RESUMO
INTRODUCTION: Heart failure (HF) affects about 320,000 Saudi individuals and is associated with a considerable negative impact on the patients' quality of life. In literature, there is a lack of data about the echocardiographic abnormalities of HF patients in Saudi Arabia. AIM OF WORK: To describe the echocardiographic findings of HF patients in Western Saudi Arabia. METHODOLOGY: This was a retrospective record review study conducted on 2000 patients with chronic HF in Saudi Arabia. Demographic, clinical and echocardiographic data were collected and compared among patients with HF with reduced ejection fraction (HFrEF), ie, EF≤40%; HF with mid-range EF (HFmrEF), ie, EF=41-49%; and HF with preserved EF (HFpEF), ie, EF≥50%. RESULTS: Among the 2000 patients studied, females constituted 46.3% of the sample. About 52% of females had HFpEF, whilst 70% of males had HFrEF (p<0.0001). Diastolic dysfunction occurred in 98% of HFpEF versus 78% of HFrEF (p<0.0001). Patients with HFrEF had higher left-ventricular diastolic (LVd) volume (1536 versus 826), higher left-ventricular systolic (LVs) volume (1660 vs 772), higher left atrial volume (1344 vs 875), higher aortic root dimension (1144 vs 929) and lower fractional shortening (FS) (267 vs 1213) than patients with HFpEF (p<0.0001). CONCLUSION: HFpEF was more common among females and was associated with higher rates of diastolic dysfunction and higher FS. HFrEF was prevalent among males and associated with higher LVd, LVs, left atrium volume and aortic root dimensions.
RESUMO
BACKGROUND: Mitral valve prolapse (MVP) is the most common cardiac valvular abnormality in developed countries and it is associated with considerable morbidity and mortality. AIM OF WORK: To study the clinical presentations, risk factors, and echocardiographic features of patients with MVP in Jeddah, Saudi Arabia. MATERIALS AND METHODS: A retrospective chart review study was conducted in King Abdulaziz teaching hospital in Jeddah, Saudi Arabia, from 2007 to 2017. All patients with MVP who were admitted at the hospital during this time period were recruited to this study, and demographic, clinical, and echocardiographic variables were analyzed using IBM SPSS. RESULTS: Ninety-seven patients were recruited to this study, with a mean age of 43.82±16.16 years. Females constituted 67%. The body mass index (BMI) was 24.9±6.3 kg/m2. Hypertension, diabetes, and dyslipidemia occurred in 19.6%, 5.2%, and 5.2% of patients, respectively. A single patient had Marfan syndrome. Chest pain, palpitations, and dyspnea were the presenting symptoms in 23.7%, 11.3%, and 9.3% of patients, respectively, with elderly individuals presenting disproportionally (93.3%) with palpitations. Fifty-five percent of patients had an anterior leaflet prolapse. The presence of posterior leaflet prolapse and severe mitral regurgitation (MR) was significantly associated with left atrial and left ventricular dilatation (P<0.05 and P<0.001, respectively). CONCLUSION: MVP is more prevalent in women and middle-aged individuals with normal BMIs in this population. The most common clinical presentations were chest pain, palpitations, and dyspnea, which did not differ significantly with age or gender. The anterior leaflet was the most commonly prolapsed in the studied patients and presented with mild MR. Posterior leaflet MVP, while of low prevalence, was associated with severe MR and poor left ventricular function.
RESUMO
BACKGROUND: Coronary artery disease (CAD) is a serious cardiovascular disorder affecting middle-aged individuals. It is a major cause of death among adults over the age of 35 years. In Saudi Arabia, CAD is associated with higher mortality rate, and Saudi patients are reported to have significantly higher prevalence of risk factors for CAD than the Western population. Furthermore, as, to date, there is no definite cure for CAD, prevention of the disease and tight control of the known risk factors are the cornerstones for reducing CAD-associated mortality. Thus, the present work aimed to assess the population awareness of CAD risk factors in Saudi Arabia. METHODS: A cross-sectional study was conducted in Jeddah during the period January 2017 to December 2017 by using an online survey questionnaire to assess participants' awareness of 14 risk factors for CAD, namely: smoking, lack of physical activity, fast food and soft drink intake, television and computer use; history of diabetes mellitus, myocardial infarction and stroke; as well as a family history of diabetes mellitus, diabetes, hypertension, hyperlipidemia, CAD and myocardial infarction. RESULTS: Of 468 respondents, 41% were males. The mean age was 31.9±12.4. Approximately 86% were Saudi, and ~60% had a university education. The mean overall awareness score was 4.31±1.36 (1.00-8.00). Fast food, soft drinks, and family history of diabetes were the most commonly identified risk factors, reported by 74.8%, 64.3%, and 47.2% of participants, respectively. There was a strong correlation between overall awareness score and awareness of each risk factor individually (P<0.003). CONCLUSION: There is an evident limited knowledge among the population in Jeddah, Saudi Arabia regarding the risk factors for CAD, and it is recommended that the healthcare sector in the country focus on public health education programs about the disease.
RESUMO
BACKGROUND: Providing basic life support (BLS) at the site of an accident is crucial to increase the survival rates of the injured people. It is especially relevant when health care is far away. OBJECTIVE: The aim of our study is to assess the BLS knowledge level of the Saudi Arabian population and identify influencing factors associated with level of knowledge about BLS. METHODS: Our study is a cross-sectional descriptive study, which was conducted using a self-administered online questionnaire derived from the BLS practice test. The Saudi population was the target population. The questionnaire was divided into two parts: one contained demographic data and the second part contained questions to test the population's perception about how to perform BLS techniques properly. The data were collected between July and August 2017. Statistically significant differences were defined as those with a P value <.05, and a score of five or more was considered a passing score on the second part. We used SPSS version 21 for data analysis. RESULTS: Our study included 301 participants. Our participants' BLS online exam scores ranged from 0 to 10, with a mean of 4.1 (SD 1.7). Only 39.2% (118/301) of the participants passed the test. The percentage of bachelor's degree or higher holders constituted 60.1% (181/301) of the study population. In addition, higher income was significantly associated with higher scores on the test (P=.04). CONCLUSIONS: This study demonstrated that the theoretical knowledge level of BLS among the general population in Jeddah was below average. There is a critical need to increase the public's exposure to BLS education through raising awareness campaigns and government-funded training programs that aim to curb the incidence of out-of-hospital cardiac arrest mortalities in the Saudi community.
