The sensitivity of graphic trends in differentiating sinus and supraventricular tachycardia.

BACKGROUND: The use of cardiac telemetry in the inpatient setting is widespread and has become integral in managing hospitalized patients. Telemetry is used to monitor patients with brady- and tachyarrhythmias. While most of the focus is on the rhythm strip data, a significant utility remains in analyzing the graphic heart rate trends. We specifically focused on the shape of the curve (rectangle or bell) of the heart rate over time to differentiate sinus tachycardia (ST) and supraventricular tachycardia (SVT). We hypothesized that identifying the shape of the graphic trend would improve the accuracy of diagnosis. METHODS: To demonstrate the simplicity of employing this method for improving the diagnosis of arrhythmia, we had senior medical students evaluate the telemetry strips and graphical trends. We gathered data from the medical student interpretation of 82 strips of in-hospital cardiac telemetry and asked them to differentiate ST and SVT based on the shape of the graphic trend. Each rhythm strip and the graphic trend was interpreted by two clinical cardiac electrophysiology attending physicians and confirmed on a 12­lead electrocardiogram. RESULTS: When students were asked to choose between ST and SVT based on the telemetry rhythm strip without graphic trends, 73% of their answers were correct. Diagnostic accuracy improved to 96% correct with the addition of the graphic trend. Depending on the telemetry rhythm strip alone, sensitivity to detect SVT was 75%, with 68% specificity. With the addition of the graphical trend, sensitivity improved to 98% and specificity 100%. CONCLUSION: Review of graphical trends, specifically the analysis of onset and offset, allows novice ECG readers to improve the ability to distinguish between ST and SVT.

Mechanisms linking preterm birth to onset of cardiovascular disease later in adulthood.

Cardiovascular disease (CVD) rates in adulthood are high in premature infants; unfortunately, the underlying mechanisms are not well defined. In this review, we discuss potential pathways that could lead to CVD in premature babies. Studies show intense oxidant stress and inflammation at tissue levels in these neonates. Alterations in lipid profile, foetal epigenomics, and gut microbiota in these infants may also underlie the development of CVD. Recently, probiotic bacteria, such as the mucin-degrading bacterium Akkermansia muciniphila have been shown to reduce inflammation and prevent heart disease in animal models. All this information might enable scientists and clinicians to target pathways to act early to curtail the adverse effects of prematurity on the cardiovascular system. This could lead to primary and secondary prevention of CVD and improve survival among preterm neonates later in adult life.

Frequency of in-hospital adverse outcomes and cost utilization associated with cardiac resynchronization therapy defibrillator implantation in the United States.

BACKGROUND: The utilization of cardiac resynchronization therapy defibrillator (CRT-D) has increased significantly, since its initial approval for use in selected patients with heart failure. Limited data exist as for current trends in implant-related in-hospital complications and cost utilization. The aim of our study was to examine in-hospital complication rates associated with CRT-D and their trends over the last decade. METHODS AND RESULTS: Using the Nationwide Inpatient Sample, we estimated 378 248 CRT-D procedures from 2003 to 2012. We investigated common complications, including mechanical, cardiovascular, pericardial complications (hemopericardium, cardiac tamponade, or pericardiocentesis), pneumothorax, stroke, vascular complications (consisting of hemorrhage/hematoma, incidents requiring surgical repair, and accidental arterial puncture), and in-hospital deaths described with CRT-D, defining them by the validated International Classification of Diseases, Ninth Revision, Clinical Modification diagnosis code. Mechanical complications (5.9%) were the commonest, followed by cardiovascular (3.6%), respiratory failure (2.4%), and pneumothorax (1.5%). Age (≥65 years), female gender (OR, 95% CI; P value) (1.08, 1.03-1.13; 0.001), and the Charlson score ≥3 (1.52, 1.45-1.60; <0.001) were significantly associated with increased mortality/complications. CONCLUSIONS: The overall complication rate in patients undergoing CRT-D has been increasing in the last decade. Age (≥65), female sex, and the Charlson score ≥3 were associated with higher complications. In patients who underwent CRT-D implantation, postoperative complications were associated with significant increases in cost.

Variability in utilization of drug eluting stents in United States: Insights from nationwide inpatient sample.

OBJECTIVES: We studied the trends and predictors of drug eluting stent (DES) utilization from 2006 to 2011 to further expound the inter-hospital variability in their utilization. BACKGROUND: We queried the Healthcare Cost and Utilization Project's Nationwide Inpatient Sample (NIS) between 2006 and 2011 using ICD-9-CM procedure code, 36.06 (bare metal stent) or 36.07 (drug eluting stents) for Percutaneous Coronary Intervention (PCI). Annual hospital volume was calculated using unique identification numbers and divided into quartiles for analysis. METHODS AND RESULTS: We built a hierarchical two level model adjusted for multiple confounding factors, with hospital ID incorporated as random effects in the model. About 665,804 procedures (weighted n = 3,277,884) were analyzed. Safety concerns arising in 2006 reduced utilization DES from 90% of all PCIs performed in 2006 to a nadir of 69% in 2008 followed by increase (76% of all stents in 2009) and plateau (75% in 2011). Significant between-hospital variation was noted in DES utilization irrespective of patient or hospital characteristics. Independent patient level predictors of DES were (OR, 95% CI, P-value) age (0.99, 0.98-0.99, <0.001), female(1.12, 1.09-1.15, <0.001), acute myocardial infarction(0.75, 0.71-0.79, <0.001), shock (0.53, 0.49-0.58, <0.001), Charlson Co-morbidity index (0.81,0.77-0.86, <0.001), private insurance/HMO (1.27, 1.20-1.34, <0.001), and elective admission (1.16, 1.05-1.29, <0.001). Highest quartile hospital (1.64, 1.25-2.16, <0.001) volume was associated with higher DES placement. CONCLUSION: There is significant between-hospital variation in DES utilization and a higher annual hospital volume is associated with higher utilization rate of DES. © 2015 Wiley Periodicals, Inc.

Intravascular Ultrasound in Lower Extremity Peripheral Vascular Interventions: Variation in Utilization and Impact on In-Hospital Outcomes From the Nationwide Inpatient Sample (2006-2011).

PURPOSE: To examine the impact of intravascular ultrasound (IVUS) utilization during lower limb endovascular interventions as regards postprocedural complications and amputation. METHODS: The study cohort was derived from the Healthcare Cost and Utilization Project Nationwide Inpatient Sample database between the years 2006 and 2011. Peripheral endovascular interventions were identified using appropriate ICD-9 procedure codes. Two-level hierarchical multivariate mixed models were created. The co-primary outcomes were in-hospital mortality and amputation; the secondary outcome was postprocedural complications. Model results are given as the odds ratio (OR) and 95% confidence interval (CI). Hospitalization costs were also assessed. RESULTS: Overall, among the 92,714 patients extracted from the database during the observation period, IVUS was used in 1299 (1.4%) patients. IVUS utilization during lower extremity peripheral vascular procedures was independently predictive of a lower rate of postprocedural complications (OR 0.80, 95% CI 0.66 to 0.99, p=0.037) as well as lower amputation rates (OR 0.59, 95% CI 0.45 to 0.77, p<0.001) without any significant impact on in-hospital mortality. Multivariate analysis also revealed IVUS utilization to be predictive of a nonsignificant increase in hospitalization costs ($1333, 95% CI -$167 to +$2833, p=0.082). CONCLUSION: IVUS use during lower limb endovascular interventions is predictive of lower postprocedural complication and amputation rates with a nonsignificant increase in hospitalization costs.

Clinical Application of Fractional Flow Reserve-Guided Percutaneous Coronary Intervention for Stable Coronary Artery Disease.

Revascularization in stable ischemic heart disease (SIHD) is indicated in patients on optimal medical therapy with angina and/or demonstrable ischemia and a significant stenosis in one or more epicardial coronary arteries. Angiography alone, however, cannot accurately determine the hemodynamic significance of coronary lesions, particularly those of intermediate stenosis severity. A lesion may appear significant on coronary angiogram but may not have functional significance. Percutaneous coronary intervention (PCI) of functionally insignificant coronary artery lesions may have serious consequences; therefore, judicious decision-making in the cardiac catheterization laboratory is indicated. For this reason, it is becoming increasingly important to show that a stenosis is capable to induce myocardial ischemia prior to intervention. Fractional flow reserve (FFR) has emerged as a useful tool for this purpose. In this review, we will briefly discuss the principle of FFR, current evidence and rationale supporting its use, and comparison with other modalities.

Asthma: Hospitalization Trends and Predictors of In-Hospital Mortality and Hospitalization Costs in the USA (2001-2010).

BACKGROUND: In the last decade, the proportion of people with asthma in the USA grew by nearly 15%, with 479,300 hospitalizations and 1.9 million emergency department visits in 2009 alone. The primary objective of our study was to evaluate in-hospital outcomes in patients admitted with asthma exacerbation in terms of mortality, length of stay (LOS) and hospitalization costs. METHODS: We queried the HCUP's Nationwide Inpatient Sample (NIS) between 2001 and 2010 using the ICD9-CM diagnosis code 493 for asthma (n = 760,418 patients). The NIS represents 20% of all hospitals in the USA. Multivariate logistic regression analysis was used to evaluate predictors of in-hospital mortality. LOS and hospitalization costs were also analyzed. RESULTS: The overall LOS was 3.9 days and as high as 8.3 days in patients requiring mechanical ventilation. LOS has decreased in recent years, though it continues to be higher than in 2001. The hospitalization cost increased steadily over the study period. The overall in-hospital mortality was 1% and as high as 9.8% in patients requiring mechanical ventilation. Multivariate predictors of longer LOS, higher hospitalization costs and in-hospital mortality included increasing age and hospitalizations during the winter months. Private insurance was predictive of lower hospitalization costs and LOS as well as lower in-hospital mortality. CONCLUSION: Asthma continues to account for significant in-hospital mortality and resource utilization, especially in mechanically ventilated patients. Age, admissions during winter months and the type of insurance are independent predictors of in-hospital outcomes.

Utilization of catheter-directed thrombolysis in pulmonary embolism and outcome difference between systemic thrombolysis and catheter-directed thrombolysis.

OBJECTIVE: The aim of the study was to assess the utilization of catheter-directed thrombolysis (CDT) and its comparative effectiveness against systemic thrombolysis in acute pulmonary embolism (PE). BACKGROUND: Contemporary real world data regarding utilization and outcomes comparing systemic thrombolysis with CDT for PE is sparse. METHODS: We queried the Nationwide Inpatient Sample from 2010 to 2012 using the ICD-9-CM diagnosis code 415.11, 415.13, and 415.19 for acute PE. We used propensity score analysis to compare outcomes between systemic thrombolysis and CDT. Primary outcome was in-hospital mortality. Secondary outcome was combined in-hospital mortality and intracranial hemorrhage (ICH). RESULTS: Out of 110,731 patients hospitalized with PE, we identified 1,521 patients treated with thrombolysis, of which 1,169 patients received systemic thrombolysis and 352 patients received CDT. After propensity-matched comparison, primary and secondary outcomes were significantly lower in the CDT group compared to systemic thrombolysis (21.81% vs. 13.36%, OR 0.55, 95% CI 0.36-0.85, P value = 0.007) and (22.89% vs. 13.36%, OR 0.52, 95% CI 0.34-0.80, P value = 0.003), respectively. The median length of stay [7 days, interquartile range (IQR) (5-9 days) vs. 7 days, IQR (5-10 days), P = 0.17] was not significant between the two groups. The CDT group had higher cost of hospitalization [$17,218, IQR ($12,272-$23,906) vs. $23,799, IQR ($17,892-$35,338), P < 0.001]. Multivariate analysis identified increasing age, saddle PE, cardiopulmonary arrest, and Medicaid insurance as independent predictors of in-hospital mortality. CONCLUSIONS: CDT was associated with lower in-hospital mortality and combined in-hospital mortality and ICH.

Impact of atrial fibrillation on in-hospital outcomes among hospitalizations for cardiac surgery: an analysis of the National Inpatient Sample.

The short-term impact of atrial fibrillation (AF) on cardiac surgery hospitalizations has been previously reported in cohorts of various sizes, but results have been variable. Using the 2005-2014 National Inpatient Sample, we identified all adult hospitalizations for cardiac surgery using the International Classification of Diseases, Ninth Revision, Clinical Modification as any procedure code and AF as any diagnosis code. We estimated the impact of AF on inpatient mortality, length of stay (LOS), and cost of hospitalization using survey-weighted, multivariable logistic, accelerated failure-time log-normal, and log-transformed linear regressions, respectively. Additionally, we exact-matched AF to non-AF hospitalizations on various confounders for the same outcomes. A total of 1,269,414 hospitalizations were noted for cardiac surgery during the study period. Coexistent AF was found in 44.9% of these hospitalizations. Overall mean age was 65.6 years, 40.9% were female, mean LOS was 11.6 days, and inpatient mortality was 4.5%. Stroke rate was lower in AF hospitalizations (1.8% vs 2.1%, p<0.001). Mortality was lower in the AF (3.9%) versus the non-AF (5%) group (exact-matched OR or emOR=0.48, 95% CI 0.29 to 0.80, p<0.001; 987 matched pairs, n=2423), with similar results after procedural stratification: isolated valve replacement/repair (emOR=0.38, p<0.001), isolated coronary artery bypass graft (CABG) (emOR=0.33, p<0.001), and CABG with valve replacement/repair (emOR=0.55, p<0.001). A 12% increase was seen in LOS in the AF subgroup (exact-matched time ratio=1.12, 95% CI 1.10 to 1.14, p<0.001) among hospitalizations which underwent valve replacement/repair with or without CABG. Hospitalizations for cardiac surgery which had coexistent AF were found to have lower inpatient mortality risk and stroke prevalence but higher LOS and hospitalization costs compared with hospitalizations without AF.

Trends and Outcomes of Atrial Fibrillation-Flutter Hospitalizations Among Heart Transplant Recipients (From the National Inpatient Sample).

Atrial fibrillation-flutter (AF) has been described in 10% to 24% of patients after heart transplant (HT). Data on AF hospitalizations after HT are limited to single-center experiences. To bridge this gap, we performed an analysis of admissions for AF in HT patients from the National Inpatient Sample (NIS) years 2000 to 2014. All hospitalizations with a primary diagnosis of 427.31 or 427.32 and V42.1 were used to identify hospitalizations with AF and previous HT respectively. Among a total of 211,961 HT related hospitalizations, 1,304 (0.62%) (955 males, 349 females, mean age 59 years, median CHA2DS2Vasc score 2 [Interquartile range 1 to 3]) were admitted with a primary diagnosis AF. Most hospitalizations were nonelective (80.17%). In-hospital mortality was 2.3% and the mean length of stay (LOS) was 3.7 days. Among those patients who were discharged from hospital, 85 % were discharged to home with self-care. Most commonly reported secondary diagnoses included hypertension (57.9%), diabetes (33%), renal failure (31.3%), and congestive heart failure (22%). The event rates for ischemic stroke and gastrointestinal bleeding in the same admission with the AF hospitalization were low (1.2% and 1.2% respectively). Cardioversion was performed in 37% and ablation in 11.2% of admissions. The adjusted median cost of hospitalization was $6478.7 (IQR $3561.8 to $12352.3) and did not change significantly during the study period. AF is a relatively infrequent cause of hospitalization among HT recipients. The number of hospitalizations, ablations, cardioversions, disposition, LOS, and cost of hospitalization for AF remained stable during the study period.

Outcomes of patients admitted with ventricular arrhythmias and sudden cardiac death in the United States.

BACKGROUND: Mortality caused by ventricular arrhythmias (VAs) remains a problem of epidemic proportions. Understanding current trends on admission of VA, patient characteristics, morbidity, mortality, and health care utilization could help us improve allocation of health care resources and risk prediction. OBJECTIVE: The purpose of this study was to investigate clinical outcomes of VA, including ventricular tachycardia (VT), implantable cardioverter-defibrillator (ICD) shocks, and sudden cardiac death (SCD); and to identify predictors of morbidity and mortality, patterns of utilization of ICD and VT ablation, and the impact of such metrics on overall health care utilization. METHODS: From 2010-2015, we identified 290,998 VA hospitalizations, which were stratified into group 1: normal heart; group 2: ischemic heart disease (IHD); group 3: nonischemic heart disease (non-IHD); group 4: ICD shocks; and group 5: SCD (cardiac arrest without ICD shock). RESULTS: The number of admissions for VA decreased during the study period (except for patients with SCD and ICD shock, which increased); in-hospital mortality in patients admitted with VA and SCD increased; utilization of VT ablation in patients with ICD shocks and IHD increased; ICD implantation decreased in non-IHD patients and IHD patients; and admission for SCD was the strongest predictor of in-hospital mortality, followed by patients with non-IHD, patients with ICD shocks, and all patients with a Charlson comorbidity index ≥2. CONCLUSION: We report a decrease in admissions for VA, decreased ICD utilization, a change in pattern of VT ablation utilization, and an increase of in-hospital mortality in SCD patients. Predictors of adverse outcomes identified in our study should be considered when developing risk models for patients undergoing risk assessment for SCD.

Impact of atrial fibrillation on outcomes with motor vehicle accidents.

BACKGROUND: We examined the effect of AF a commonly encountered arrhythmia with significant morbidity on mortality following a motor vehicle accident (MVA) related hospitalization. METHODS: The Nationwide Inpatient Sample (NIS) was queried to identify patients with AF (ICD-9 CM 427.31) and MVA (ICD-9 CM E810.0-E819.9), considered separately and together, from 2003 through 2012. Baseline characteristics were identified and multilevel mixed model multivariate analysis was employed to verify the impact of AF on in-patient mortality in survivors. RESULTS: Of an estimated 2,978,630 MVA admissions reported, 79,687 (2.6%) hospitalizations also had a diagnosis of AF. The in-hospital mortality was 2.6% in MVA alone and 7.6% in MVA and AF. In multivariate analysis, after adjustment for age, gender, Charlson Comorbidity Index (CCI), the Trauma Mortality Prediction Model (TMPM), and hospital characteristics, AF was independently associated with in-hospital mortality [Odds ratio (OR) 1.52, confidence interval (CI) 1.41-1.69, P value<0.0001]. In patients with MVA and AF, increasing age, CCI, and TMPM were associated with higher mortality. Female gender is associated with lower mortality (OR 0.84, CI 0.81-0.88, P -0.0016). Most patients with MVA and AF had a CHADS2 score of 2 (34.6%). Mortality and transfusion rates were higher in MVA and AF patients compared to patients with MVA alone across all CHADS2 scores. CONCLUSION: In patients with a MVA, the presence of AF is an independent risk factor for in-hospital mortality.

Trends of Cannabis Use Disorder in the Inpatient: 2002 to 2011.

OBJECTIVES: The nationwide prevalence of cannabis use/abuse has more than doubled from 2002 to 2011. Whether the outpatient trend is reflected in the inpatient setting is unknown. We examined the prevalence and incidence of cannabis abuse/dependence as determined by discharge coding in a 10-year (2002-2011) National Inpatient Sample, as well as various trends among demographics, comorbidities, and hospitalization outcomes. METHODS: Cannabis abuse/dependence was identified on the basis of International Classification of Diseases, 9th Revision, Clinical Modification codes 304.3* and 305.2* in adults aged 18 years or more. We excluded cases coded "in remission." National estimates of trends and matched-regression analyses were conducted. RESULTS: Overall, 2,833,567 (0.91%) admissions with documented cannabis abuse/dependence were identified, patients had a mean age of 35.12 ± 0.06 years, 62% were male, and there was an increasing trend in prevalence from 0.52% to 1.34% (P <.001). The mean Charlson Comorbidity Index was 0.47 ± 0.006, and inpatient mortality was 0.41%. All of the above demonstrated an increasing trend (P <.001). Mean length of stay was 6.23 ± 0.06 days. The top primary discharge diagnoses were schizoaffective/mood disorders, followed by psychotic disorders and alcoholism. Asthma prevalence in nontobacco smokers had a steeper increase in the cannabis subgroup than in the noncannabis subgroup (P = .002). Among acute pancreatitis admissions, cannabis abusers had a shorter length of stay (-11%) and lower hospitalization costs (-7%) than nonabusers. CONCLUSION: Cannabis abuse/dependence is on the rise in the inpatient population, with an increasing trend toward older and sicker patients with increasing rates of moderate to severe disability. Psychiatric disorders and alcoholism are the main associated primary conditions. Cannabis abuse is associated with increased asthma incidence in nontobacco smokers and decreased hospital resource use in acute pancreatitis admissions.

Management of Hypertension in Patients with Aortic Valvular Stenosis.

Aortic stenosis (AS) has an increasing prevalence with age and is commonly associated with hypertension. While it has been established that hypertension is associated with increased mortality in patients with AS, further randomized control trials addressing the use of antihypertensives specifically in patients with AS are needed. The management of hypertension in patients with AS needs a cautious approach due to complex hemodynamic and structural changes involved. Comorbidities like coronary artery disease, heart failure and arrhythmias further dictate management of hypertension in patients with AS. The aim of this article is to review the various agents used in the management of hypertension in patients with AS.

Transcatheter Aortic Valve Replacement Complication Rates in Teaching Vs Non-Teaching Centers in the United States.

OBJECTIVE: The objective of our study is to compare transcatheter aortic valve replacement (TAVR) complication rates among teaching vs non-teaching centers in the United States. METHODS: Using National Inpatient Sample (NIS) data, the largest all-payer database of hospital inpatient stay available in the United States, we identified patients (age ≥18 years) who underwent TAVR from January-December 2012. We constructed multivariable models to determine independent predictors (age, sex, race, Charlson's comorbidity index, hospital size, hospital location, and TAVR approach) of TAVR-associated complications. RESULTS: We identified 7405 TAVR procedures performed in the United States in 2012. In all, 88% of TAVRs were performed in teaching centers. There was no difference in mortality following TAVR between teaching and non-teaching centers. In-hospital complication rate was lower in teaching centers vs non-teaching centers (42% vs. 50%, respectively; P<.001). In adjusted analysis, hemorrhage requiring transfusion (13.2% vs. 20.8%; P<.001), renal complications requiring dialysis (1.2% vs. 2.3%; P<.01), respiratory complications (7.5% vs. 11%; P<.001), and complications requiring open-heart surgery (2% vs. 4.6%; P<.001) were lower in teaching centers vs non-teaching centers. Vascular access-site, pacemaker insertion, pericardial, and neurological complications were similar between teaching and non-teaching centers. CONCLUSION: Institutional design impacts TAVR complications, albeit with no difference in mortality. In general, complication rates are lower in teaching centers compared with non-teaching centers.

What is the optimal approach to a non- culprit stenosis after ST-elevation myocardial infarction - Conservative therapy or upfront revascularization? An updated meta-analysis of randomized trials.

BACKGROUND: Non-culprit percutaneous coronary intervention (PCI) during a ST-segment elevation myocardial infarction (STEMI) remains controversial. We performed a meta-analysis of the published literature comparing a strategy of complete revascularization (CR) with culprit or target vessel revascularization (TVR)-only after STEMI in patients with multi-vessel disease. METHODS: We searched PubMed/Medline, Cochrane, EMBASE, Web of Science, CINAHL, Scopus and Google-scholar databases from inception to March-2016 for clinical trials comparing CR with TVR during PCI for STEMI. Mantel-Haenszel risk ratio (MH-RR) with 95% confidence intervals (CI) for individual outcomes was calculated using random-effects model. RESULTS: A total of 7 randomized trials with 2004 patients were included in the final analysis. Mean follow-up was 25.4months. Major adverse cardiac events (MACE) (MH-RR: 0.58, 95% CI: 0.43-0.78, P<0.001), cardiac deaths (MH-RR: 0.42, 95% CI: 0.24-0.74, P=0.003) and repeat revascularization (MH-RR: 0.36, 95% CI: 0.27-0.48, P<0.001) were much lower in the CR group when compared to TVR. However, there was no significant difference in the risk of all-cause mortality (0.84, 95% CI: 0.57-1.25, P=0.394) or recurrent MI (MH-RR: 0.66, 95% CI: 0.34-1.26, P=0.205) between the two groups. CR appeared to be safe with no significant increase in adverse events including stroke rates (MH-RR: 2.19, 95% CI: 0.59-8.12, P=0.241), contrast induced nephropathy (MH-RR: 0.73, 95% CI: 0.34-1.57, P=0.423) or major bleeding episodes (MH-RR: 0.72, 95% CI: 0.34-1.54, P=0.399). CONCLUSIONS: CR strategy in STEMI patients with multivessel coronary artery disease is associated with reduction in MACE, cardiac mortality and need for repeat revascularization but with no decrease in the risk of subsequent MI or all-cause mortality. CR was safe however, with no increase in adverse events including stroke, stent thrombosis or contrast nephropathy when compared to TVR.

A Review of Hypertension Management in Atrial Fibrillation.

Atrial fibrillation (AF) is one of the commonest arrhythmias in clinical practice and has major healthcare and economic implications. It is a growing epidemic with prevalence all set to double to 12 million by 2050. After adjusting for other associated conditions, hypertension confers a 1.5- and 1.4-fold risk of developing AF, for men and women respectively. Furthermore, in patients with AF, the presence of hypertension has a cumulative effect on the risk of stroke. Growing evidence suggests reversal or attenuation of various structural and functional changes predisposing to AF with the use of antihypertensive medications. Randomized trials have shown major reduction in the risk of stroke and heart failure with blood pressure reduction. However, such trials are lacking in AF patients specifically. The Joint National Committee-8 guidelines have not addressed the threshold or goal BP for patients with known AF. Furthermore, "J-shaped" or "U-shaped" curves have been noted during hypertension management in patients with AF with published data demonstrating worse outcomes in patients with strict BP control to <110/60 mmhg similar to coronary artery disease. In this review, we outline the available literature on management of hypertension in patients with AF as well as the role of individual anti-hypertensive medications in reducing the incidence of AF Fig. 1.
