RESUMEN
BACKGROUND: Heart failure (HF) is a pervasive global health concern, with acute decompensated heart failure (ADHF) contributing significantly to morbidity and mortality. Medications used in patients with HF may exacerbate HF or prolong the QT interval, posing additional risks. OBJECTIVE: The objective is to assess the prevalence and utilization patterns of medications known to cause or exacerbate HF and prolong the QT interval among patients with ADHF. Understanding these patterns is crucial for optimizing patient care and minimizing potential risks. METHODS: A retrospective chart review was conducted at Huntsville Hospital, Huntsville, USA, covering 602 patients with ADHF over a 40-month period. Inclusion criteria involved age ≥ 18 years, a history of HF, and ADHF admission. The 2016 American Heart Association Scientific Statement was used to identify drugs that may cause or exacerbate HF and those that could prolong the QT interval RESULTS: Among the 602 patients, 57.3% received medications causing or exacerbating HF, notably albuterol (34.9%) and diabetes medications (20.4%), primarily metformin, followed by urologic agents (14.3%), mostly tamsulosin, and nonsteroidal anti-inflammatory drugs (NSAIDs) (6.1%). Moreover, 82.9% were on medications prolonging the QT interval, with loop diuretics, amiodarone, ondansetron, and famotidine most prevalent. Furthermore, 42.1% of the patients received more than two concomitant medications that prolong the QT interval, which can further exacerbate the risk of torsades de pointes. CONCLUSION: This study underscores the high prevalence of HF-causing or HF-exacerbating medications and QT-prolonging drugs in patients with ADHF. Healthcare professionals must be cognizant of these patterns, advocating for safer prescribing practices to optimize patient outcomes and reduce the burden of HF-related hospitalizations.
RESUMEN
BACKGROUND: The use of activated prothrombin complex concentrate (aPCC) to treat direct oral anticoagulant (DOAC)-associated bleeding is off-label and clinical experience is limited. OBJECTIVES: We aimed to assess the efficacy and safety of aPCC in reversing the anticoagulant effect of apixaban and rivaroxaban in patients presenting with major bleeding. METHODS: A retrospective cohort study of adult non-randomized patients was conducted at a tertiary referral medical center in the United States (US) to investigate the use of aPCC for the reversal of the anticoagulant effect of apixaban and rivaroxaban in patients presenting with major bleeding. The primary outcome was achieving clinical hemostasis according to prespecified criteria. Safety outcomes included the occurrence of thrombotic events during hospitalization. RESULTS: A total of 217 patients were included in the study. Intracranial hemorrhage (ICH) was the most common site of bleeding (n = 100, 46.1%), followed by gastrointestinal bleed (n = 87, 40.1%). Clinical hemostasis was achieved in 170 patients (78.3%), and the risk of not achieving hemostasis with ICH-related bleeding was significantly higher than that of non-ICH-related bleeding (2.5, 95% confidence interval [CI] 1.44-4.34; p < 0.001). Eight patients not achieving hemostasis died during hospitalization, all of whom were suffering from ICH, and mortality associated with non-ICH-related bleeding was significantly lower compared with ICH-related bleeding (0.91, 95% CI 0.86-0.97; p < 0.001). Thromboembolic events during hospitalization occurred in one patient (0.5%). CONCLUSIONS: The use of aPCC for the management of apixaban- or rivaroxaban-related major bleeding is effective in most cases and is associated with a low risk of thromboembolism.

Data on the use of activated prothrombin complex concentrate (aPCC) for the management of warfarin associated major bleeding is sparse. The objective of the study was to assess the achievement of effective clinical hemostasis using aPCC in patients presenting with major bleeding while on warfarin. We also assessed the safety of the drug. This retrospective study was conducted at a tertiary care teaching center in the USA where patients with major bleeding while receiving warfarin, and received aPCC were included. Efficacy of aPCC in achieving effective hemostasis was assessed according to the International Society of Thrombosis and Hemostasis Scientific and Standardization Subcommittee criteria. Efficacy was also assessed by achieving INR < 1.5 after treatment. The primary safety endpoint was the occurrence of any thromboembolic complications. A total of 67 patients were included in the study. The most common site for bleeding was intracerebral hemorrhage (n = 37, 55.2%), followed by gastrointestinal bleed (n = 26, 38.8%). Clinical hemostasis was achieved in 46 (68.7%) patients and of the 21 (31.3%) patients who did not achieve clinical hemostasis, 16 died. Thirty nine (58.2%) patients achieved INR < 1.5. Five (7.5%) patients developed thromboembolic complications. This study suggests that the use of aPCCs is effective in achieving effective hemostasis in patients on warfarin presenting with major bleeding.

BACKGROUND: Polypharmacy continues to be a topic of concern among older adults and puts patients at increased risk of potential drug-drug interactions (DDIs) and negative health outcomes. The objective of this study was to assess the prevalence of polypharmacy among older adults with cardiovascular disease (CVD) and to identify severe potential DDIs. METHODS: A retrospective chart review was conducted in a tertiary care center over a three-month period where we reviewed home medications of older adults upon hospital admission. Inclusion criteria were age ≥ 65 years, history of CVD, and admission to the cardiology service. Polypharmacy was defined as 5 or more medications taken concomitantly, hyper-polypharmacy was defined as 10 or more medications taken concomitantly, and severe potential DDIs were considered to be those belonging to category D or X using Lexicomp® Drug Information Handbook. Category D interaction states that modification of therapy should be considered while category X states that the combination should be absolutely avoided. RESULTS: A total of 404 patients with a mean age of 76.6 ± 7.4 years were included. Patients were taking an average of 11.6 ± 4.5 medications at home and 385 (95%) received polypharmacy, 278 (69%) received hyper-polypharmacy, and 313 (77.5%) had at least one severe potential DDI. Under category D, the most common potential DDIs were drugs with additive central nervous system (CNS) depressant effect and drugs that increase the risk of QT prolongation. Under category X, the most common potential DDIs were non-selective ß-blockers that may diminish the bronchodilator effect of ß2 agonists and drugs with anticholinergic properties that enhance the ulcerogenic effect of oral solid potassium. CONCLUSIONS: Polypharmacy, hyper-polypharmacy, and severe potential DDIs are very common in older adults with CVD. Clinicians should vigilantly review patients' drug records and adjust therapy accordingly to prevent adverse drug reactions and negative health outcomes.

BACKGROUND: Clinical experience with using activated prothrombin complex concentrates (aPCCs) to reverse the effects of factor Xa inhibitors is limited. OBJECTIVES: Our objective was to assess the achievement of effective clinical hemostasis using aPCC in patients on chronic apixaban or rivaroxaban therapy presenting with major bleeding in whom a reversal agent is warranted. We also assessed the safety of the drug. METHODS: A retrospective medical records review was conducted at a tertiary referral medical center in the USA. Patients presenting with major bleeding while receiving apixaban or rivaroxaban and treated with aPCC were included. Clinical hemostasis was assessed using International Society of Thrombosis and Hemostasis Scientific and Standardization Subcommittee criteria. RESULTS: A total of 35 patients were included in the study. The most common site of bleeding was intracerebral hemorrhage (ICH) (n = 18 [51.4%]), followed by gastrointestinal bleed (n = 10 [28.6%]). Clinical hemostasis was achieved in 24 (68.6%) patients; 11 patients (31.4%) did not achieve clinical hemostasis; nine of these patients had ICH. Seven of the patients who did not achieve hemostasis died during hospitalization. Three (8.6%) patients experienced thromboembolic events during hospitalization. In total, 21 (60%) patients were receiving concomitant medications that interact with anti-factor Xa inhibitors and can increase the risk of bleeding. CONCLUSIONS: Our study suggests that aPCC could be an option in patients with major bleeding associated with apixaban or rivaroxaban. It may be an alternative for patients who need anticoagulation reversal if the specific antidote, andexanet alfa, is unavailable.

PURPOSE: A case report of dabigatran-associated coagulopathy that lasted for about 1 week after drug discontinuation despite use of several treatment measures is presented. SUMMARY: Life-threatening hemorrhage can occur in patients receiving dabigatran, a direct-acting oral anticoagulant. Idarucizumab is a newly approved dabigatran antidote that neutralizes the drug's anticoagulant activity. An 80-year-old Caucasian man with a medical history of hypertension, coronary artery disease, congestive heart failure, gout, and atrial fibrillation was hospitalized with acute kidney injury (AKI) caused by bilateral hydronephrosis secondary to distal urethral stricture. The patient had prolonged coagulation parameters and major bleeding. Initial laboratory values revealed anemia, with a hemoglobin concentration of 8.9 g/dL; a serum creatinine concentration of 3.9 mg/dL; a prothrombin time of 15 seconds; an International Normalized Ratio of 1.1; and a platelet count of 142,000 platelets/mm3. Three hemodialysis sessions and administration of fresh frozen plasma (FFP), packed red blood cells, and 2 doses of idarucizumab were required in order to achieve hemostasis 8 days after dabigatran was discontinued. CONCLUSION: A patient with AKI who had been taking dabigatran and developed major bleeding needed 2 doses of idarucizumab in addition to FFP and 3 sessions of hemodialysis in order for hemostasis to be restored. This case suggests that idarucizumab might not produce hemostasis in a timely manner in patients with poor renal function.

BACKGROUND: Idarucizumab is used to reverse the effects of dabigatran. Information on the use of idarucizumab in the clinical setting remains very limited. OBJECTIVE: The objective of this study was to describe clinical experience with idarucizumab in a large medical teaching center in the USA. METHODS: Patients who received idarucizumab to reverse the effects of dabigatran between 1 January 2016 and 30 June 2018 were studied. In patients with major bleeding, the efficacy of idarucizumab was assessed using criteria of the International Society of Thrombosis and Hemostasis Scientific and Standardization Subcommittee. The course of treatment and clinical outcomes in patients who received idarucizumab for emergency surgery or procedures are described. RESULTS: In total, 13 patients received idarucizumab for atrial fibrillation during the study period. Their mean age was 77.5 ± 7.1 years, and 12 (92.3%) were men. Idarucizumab was used in 11 patients for major bleeding events and in two patients for emergency surgery or procedures. Intracranial hemorrhage (n = 6) and gastrointestinal bleed (n = 2) were the most common types of bleeding. Clinical hemostasis was achieved in 8 of 11 (72.7%) patients with major bleeding. One patient with acute kidney injury needed two doses of the reversal agent to achieve hemostasis. One patient underwent open heart surgery and developed postoperative hemorrhage despite receiving idarucizumab. None of the patients experienced thrombotic complications or side effects that could be attributed to idarucizumab. CONCLUSION: Real-world experience in a US hospital with the use of idarucizumab in emergency situations requiring the reversal of the effects of dabigatran is described. Idarucizumab represents an exciting new antidote for dabigatran, but clinical efficacy and cost-effectiveness data remain lacking.

BACKGROUND: Non-vitamin K oral anticoagulants (NOACs) have emerged as an attractive alternative to vitamin K antagonists for various thromboembolic indications. However, prescribed NOAC doses are often inconsistent with drug labeling and prescribers might not consider the potential risks associated with concomitant use of other drugs, which can compromise NOACs' safety and effectiveness. METHODS: A retrospective chart review was conducted in a tertiary care center in USA over a 4-month period. We studied patients whose home medications included NOACs and assessed the appropriateness as per drug labeling, taking into consideration relevant clinical factors and concomitant drug intake. RESULTS: A total of 909 patients with a mean age of 70.6 ± 13.1 years, out of which 51.6% were males, were included. The majority of patients received NOACs for stroke prevention in atrial fibrillation (AF) (70.5%), or deep venous thrombosis/pulmonary embolism (DVT/PE) treatment (13.5%). The most common drug prescribed was apixaban (57.8%) followed by rivaroxaban (34.0%), and less frequently dabigatran (7.7%). Inappropriate dosing was significantly more frequent among older patients, those taking NOACs for AF, those taking a higher number of home medications, and those with a lower creatinine clearance. Seven hundred and six patients (77.67%) had at least one drug-NOAC interaction, out of which 515 were rated major interactions. Antiplatelets, amiodarone, non-steroidal anti-inflammatory medications, and calcium channel blockers were the most commonly interacting drugs. CONCLUSION: A significant number of patients received NOACs at doses inconsistent with the package labeling or had clinically significant drug-drug interactions with NOACs. Efforts are warranted to improve appropriate dosing and avoid significant drug interactions.

There is limited clinical experience with the use of coagulation concentrates to reverse the effect of direct oral anticoagulants. We assess the achievement of effective clinical hemostasis with the use of 4-factor prothrombin complex concentrate (PCC) in patients on apixaban or rivaroxaban presenting with major bleeding. A retrospective chart review was conducted at a tertiary referral medical center in the USA. We assess the achievement of clinical hemostasis using 4-factor PCC in patients on chronic apixaban or rivaroxaban therapy presenting with major bleeding. Clinical hemostasis was assessed by the International Society of Thrombosis and Hemostasis Scientific and Standardization Subcommittee criteria. A total of 29 patients are included in the study. The most common site of bleeding was intracranial hemorrhage (ICH) (72.4%), followed by gastrointestinal bleed (13.8%). Clinical hemostasis was achieved in 21 (72.4%) patients. Patients who did not achieve clinical hemostasis (27.6%) suffered from ICH, and all of them died during hospitalization except for two patients who were discharged with neurologic deterioration. One patient developed multiple brain infarctions after receiving 4-factor PCC. Sixteen patients (55.2%) were receiving concomitant medications that interact with apixaban and rivaroxaban and increase the risk of bleeding. Four-factor PCC appears to be effective in achieving clinical hemostasis in patients on apixaban or rivaroxaban presenting with major bleeding. It may be an alternative to patients who need anticoagulation reversal if the specific antidote, andexanet alfa, is not available.

BACKGROUND: In recent years there has been a substantial increase in the use of over-the-counter (OTC) products around the world. While they are assumed to be safe by consumers, they can potentially lead to adverse effects and drug interactions particularly in older adults. METHODS: We assessed the patterns of OTC products used by older adults admitted to the cardiology service in a tertiary care medical center in the USA over a three month period. We conducted a retrospective chart review where older adults with cardiovascular diseases (CVD) who were taking at least one OTC product at home were included. RESULTS: Out of 404 patients who were admitted to the cardiology service, 281 (69.6%) were taking OTC products. Patients were taking a total of 659 OTC products; mean of 2.35 ± 1.57 and the range varied from 1 to 9 products. The most commonly used products were vitamins (37.3%), followed by laxatives (17%), minerals (13.6%), stomach acid reducers (9%), and analgesics (3.6%). OTC users were found to be suffering from more comorbidities and received more prescription medications as compared to non-users. Gender and age did not have an impact on the use of OTC products while patients with atrial fibrillation, sleep apnea and gastro-esophageal reflux disease were more likely to use OTC products. CONCLUSION: Use of OTC products is quite frequent in older adults with CVD in our study. Clinicians should ask about OTC product usage and counsel patients about the risks and benefits associated with their use.

BACKGROUND: Pain is common in older adults and clinicians are often faced by many challenges when selecting appropriate treatment due to age-related changes in pharmacokinetics, pharmacodynamics, increased comorbidities, and polypharmacy. METHODS: This study assessed the patterns of pain medications used at home among older adults admitted to the cardiology service in a tertiary care teaching center in the US from March to May 2016. A retrospective chart review was conducted where adults, 65 years of age or older, with cardiovascular diseases admitted to the cardiology service and taking at least one pain medication at home were studied. RESULTS: Out of 404 patients who were admitted to the cardiology service, 228 (56.4%) were on at least one pain medication. Among the admitted patients, 64.2% of the females received at least one pain medication, as compared to 49% of the males (p = 0.002). Participants had a mean age of 76.34 ± 7.43 years, and received a mean of 1.81 ± 0.83 pain medications. Neuropathic pain was the most common indication (33.4%), followed by arthritis (17.5%), and cancer (15.8%). The most commonly used pain medications were gabapentin/pregabalin 79 (34.6%), acetaminophen plus an opiate 78 (34.2%), opiates 56 (24.6%), tramadol 36 (15.8%), followed by non-selective NSAIDs 21 (9.2%). Twelve (5.3%) patients received duplication of pain medications, while 14 (5.7%) received an inappropriate combination of pain medications. Twenty-three patients (10.1%) received muscle relaxants in conjunction with pain medications, 20 of which are considered poorly tolerated by older adults. CONCLUSION: This stufy described the patterns of use of pain medications among older adults with cardiovascular disease. Careful selection of appropriate pain medications based on different clinical parameters is very essential to avoid prescribing inappropriate therapy that can lead to patient harm.

BACKGROUND: The use of potentially inappropriate medications (PIMs) may pose more risks than benefits to patients and is a major factor contributing to the likelihood of serious adverse drug reactions and negative health outcomes among older patients. METHODS: A retrospective chart review was conducted in a tertiary care center in USA where home medications of the older patients were reviewed and analyzed upon hospital admission over three months, from March till May 2016. Inclusion criteria were age of 65 years and above, history of cardiovascular disease, and admission to the cardiology service. The aim of our study was to determine the frequency and factors associated with PIMs, by applying the updated Beers 2015 criteria. RESULTS: A total of 404 patients were included in the study and were taking a total of 4669 medications at home, an average of 11.6 ± 4.5 medications per patient. The proportion of PIMS was 20% of all medications reported, with an average of 2.4 PIM per patient, and 87.4% of patients were receiving at least one PIM. Significant association was found between use of PIMs and number of home medications, female gender, and number and types of comorbidities. Comorbidities associated with more PIMs were heart failure, atrial fibrillation/flutter, history of falls/fractures, cerebrovascular accident, and depression. The most commonly prescribed PIMs were: drugs that may exacerbate or cause syndrome of inappropriate antidiuretic hormone secretion or hyponatremia (29.7%), scheduled use of proton pump inhibitors (PPIs) > 8 weeks in non-high-risk patients (11.3%), and benzodiazepines (8.1%). CONCLUSIONS: A high prevalence of PIMs in older patients with cardiovascular disease was observed. Provider education and detailed assessment of medication lists upon hospital admission by multidisciplinary teams can help in preventing the use of PIMs.

This study assessed the profile of benzodiazepine (BDZ) users in Lebanon. Adult patients visiting the pharmacies with prescriptions of BDZs were included in the study. Seven hundred and eighty-six current BDZ users were included, of whom 54.2% were females. Twenty-three percent reported being alcohol consumers and were mostly males. The two most commonly used BDZs were alprazolam (34.6%) and bromazepam (33.6%). The indication for use was mainly anxiety (44.4%), insomnia (22.5%), and depression (15.9%). The prescribing physicians were primarily psychiatrists (43.2%), followed by general practitioners (29.7%). Forty percent had been taking the drug for more than a year. Among those using BDZs for at least 1 month, 35.5% increased the dose with time. Thirty-three percent reported having experienced side effects. Eighteen patients (2.3%) reported taking more than one BDZ concomitantly, while 18.3% were taking drugs that should not be prescribed along with BDZs. In conclusion, the use of BDZs is highest among females, especially for the treatment of anxiety. Moreover, continuous use of the drugs for more than a year as well as significant potential drug interactions was identified.
RESUMEN
OBJECTIVE: We examined the potential effect of sex and age on warfarin dosing in ambulatory adult patients. METHODS: We conducted a retrospective chart review of patients attending an anticoagulation clinic. We included patients anticoagulated with warfarin for atrial fibrillation or venous thromboembolism who had a therapeutic international normalized ratio of 2-3 for 2 consecutive months. We excluded patients who had been on any drug that is known to have a major interaction with warfarin, smokers, and heavy alcohol consumers. Out of 340 screened medical records, 96 met the predetermined inclusion criteria. The primary outcome assessed was warfarin total weekly dose (TWD). RESULTS: There was a statistically significant difference in the TWD among the ages (P<0.01); older patients required lower doses. However there was no statistically significant difference in the TWD between sexes (P=0.281). CONCLUSION: Age was found to have a significant effect on warfarin dosing. Even though women did require a lower TWD than men, this observation was not statistically significant.
RESUMEN
Drug-induced autoimmune hemolytic anemia is a rare condition. We report the case of a 32-year-old white female who presented to the emergency department with generalized fatigue, fever, and jaundice. The patient reported using levofloxacin few days prior to presentation for urinary tract infection. The patient had evidence of hemolytic anemia with a hemoglobin of 6.7 g/dL which dropped to 5 g/dL on day 2, the direct Coombs test was positive, indirect bilirubin was 5.5 mg/dL, and LDH was 1283 IU/L. Further testing ruled out autoimmune disease, lymphoma, and leukemia as etiologies for the patient's hemolytic anemia. Levofloxacin was immediately stopped with a gradual hematologic recovery within few days.
RESUMEN
BACKGROUND: Coronary artery disease (CAD) is the major leading cause of death worldwide. The national practice guidelines from the American College of Cardiology (ACC) and American Heart Association (AHA) promote the use of several medical therapies for secondary prevention for patients with CAD. The purpose of this study was to evaluate whether ACS patients, admitted into two tertiary referral medical centers in Beirut, Lebanon, are discharged on optimal medical therapy based on the current AHA/ACC guidelines. METHODS: We reviewed the medical records of all patients with ACS who were admitted to the coronary care units (CCU) of two hospitals in Beirut, Lebanon between May and August 2012. Discharge prescriptions were reviewed and rating for the appropriateness of discharge cardiac medications was based on the AHA/ACC guidelines. We assessed whether patients were discharged on antiplatelet therapy, ß-blockers, angiotensin converting enzymes inhibitors (ACEIs) or angiotensin receptor blockers (ARBs), statins, and nitrates, unless contraindicated or not tolerated. In addition, we assessed whether patients and/or their caregivers were counseled about their disease(s) and discharge medications. RESULTS: 186 patients with a mean age of 63 ± 11.78 years, 70.4% of which were males, were admitted with ACS and were included in the study. Fifty three (28.5%) patients had ST elevation MI (STEMI), 64 (34.4%) had non-ST-elevation myocardial infarction (NSTEMI) and 69 (37.1%) had unstable angina (USA). Sixty two patients (33.3%) were treated with medical therapy and 124 patients (66.7%) underwent percutaneous coronary intervention (PCI). Among eligible patients, 98.9% were discharged on aspirin, 89.1% on dual antiplatelet therapy (aspirin + thienopyridine or ticagrelor), 90.5% on a ß-blocker, 81.9% on an ACEI or ARB, 89.8% on a statin, and 19.4% on nitroglycerin. Overall, 62.9% of the patients received the optimal cardiovascular drug therapy (the combination of dual antiplatelet therapy, a ß-blocker, an ACEIs or an ARB, and a statin), 55.1% were counseled on their disease state(s) and drug therapy, and 92.2% and 55.9% were counseled on smoking cessation and life style changes, respectively. CONCLUSION: In patients admitted with ACS, discharge cardiac medications are prescribed at suboptimal rates. Education of healthcare providers and implementation of ACS discharge protocols may help improve compliance with ACC/AHA guidelines. In addition, clinicians should be encouraged to provide adequate patient counseling.
