RESUMEN
BACKGROUND: Chronic kidney disease (CKD) has emerged as a significant global health concern, with its incidence doubling over the past three decades. Cardiovascular diseases (CVD) pose a major threat to CKD patients, surpassing the risk of progressing to end-stage renal disease. While previous studies worldwide have shed light on this association, limited research has been conducted in Saudi Arabia regarding this burden. This study aims to fill this gap by identifying the prevalence and risk factors of CVD in CKD patients at King Abdulaziz University Hospital (KAUH), Jeddah, Saudi Arabia, between 2017 and 2022. METHODS: A six-year retrospective review of medical records at KAUH was conducted, including 465 non-end-stage CKD patients aged 30 to 79. Data, including demographics, clinical information, and laboratory results, were collected and statistically analyzed to investigate the association between variables. RESULTS: Out of 465 CKD patients, 262 (56.3%) were diagnosed with CVD, with congestive heart failure and ischemic heart disease being the most common types. The majority were male 259 (55.7%), non-Saudi 278 (59.8%), and aged 60 years and older 291 (62.6%). Hypertension 394 (84.7%) and diabetes mellitus 336 (72.3%) were prevalent comorbidities. Severely reduced left ventricular ejection fraction, proteinuria, diabetes mellitus, and higher BMI were identified as significant risk factors for CVD in CKD patients. CONCLUSION: This research contributes valuable insights into the prevalence and risk factors of CVD in CKD patients in Saudi Arabia, emphasizing the need for early detection and intervention. The identified risk factors provide a basis for developing targeted preventive strategies to mitigate this population's CVD burden.
RESUMEN
BACKGROUND: Hypertension (HTN) is the most significant modifiable risk factor for cardiovascular disease (CVD) and overall mortality. HTN is defined as a systolic blood pressure of ≥140 mmHg and/or a diastolic blood pressure of ≥ 90 mmHg. Generally, arrhythmias are characterized by a disruption of the heart's regular rhythm. They are strongly associated with increased risks of CVDs and sudden death. The most common arrhythmia worldwide is atrial fibrillation (AF). HTN, diabetes mellitus (DM), and coronary artery disease (CAD) are major risk factors for arrhythmias. OBJECTIVE: We aimed to identify the postoperative effects and risk factors of HTN and cardiac arrhythmia in patients who underwent cardiac surgery at King Abdulaziz University Hospital (KAUH) from 2015 to 2022. METHODS: A retrospective record review was conducted by collecting data from KAUH electronic medical records. A total of 402 patients participated in this study. This study includes all hypertensive and arrhythmic patients who underwent cardiac surgeries. RESULTS: Of the 402 patients studied, 209 had pre-operative HTN, and 47 had preoperative AF. Developing post-operative arrhythmia was found to significantly increase perioperative morbidity and mortality (p < 0.001). Risk factors for HTN and arrhythmia included increased age, higher BMI, and DM. CONCLUSION: The findings of this study suggest an association between preoperative HTN and AF and elevated rates of postoperative morbidity and mortality. AF emerged as the predominant arrhythmia type. It is advisable to optimize patients' health status prior to surgical procedures. Moreover, further research is recommended in this field to deepen our understanding of the perioperative implications of HTN and arrhythmias.
