, 4, 6, 12, and 24 h post-treatment). The overall incidence of adverse effects was 44% with esmolol and 60% with diltiazem (p = 0.04). Rates of drug discontinuance for adverse effects were significantly less for esmolol (20%) compared with diltiazem (38%) (p = 0.04). CONCLUSIONS: Esmolol is significantly more effective than diltiazem in the management of post-CABG AF. More patients converted to sinus rhythm with esmolol as compared to diltiazem. Esmolol was associated with fewer adverse effects than diltiazem, including adverse effects leading to drug discontinuance. Due to study design limitations (retrospective data collection), an adequately powered randomised, controlled trial is needed to confirm these preliminary findings.

RESUMEN

Atopic asthma is a chronic inflammatory disorder of the airways where upon exposure to allergens, the body mounts an immune response. This disease is associated with an increase in the number of Th2 (T helper type 2) cells and Th2 cytokines and a decrease in the number of Th1 (T helper type 1) cells and Th1 cytokines. Histamine plays an important role in the pathogenesis of atopic asthma through differential regulation of T helper lymphocytes. Histamine enhances the secretion of Th2 cytokines such as IL-4 (interleukin-4), IL-5, IL-10 and IL-13 and inhibits the production of Th1 cytokines IL-2 and IFNgamma (interferon-gamma) and monokine IL-12. It has been shown that histamine can modulate the cytokine network through upregulation of PGE(2) (prostaglandin E(2)) and NO (nitric oxide). Histamine also affects cytokine production via H2 receptors and through the activation of PKA (protein kinase A). We have also demonstrated that the Jak-STAT (Janus kinase-signal transducers and activators of transcription) pathway is involved in histamine-mediated regulation of Th2 cytokines IL-5, IL-10, IL-13 and Th1 cytokine IFNgamma. While standard treatment of asthma consists of beta-receptor agonists and inhaled corticosteroids, the elucidation of histamine's control over the cytokine network and the Th1/Th2 balance provides a basis for the potential use of antihistamines in the prevention and treatment of atopic asthma. Several other anti-allergic agents to modulate the Th1/Th2 balance are under current investigation based on this paradigm. These include cytokines, cytokine antagonists, anti-IgE, and vaccinations. As more advances are made in our understanding of histamine and its control over the Th1/Th2 balance, the use of new therapeutic targets such as these will play a prominent role in disease management.

RESUMEN

STUDY OBJECTIVE: To evaluate the efficacy of reteplase administration in clearing hemodialysis catheters. DESIGN: Open-label, uncontrolled, observational trial. SETTING: University medical center. PATIENTS: Thirty-four patients with end-stage renal disease undergoing long-term hemodialysis. INTERVENTION: Patients had dual-lumen, cuffed, tunneled dialysis catheters placed for long-term vascular access. Reteplase 3 U was instilled into each catheter lumen (total dose 6 U) in the first 20 episodes, 2 U in each catheter lumen (total dose 4 U) in the next 20, and 0.5 U in each catheter lumen (total dose 1 U) in the final 45. MEASUREMENTS AND MAIN RESULTS: Over 12 months, 85 episodes of catheter dysfunction were documented. Catheter dysfunction was defined as absence of flow from the catheter lumen, inability to aspirate heparin from the lumen, blood flow rates below 150 ml/minute, or venous pressure greater than 250 mm Hg at blood flow rates below 200 ml/minute. Reteplase was instilled into the catheter lumens and allowed to dwell there until the next hemodialysis session. Successful catheter recanalization was defined as return of aspiration and infusion function allowing dialysis to be completed at blood flow rates above 300 ml/minute. Reteplase restored catheter function in 74 (87%) instances of catheter dysfunction. In the first 40 episodes in which 4- or 6-U doses were given, catheter function was restored in 36 instances (90%). There was no difference in restoration of catheter function between 4 U (18/20, 90%) and 6 U (18/20, 90%). In the last 45 cases in which 1 U was administered, function was restored in 38 catheters (84%). Mean overall dwell times were not different between the first 40 (32 +/- 7 hrs) and the last 45 episodes (33 +/- 10 hrs). The overall mean duration of catheter patency was 45 +/- 39 days. Durations of patency in the three dose groups were not significantly different (44 +/- 38, 46 +/- 40, 45 +/- 39 days). No patient suffered adverse effects related to reteplase. CONCLUSION: Reteplase installation in dysfunctional hemodialysis catheters was effective in restoring catheter function in 87% of episodes. A dose of 1 U appears to be as effective as 4 and 6 U.

RESUMEN

Fingernail clubbing and discoloration frequently indicate serious pulmonary, cardiovascular, and gastrointestinal pathologies. A 76-year-old Caucasian man developed clubbing of the fingernails and discoloration of both the fingernails and toenails after 27 days of treatment with the angiotensin II receptor blocker (ARB) losartan 50 mg/day. Even though this therapy was switched to valsartan, the nail changes persisted for another 6 months. The patient's therapy then was changed to captopril, and the changes gradually subsided over 17 months. An extensive literature search revealed no reports of this effect in association with ARBs. However, one manufacturer had received spontaneous reports. Despite careful consideration of other possible causes of the patient's symptoms, the temporal association with the start and discontinuation of ARB therapy suggests a possible drug-related adverse event.

RESUMEN

STUDY OBJECTIVE: To compare the lipid-lowering effects of gemfibrozil and fenofibrate in patients with dyslipidemic coronary heart disease. DESIGN: Open label, fixed-dosage, retrospective-prospective, one-way crossover from gemfibrozil to fenofibrate. SETTING: University-affiliated outpatient clinics. PATIENTS: Eighty patients with coronary heart disease with a baseline low-density lipoprotein cholesterol (LDL) level above 130 mg/dl or a triglyceride level of 200 mg/dl or higher who had been receiving gemfibrozil 600 mg twice/day. Thirty-nine (49%) patients had received concomitant therapy with a 3-hydroxy-3-methylglutaryl coenzyme A reductase inhibitor (statin) for a minimum of 9 months. INTERVENTION: All patients received gemfibrozil 600 mg twice/day for at least 3 months before being switched to fenofibrate 201 mg/day. Patients receiving concomitant statin therapy before crossover continued the statin at the same dosage after crossover. Before crossover, a fasting lipid profile was determined and patients were queried about the side effects of lipid-lowering therapy. A repeat fasting lipid profile was obtained 12 weeks after the crossover. MEASUREMENTS AND MAIN RESULTS: Patients were stratified into those receiving versus those not receiving concomitant statin therapy. In both of these groups, fenofibrate was associated with significantly greater reductions in total cholesterol, LDL, and triglycerides than gemfibrozil (all p < 0.001). In addition, fenofibrate was associated with a significantly greater increase in high-density lipoprotein cholesterol (HDL) than gemfibrozil (p < 0.001). No patients reported new-onset adverse effects after the crossover. CONCLUSIONS: Compared with gemfibrozil, fenofibrate produced significantly greater reductions in total cholesterol, LDL, and triglycerides and significantly greater increases in HDL. These changes were evident in patients receiving and not receiving concomitant statin therapy.

RESUMEN

BACKGROUND: Heart failure is one of the most common reasons for hospital admissions in patients aged 65 years and older, with an estimated 1 million hospitalizations annually. In 2010, health care expenditures for heart failure were estimated to be $32 billion. Nonadherence to medications and lifestyle contributes to hospital admissions in up to one-third of patients. Efforts to reduce readmissions are of critical importance. Pharmacist involvement in the management of heart failure patients has been shown to reduce heart failure hospitalizations, with trends towards a reduction in mortality. Literature is scarce on instruments that clinicians can use to identify patients at risk for medication nonadherence. OBJECTIVES: To (a) describe factors that predict medication adherence for patients with heart failure, (b) evaluate the impact and value of pharmacist interventions on adherence and outcomes, and (c) assess tools to predict medication nonadherence in heart failure patients. METHODS: From inception to September 2013, a search was conducted in the databases MEDLINE, PubMed, CINAHL, and The Cochrane Library to identify relevant studies for 3 separate searches, identifying predictors of medication adherence in heart failure patients, pharmacist involvement to impact medication adherence, and tools to predict medication nonadherence in this population. RESULTS: Many significant predictors of both medication adherence and nonadherence have been identified in heart failure patients. Studies evaluating the effect of pharmacist involvement in the management of heart failure demonstrated improvements in medication adherence that dissipated once the intervention was withdrawn. The Morisky Medication Adherence Scale and the Merck Adherence Estimator are simple and practical tools that may be useful for identifying nonadherence in heart failure patients. CONCLUSIONS: Clinicians should be cognizant of factors that may affect medication adherence in heart failure patients and be aware of instruments available to predict the risk for medication nonadherence. Pharmacist interventions should be part of a multidisciplinary system of care initiated at discharge that involve personal contact and are continued indefinitely in order to sustain these benefits.

RESUMEN

Numerous clinical trials testing the efficacy of aspirin for the secondary prevention of cardiovascular disease have been published. We reviewed the literature pertaining to aspirin dose in acute coronary syndrome patients. Clinical trials assessing the comparative efficacy of different doses of aspirin are scarce. This complex antiplatelet therapy landscape makes it difficult to identify the best aspirin dose for optimizing efficacy and minimizing risk of adverse events, while complying with the various guidelines and recommendations. Despite this fact, current evidence suggests that aspirin doses of 75-100 mg/day may offer the optimal benefit:risk ratio in acute coronary syndrome patients.

RESUMEN

BACKGROUND: Ranolazine is a novel antianginal medication approved for the treatment of chronic angina. There are only limited data concerning the efficacy of ranolazine in reducing healthcare resource utilization in patients with refractory angina pectoris. OBJECTIVE: The primary objective of this analysis was to evaluate the efficacy and safety of ranolazine in refractory angina pectoris. In addition, the impact of ranolazine on healthcare resource utilization was assessed. METHODS: Consecutive patients with refractory angina pectoris treated with ranolazine at two cardiology practices in the state of Nebraska were included in this analysis. The Canadian Cardiovascular Society (CCS) angina class and frequency and type of healthcare resource consumption were determined during the 12 months prior to and the 12 months after initiation of ranolazine. RESULTS: A total of 150 pts (64 % men) with a mean age of 66 ± 12 years were included in this analysis. All patients had previously undergone coronary revascularization. Nitrates, ß-adrenoceptor antagonists (ß-blockers), and calcium antagonists (calcium channel blockers) were being used in 83, 97, and 75 % of patients, respectively. During ranolazine treatment, a significant improvement in CCS angina class was observed, with 23 patients improving by one class and no patient experiencing a deterioration in functional class (p = 0.025). A total of 53 side effects occurred in 28 (19 %) patients receiving ranolazine. Of those patients with side effects, four required dose reduction and seven required drug discontinuation. The frequency of clinic visits and emergency room visits was lower during ranolazine treatment, but the differences in frequency were not significant. The number of patients hospitalized and the number of hospitalizations were significantly lower during ranolazine therapy than in the pre-ranolazine study period (p = 0.002). CONCLUSION: Ranolazine improved the CCS angina class and reduced hospitalizations over a 12-month follow-up period in a group of patients with difficult-to-treat refractory angina pectoris.

RESUMEN

An important component to optimal health is quality of life (QOL). Several healthy lifestyle behaviors have independently shown to improve QOL. The simultaneous implementation of multiple lifestyle behaviors is thought to be difficult, and the current literature lacks the assessment of multiple lifestyle behaviors simultaneously with respect to the effect on QOL. This current pilot study sought to develop a method to quantify multiple lifestyle behaviors into a single index value. This value was then measured with QOL for a possible correlation. The results showed that it is possible to convert multiple raw healthy lifestyle data points into a composite value and that an improvement in this value correlates to an improved QOL. After 12 months of participation in a cardiovascular risk reduction program, study participants (N = 35) demonstrated a 37.4% (P < 0.001) improvement in the composite lifestyle index (CLI). The improved CLI demonstrated a correlation with a statistically significant improvement in how participants rated their overall health in 12 months (r = 0.701, P < 0.001) as well as the number of self-reported unhealthy days per month in 12 months (r = -0.480, P = 0.004).

RESUMEN

Antiplatelet therapy is used widely with proven benefit for the prevention of further ischemic cardiac complications in patients with known coronary artery disease (CAD) and a history of acute coronary syndrome (ACS). The limitations of conventional antiplatelet therapy with aspirin, clopidogrel, or prasugrel, as well as the fact that rates of recurrent ischemic events still remain high with use of these agents, underscore the need to investigate alternate agents that may further reduce event rates while limiting bleeding risk. The selection of antiplatelet therapy is further influenced by the following: ticagrelor was approved in July 2011 by the United States Food and Drug Administration (FDA), and clopidogrel is slated to become available as a generic productin 2012. We provide an overview of emerging agents for the treatment of CAD and ACS, including the reversible P2Y(12) antagonists ticagrelor, cangrelor, and elinogrel, and a new class of oral protease-activated receptor-1 (PAR-1) inhibitors, vorapaxar and atopaxar.The recently approved P2Y(12) antagonists prasugrel and ticagrelor demonstrate enhanced ability to prevent adverse cardiac outcomes. However, this comes at a cost of a potential increased risk of bleeding. New adverse effects have also emerged, including dyspnea for all of the reversible P2Y(12) antagonists (ticagrelor, cangrelor, and elinogrel) and ventricular pauses for ticagrelor. In addition, the newer P2Y(12) antagonists have a faster onset and offset. Two of these agents, cangrelor and elinogrel, are available as intravenous formulations, which may provide additional benefits in patients who undergo coronary artery bypass graft (CABG) surgery. Trials with the PAR-1 inhibitors have also shown trends toward reductions in cardiac events, but not without the possibility of increased bleeding. More than ever, as the arsenal of antiplatelet therapy expands, health care providers need to understand the pharmacologic and pharmacodynamic differences between conventional and emerging antiplatelet therapies for patients with ACS and CAD. Health care providers must also carefully assess patient-specific factors such as risk of thrombosis, concomitant disease states, age, drug adherence, and aspirin dose, and plan for those patients who will be undergoing CABG when selecting antiplatelet therapy in order to optimally balance bleeding and thrombosis risk.
