Multizonal observational study conducted by clinical practitioners on evolocumab use in subjects with hyperlipidemia in Saudi Arabia and Kuwait: Results from the ZERBINI study.

OBJECTIVES: Dyslipidemia is a prevalent condition with significant morbidity and mortality across the world, including in the Arabian Gulf. The present study aimed to describe the characteristics of patients receiving evolocumab in clinical practice. METHODS: ZERBINI was a multi-country, observational, retrospective/prospective study of subjects receiving evolocumab as part of routine clinical management of their hyperlipidemia. This regional publication reports on adult participants from Saudi Arabia and Kuwait who have had ≥1 dose of evolocumab before enrollment and ≤6 months' prior exposure to evolocumab. Patient characteristics and treatment persistence data were collected in addition to baseline and follow-up data up to 12 months post-evolocumab initiation. RESULTS: Overall, 225 patients were included from two sites, Saudi Arabia (N = 155) and Kuwait (N = 70). Mean age was comparable across sites and most patients had baseline coronary artery disease and/or hypertension. Baseline LDL-C levels (mean ± SD 3.6 ± 1.4 mmol/L in Saudi Arabia, 3.1 ± 1.4 mmol/L in Kuwait) were reduced by approximately 57%-62% in the first 6 months after evolocumab initiation (1.5 ± 1.2 mmol/L in Saudi Arabia [n = 63], 1.2 ± 0.8 mmol/L in Kuwait [n = 28]). This decrease was maintained over the 12-month follow-up period. Most patients achieved ACC 2018 LDL-C goals (<1.8 mmol/L; 74.6% in Saudi Arabia, 93.1% in Kuwait) and ESC 2019 LDL-C goals (<1.4 mmol/L; 66.7% in Saudi Arabia, 75.9% in Kuwait) in the first 6 months after evolocumab initiation. Medication persistence with evolocumab was high (up to 90.7%). Evolocumab had a favorable safety profile and no treatment-emergent adverse events were observed at either site. CONCLUSION: Evolocumab is an effective lipid-lowering treatment in local populations. LDL-C goal achievement is increased when evolocumab is added to background lipid-lowering therapy with high tolerability and persistence. Long-term follow-up and large-scale data are needed to further support these observations.

Optical wireless communication performance enhancement using Hamming coding and an efficient adaptive equalizer with a deep-learning-based quality assessment.

Optical wireless communication (OWC) technology is one of several alternative technologies for addressing the radio frequency limitations for applications in both indoor and outdoor architectures. Indoor optical wireless systems suffer from noise and intersymbol interference (ISI). These degradations are produced by the wireless channel multipath effect, which causes data rate limitation and hence overall system performance degradation. On the other hand, outdoor OWC suffers from several physical impairments that affect transmission quality. Channel coding can play a vital role in the performance enhancement of OWC systems to ensure that data transmission is robust against channel impairments. In this paper, an efficient framework for OWC in developing African countries is introduced. It is suitable for OWC in both indoor and outdoor environments. The outdoor scenario will be suitable to wild areas in Africa. A detailed study of the system stages is presented to guarantee the suitable modulation, coding, equalization, and quality assessment scenarios for the OWC process, especially for tasks such as image and video communication. Hamming and low-density parity check coding techniques are utilized with an asymmetrically clipped DC-offset optical orthogonal frequency-division multiplexing (ADO-OFDM) scenario. The performance versus the complexity of both utilized techniques for channel coding is studied, and both coding techniques are compared at different coding rates. Another task studied in this paper is how to perform efficient adaptive channel estimation and hence equalization on the OWC systems to combat the effect of ISI. The proposed schemes for this task are based on the adaptive recursive least-squares (RLS) and the adaptive least mean squares (LMS) algorithms with activity detection guidance and tap decoupling techniques at the receiver side. These adaptive channel estimators are compared with the adaptive estimators based on the standard LMS and RLS algorithms. Moreover, this paper presents a new scenario for quality assessment of optical communication systems based on the regular transmission of images over the system and quality evaluation of these images at the receiver based on a trained convolutional neural network. The proposed OWC framework is very useful for developing countries in Africa due to its simplicity of implementation with high performance.

The Prognostic Impact of Pulse Pressure in Acute Heart Failure: Insights from the HEARTS Registry.

BACKGROUND: Low pulse pressure predicts long-term mortality in chronic heart failure, but its prognostic value in acute heart failure is less understood. The present study was designed to examine the prognostic value of pulse pressure in acute heart failure. METHODS: Pulse pressure was tested for its impact on short- and long-term mortality in all patients admitted with acute heart failure from October 2009 to December 2010 in eighteen tertiary centers in Saudi Arabia (n = 2609). All comparisons were based on the median value (50 mmHg). Heart failure with reduced ejection fraction was defined as less than 40%. RESULTS: Low pulse pressure was associated with increased short-term mortality in the overall population (OR = 1.61; 95 CI 1.17, 2.22; P 0.004 and OR = 1.51; 95% CI 1.13, 2.01; P = 0.005, for hospital and thirty-day mortality, respectively), and short-term and two-year mortality in the reduced ejection fraction group (OR = 1.81; 95% CI 1.19, 2.74; P = 0.005, OR = 1.69; 95% CI 1.17, 2.45; P = 0.006, and OR = 1.29; 95% CI 1.02, 1.61; P = 0.030 for hospital, thirty-day, and two-year mortality, respectively). This effect remained after adjustment for relevant clinical variables; however, pulse pressure lost its predictive power both for short-term and long-term mortality after the incorporation of systolic blood pressure in the model. Conversely, low pulse pressure was an independent predictor of improved survival at two and three years in heart failure with preserved ejection fraction (OR = 0.43; 95% CI 0.24, 0.78, P = 0.005 and OR = 0.49; 95% CI 0.28, 0.88; P = 0.016, respectively). CONCLUSION: In acute heart failure with reduced ejection fraction, the prognostic value of low pulse pressure was dependent on systolic blood pressure. However, it inversely correlated with long-term survival in heart failure with preserved ejection fraction.

Intraoral Dual Wavelength Laser Diode Therapy for Chronic Maxillary Sinusitis.

BACKGROUND: Chronic sinusitis is one of the most common chronic diseases involving different age groups. The different etiological factors and difficult diagnostic procedures contribute to misdiagnosis and chronicity of sinusitis. There is no standard treatment for sinusitis. Long term use of corticosteroids and antibiotics may lead to numerous adverse side effects. Laser therapy has been suggested as a non-invasive treatment for sinusitis. It has anti-inflammatory and antibacterial effects. When considering maxillary sinusitis, discharge tends to collect in the sinus base due to its anatomy and altered physiology. To improve penetration of laser into the maxillary sinus, intraoral laser at the vestibule depth of the maxilla may be more effective. MATERIAL AND SUBJECT: Thirty-four patients with chronic maxillary sinusitis were assigned into two groups. All were assessed before and after treatment. Group A received laser radiation plus standard medical treatment and group B received medical treatment only. The treatment plan was performed in 12 sessions using a Diode laser with a wavelength of 810 nm and 980nm. The SNOT-22 questionnaire and Computed Tomography were used to evaluate patients. A p-value < 0.05 was considered statistically significant. RESULTS: Both groups showed a significant improvement in symptoms following treatment (p < .001), however, the laser therapy group demonstrated greater improvements for all variables in response to treatment as compared to the traditional treatment group (p < .001). CONCLUSIONS: Using high intensity intra-oral laser therapy with medical treatment is more effective than using medical treatment only for treatment of chronic maxillary sinusitis.

The first survey of the Saudi Acute Myocardial Infarction Registry Program: Main results and long-term outcomes (STARS-1 Program).

BACKGROUND: Prior acute coronary syndrome (ACS) registries in Saudi Arabia might not have accurately described the true demographics and cardiac care of patients with ACS. We aimed to evaluate the clinical characteristics, management, and outcomes of a representative sample of patients with acute myocardial infarction (AMI) in Saudi Arabia. METHODS: We conducted a 1-month snap-shot, prospective, multi-center registry study in 50 hospitals from various health care sectors in Saudi Arabia. We followed patients for 1 month and 1 year after hospital discharge. Patients with AMI included those with or without ST-segment elevation (STEMI or NSTEMI, respectively). This program survey will be repeated every 5 years. RESULTS: Between May 2015 and January 2017, we enrolled 2233 patients with ACS (mean age was 56 [standard deviation = 13] years; 55.6% were Saudi citizens, 85.7% were men, and 65.9% had STEMI). Coronary artery disease risk factors were high; 52.7% had diabetes mellitus and 51.2% had hypertension. Emergency Medical Services (EMS) was utilized in only 5.2% of cases. Revascularization for patients with STEMI included thrombolytic therapy (29%), primary percutaneous coronary intervention (PCI); (42.5%), neither (29%), or a pharmaco-invasive approach (3%). Non-Saudis with STEMI were less likely to undergo primary PCI compared to Saudis (35.8% vs. 48.7%; respectively, p <0.001), and women were less likely than men to achieve a door-to-balloon time of <90 min (42% vs. 65%; respectively, p = 0.003). Around half of the patients with NSTEMI did not undergo a coronary angiogram. All-cause mortality rates were 4%, 5.8%, and 8.1%, in-hospital, at 1 month, and at 1 year, respectively. These rates were significantly higher in women than in men. CONCLUSIONS: There is an urgent need for primary prevention programs, improving the EMS infrastructure and utilization, and establishing organized ACS network programs. AMI care needs further improvement, particularly for women and non-Saudis.

The prognostic impact of hyperglycemia on clinical outcomes of acute heart failure: Insights from the heart function assessment registry trial in Saudi Arabia.

BACKGROUND: The prognostic impact of hyperglycemia (HG) in acute heart failure (AHF) is controversial. Our aim is to examine the impact of HG on short- and long-term survival in AHF patients. METHODS: Data from the Heart Function Assessment Registry Trial in Saudi Arabia (HEARTS) for patients who had available random blood sugar (RBS) were analyzed. The enrollment period was from October 2009 to December 2010. Comparisons were performed according to the RBS levels on admission as either <11.1 mmol/L or ≥11.1 mmol/L. Primary outcomes were hospital adverse events and short- and long-term mortality rates. RESULTS: A total of 2511 patients were analyzed. Of those, 728 (29%) had HG. Compared to non-HG patients, hyperglycemics had higher rates of hospital, 30-day, and 1-year mortality rates (8.8% vs. 5.6%; p = 0.003, 10.4% vs. 7.2%; p = 0.007, and 21.8% vs. 18.4%; p = 0.04, respectively). There were no differences between the two groups in 2- or 3-year mortality rates. After adjustment for relevant confounders, HG remained an independent predictor for hospital and 30-day mortality [odds ratio (OR) = 1.6; 95% confidence interval (CI) 1.07-2.42; p = 0.021, and OR = 1.55; 95% CI 1.07-2.25; p = 0.02, respectively]. CONCLUSION: HG on admission is independently associated with hospital and short-term mortality in AHF patients. Future research should focus on examining the impact of tight glycemic control on outcomes of AHF patients.

Atrial Fibrillation in Patients Hospitalized With Heart Failure: Patient Characteristics and Outcomes From the HEARTS Registry.

Effect of atrial fibrillation (AF) on short- and long-term outcomes in heart failure (HF) is controversial. Accordingly, we examined this relationship in a national multicenter project using data from the Hearts Function Assessment Registry Trial in Saudi Arabia that studied the clinical features and outcomes of patients admitted with de novo and acute on chronic HF. Out of 2593 patients with HF, 449 (17.8%) had AF at presentation. Patients with AF were more likely to be males and older (mean age 65.2 ± 15.0 vs 60.5 ± 14.8 years) to have a history of ventricular tachycardia/ventricular fibrillation (3.1% vs 1.9%) or cerebrovascular accident (15.0% vs 8.5%). However, they were less likely to have diabetes (66.0% vs 55.9%) or coronary artery disease (55.6% vs 42.3%). The 1-, 2-, and 3-year crude mortality rates were significantly higher in patients with AF (23.2% vs 18.3%, 27.4% vs 22.3%, and 27.8% vs 23.2%, respectively). However, there was no significant difference in mortality after adjusting for covariates. Thus, in patients admitted with HF, AF upon presentation was not associated with increased mortality.

Worsening heart failure in 'real-world' clinical practice: predictors and prognostic impact.

AIMS: The aim of this study was to compare the clinical features, predictors, and clinical outcomes of patients hospitalized with acute heart failure (AHF), with and without worsening heart failure (WHF). METHODS AND RESULTS: We used data from a multicentre prospective registry of AHF patients created in Saudi Arabia. WHF was defined as recurrence of heart failure symptoms or signs-with or without cardiogenic shock. In-hospital short- and long-term outcomes, as well as predictors of WHF are described. Of the 2609 AHF patients enrolled, 33.8% developed WHF. WHF patients were more likely to have a history of heart failure and ischaemic heart disease. Use of intravenous vasodilators, inotropic agents, furosemide infusions, and discharge beta-blockers was significantly higher in WHF patients, while use of discharge ACE inhibitors was higher in patients without WHF. Length of hospital stay was significantly longer for WHF patients than for those without WHF [median (interquartile range) 13 (14) vs. 7 (7) days, P < 0.001]. In-hospital, 30-day, 1-year, and 2-year mortality rates were higher in WHF patients than in non-WHF patients. The adjusted odds ratios for in-hospital, 30-day, and 1-year mortality were 4.13 [95% confidence interval (CI) 2.74-6.20, P < 0.001], 3.17 (95% CI 2.21-4.56, P < 0.001), and 1.34 (95% CI 1.04-1.71, P = 0.021), respectively. The strongest predictors for WHF were having ischaemic cardiomyopathy, AHF with concomitant acute coronary syndrome, and low haemoglobin. CONCLUSION: In real-world clinical practice, WHF during hospitalization for AHF is a strong predictor for short- and intermediate-term mortality, and a cause for longer hospital stays.

Acute heart failure with and without acute coronary syndrome: clinical correlates and prognostic impact (From the HEARTS registry).

BACKGROUND: Little is know about the outcomes of acute heart failure (AHF) with acute coronary syndrome (ACS-AHF), compared to those without ACS (NACS-AHF). METHODS: We conducted a prospective registry of AHF patients involving 18 hospitals in Saudi Arabia between October 2009 and December 2010. In this sub-study, we compared the clinical correlates, management and hospital course, as well as short, and long-term outcomes between AHF patients with and without ACS. RESULTS: Of the 2609 AHF patients enrolled, 27.8 % presented with ACS. Compared to NACS-AHF patients, ACS-AHF patients were more likely to be old males (Mean age = 62.7 vs. 60.8 years, p = 0.003, and 73.8 % vs. 62.7 %, p < 0.001, respectively), and to present with De-novo heart failure (56.6 % vs. 28.1 %, p < 0.001). Additionally they were more likely to have history of ischemic heart disease, diabetes, dyslipidemia, and less likely to have chronic kidney disease (p < 0.001 for all comparisons). The prevalence of severe LV systolic dysfunction (EF < 30 %) was higher in ACS-AHF patients. During hospital stay, ACS-AHF patients were more likely to develop shock (p < 0.001), recurrent heart failure (p = 0.02) and needed more mechanical ventilation (p < 0.001). ß blockers and Angiotensin Converting Enzyme inhibitors were used more often in ACS-AHF patients (p = 0.001 and, p = 0.004 respectively). ACS- AHF patients underwent more coronary angiography and had higher prevalence of multi-vessel coronary artery disease (p < 0.001 for all comparisons). The unadjusted hospital and one-month mortality were higher in ACS-AHF patients (OR = 1.6 (1.2-2.2), p = 0.003 and 1.4 (1.0-1.9), p = 0.026 respectively). A significant interaction existed between the level of left ventricular ejection fraction and ACS-AHF status. After adjustment, ACS-AHF status was only significantly associated with hospital mortality (OR = 1.6 (1.1-2.4), p = 0.019). The three-years survival following hospital discharge was not different between the two groups. CONCLUSION: AHF patients presenting with ACS had worse hospital prognosis, and an equivalent long-term survival compared to AHF patients without ACS. These findings underscore the importance of timely recognition and management of AHF patients with concomitant ACS given their distinct presentation and underlying pathophysiology compared to other AHF patients.

Sex Differences in Patients With Acute Decompensated Heart Failure: Insights From the Heart Function Assessment Registry Trial in Saudi Arabia.

We assessed sex-specific differences in clinical features and outcomes of patients with acute heart failure (AHF). The Heart function Assessment Registry Trial in Saudi Arabia (HEARTS), a prospective registry, enrolled 2609 patients with AHF (34.2% women) between 2009 and 2010. Women were older and more likely to have risk factors for atherosclerosis, history of heart failure (HF), and rheumatic heart and valve disease. Ischemic heart disease was the prime cause for HF in men and women but more so in men (P < .001). Women had higher rates of hypertensive heart disease and primary valve disease (P < .001, for both comparisons). Men were more likely to have severe left ventricular systolic dysfunction. On discharge, a higher use of angiotensin-converting enzyme inhibitors, ß-blockers, and aldosterone inhibitors was observed in men (P < .001 for all comparisons). Apart from higher atrial fibrillation in women and higher ventricular arrhythmias in men, no differences were observed in hospital outcomes. The overall survival did not differ between men and women (hazard ratio: 1.0, 95% confidence interval: 0.8-1.2, P = .981). Men and women with AHF differ significantly in baseline clinical characteristics and management but not in adverse outcomes.

Neisseria gonorrhoeae and fosfomycin: Past, present and future.

Drug-resistant Neisseria gonorrhoeae has become a global health concern that requires immediate attention. Due to increasing resistance to cephalosporins, pursuing novel alternatives for treating N. gonorrhoeae infections is paramount. Whilst new drug development is often cumbersome, reviving antiquated antibiotic agents for treatment of modern infections has become prevalent in clinical practice. Fosfomycin exhibits bactericidal activity through a unique mechanism of action, and a variety of organisms including N. gonorrhoeae are susceptible. In vitro studies have demonstrated that fosfomycin can retain activity against ceftriaxone-resistant N. gonorrhoeae; however, it remains unclear whether there is synergy between fosfomycin and other antibiotics. Clinical investigations evaluating fosfomycin for the treatment of N. gonorrhoeae infections are confounded by methodological limitations, none the less they do provide some perspective on its potential role in therapy. Future studies are needed to establish a safe, convenient and effective fosfomycin regimen for treating N. gonorrhoeae infections.

Clinical features, management, and short- and long-term outcomes of patients with acute decompensated heart failure: phase I results of the HEARTS database.

AIMS: The HEart function Assessment Registry Trial in Saudi Arabia (HEARTS) is a national multicentre project, studying clinical features, management, short- and long-term outcomes, and mortality predictors in patients admitted with acute decompensated heart failure (ADHF). METHODS AND RESULTS: Our prospective registry enrolled 2610 ADHF patients admitted to 18 hospitals in Saudi Arabia between October 2009 and December 2010, and followed mortality rates until January 2013. The patients included 66% men and 85.5% Saudis, with a median age (interquartile range) of 61.4 (15) years; 64% had acute on chronic heart failure (HF), 64.1% diabetes mellitus, 70.6% hypertension, and 55.7% CAD. Exacerbating factors for hospital admission included acute coronary syndromes (37.8%), infections (20.6%), non-compliance with low-salt diet (25.2%), and non-compliance with HF medications (20%). An LVEF<40% was found in 73%. In-hospital use of evidence-based medications was high. All-cause cumulative mortality rates at 30 days, 6 months, 1 year, 2 years, and 3 years were 8.3, 13.7, 19.5, 23.5, and 24.3%, respectively. Important independent predictors of mortality were history of stroke, acute on chronic HF, systolic blood pressure<90 mmHg upon presentation, estimated glomerular filtration rate<60 mL/min, and haemoglobin<10 g/dL. CONCLUSION: Patients with ADHF in Saudi Arabia presented at a younger age and had higher rates of CAD risk factors compared with those in developed countries. Most patients had reduced LV systolic function, mostly due to ischaemic aetiology, and had poor long-term prognosis. These findings indicate a need for nationwide primary prevention and HF disease management programmes.

Impact of diabetes on hospital adverse cardiovascular outcomes in acute coronary syndrome patients: Data from the Saudi project of acute coronary events.

BACKGROUND: Diabetes mellitus (DM) is a major public health problem in Saudi Arabia. DM patients who present with acute coronary syndrome (ACS) have worse cardiovascular outcomes. We characterized clinical features and hospital outcomes of diabetic patients with ACS in Saudi Arabia. METHODS: ACS patients enrolled in the Saudi Project for Assessment of Acute Coronary Syndrome (SPACE) study from December 2005 to December 2007, either with DM or newly diagnosed during hospitalization were eligible. Baseline demographics, clinical presentation, therapies, and in-hospital outcomes were compared with non-diabetic patients. RESULTS: Of the 5055 ACS patients enrolled in SPACE, 2929 (58.1%) had DM (mean age 60.2 ± 11.5, 71.6% male, and 87.6% Saudi nationals). Diabetic patients had higher risk-factor (e.g., hypertension, hyperlipidemia) prevalences and were more likely to present with non-ST-elevation myocardial infarction (40.2% vs. 31.4%, p < 0.001), heart failure (25.4% vs. 13.9%, p < 0.001), significant left ventricular systolic dysfunction and multi-vessel disease. Diabetic patients had higher in-hospital heart failure, cardiogenic shock, and re-infarction rates. Adjusted odds ratio for in-hospital mortality in diabetic patients was 1.83 (95% CI, 1.02-3.30, p = 0.042). CONCLUSIONS: A substantial proportion of Saudi patients presenting with ACS have DM and a significantly worse prognosis. These data highlight the importance of cardiovascular preventative interventions in the general population.

Design and preliminary results of the heart function assessment registry trial in Saudi Arabia (HEARTS) in patients with acute and chronic heart failure.

AIMS: The heart function assessment registry trial in Saudi Arabia (HEARTS) is the first multicentre national quality improvement initiative in the Arab population to study the clinical features, management, and outcomes of inpatients admitted with acute heart failure (AHF) and outpatients with high-risk chronic heart failure (HCHF). METHODS AND RESULTS: We conducted a prospective pilot phase for the registry that included consecutive patients with AHF and HCHF in five tertiary care hospitals in Saudi Arabia between October 2009 and December 2010. The study enrolled 1090 patients, 722 (66.2%) of whom were admitted with AHF and 368 (33.8%) had HCHF. The mean age ± SD of AHF patients was 60.6 ± 15.3 years; 65.2% were men, 55.3% were de novo heart failure, 60.7% had diabetes mellitus, 72.5% had moderate or severe left ventricular (LV) systolic dysfunction, and 51.5% had coronary artery disease as the main aetiology. More than 80% of AHF and HCHF patients were treated with beta-blockers and angiotensin-converting enzyme inhibitors/angiotensin receptor blockers. Patients with HCHF had a similar clinical profile, but only one-third had implantable cardioverter defibrillators. In-hospital mortality was 5.3% for AHF patients and 7.5% at 30 days after hospital discharge. CONCLUSION: Heart failure patients in Saudi Arabia present at a relatively younger age, have a much higher rate of diabetes mellitus, and predominantly have LV systolic dysfunction, which is mainly ischaemic in origin, compared with patients in developed countries. The preliminary results of the study show potential targets for improvement in care.

Baseline characteristics, management practices, and in-hospital outcomes of patients with acute coronary syndromes: Results of the Saudi project for assessment of coronary events (SPACE) registry.

OBJECTIVES: The Saudi Project for Assessment of Coronary Events (SPACE) registry is the first in Saudi Arabia to study the clinical features, management, and in-hospital outcomes of acute coronary syndrome (ACS) patients. METHODS: We conducted a prospective registry study in 17 hospitals in Saudi Arabia between December 2005 and December 2007. ACS patients included those with ST-elevation myocardial infarction (STEMI), non-ST elevation myocardial infarction and unstable angina; both were reported collectively as NSTEACS (non-ST elevation acute coronary syndrome). RESULTS: 5055 patients were enrolled with mean age ± SD of 58 ± 12.9 years; 77.4% men, 82.4% Saudi nationals; 41.5% had STEMI, and 5.1% arrived at the hospital by ambulance. History of diabetes mellitus was present in 58.1%, hypertension in 55.3%, hyperlipidemia in 41.1%, and 32.8% were current smokers; all these were more common in NSTEACS patients, except for smoking (all P < 0.0001). In-hospital medications were: aspirin (97.7%), clopidogrel (83.7%), beta-blockers (81.6%), angiotensin converting enzyme inhibitors/angiotensin receptor blockers (75.1%), and statins (93.3%). Median time from symptom onset to hospital arrival for STEMI patients was 150 min (IQR: 223), 17.5% had primary percutaneous coronary intervention (PCI), 69.1% had thrombolytic therapy, and 14.8% received it at less than 30 min of hospital arrival. In-hospital outcomes included recurrent myocardial infarction (1.5%), recurrent ischemia (12.6%), cardiogenic shock (4.3%), stroke (0.9%), major bleeding (1.3%). In-hospital mortality was 3.0%. CONCLUSION: ACS patients in Saudi Arabia present at a younger age, have much higher prevalence of diabetes mellitus, less access to ambulance use, delayed treatment by thrombolytic therapy, and less primary PCI compared with patients in the developed countries. This is the first national ACS registry in our country and it demonstrated knowledge-care gaps that require further improvements.

Adaptive and longitudinal pharmaceutical care instruction using an interactive voice response/text-to-speech system.

OBJECTIVES: To develop a course structure that would more closely simulate the actual provision of pharmaceutical care. DESIGN: An interactive voice response/text-to-speech system (hardware and software) for obtaining patient data was designed and used in a pharmaceutical care laboratory. Students called the system to collect data, listen to progress notes, make recommendations, and update the pharmaceutical care plan for virtual patients. Laboratory time was utilized to evaluate patient progress and respond to recommendations as well as to identify and solve drug-related problems. ASSESSMENT: Students' recorded communications with the system and completed care plans were evaluated and a competency-based final examination was administered. Peer evaluations and course evaluations were administered. CONCLUSION: This innovative approach challenged students and promoted interactive learning. Student evaluations indicated we achieved our objective of creating a course that more closely simulated the actual provision of pharmaceutical care.
