The Prevalence of Depression in Survivors of Acute Myocardial Infarction and Gender Differences in King Abdulaziz Medical City (KAMC), Riyadh.

BACKGROUND: Myocardial infarction (MI) stands as a prevalent worldwide cause of mortality. The aftermath of an MI often entails an unpleasant experience for individuals, who frequently find themselves overwhelmed. Extensive literature suggests that a significant proportion of patients develop depressive symptoms subsequent to MI. Consequently, the primary objective of this study is to ascertain the prevalence of post-MI depression among affected individuals. METHODS: This is a cross-sectional study involving a survey distributed to patients admitted to the King Abdulaziz Medical Center (KAMC) located in Riyadh, Saudi Arabia. The study involved 210 patients; 72.1% of the sample were men and 27.9% were female. RESULTS: The average age of the participants in this study was 61.96 years old. The mean age of the male participants was 61.10 years old, while the females' mean age was 64.35 years old. Males made up 75.27% of the participants, while 24.73% were females. Overall, 33.64% of the participants had an abnormal score (depression). The majority of male patients had a normal score, which means that they do not suffer from depression. Among the female patients, 38.60% had an abnormal score. CONCLUSION: Mental illness is a significant concern, particularly depression. Individuals should go for depression screening post-MI as it will determine their compliance with visiting the hospital, caring for themselves, and taking medications.

Simultaneous Transcatheter Closure of a Ventricular Septal Defect and Pulmonary Valvuloplasty: A Case Report.

BACKGROUND Congenital heart diseases (CHDs) are the most common form of birth defects, affecting the structure and function of neonatal hearts. Pulmonary valve stenosis (PVS) and ventricular septal defects (VSD) are 2 of the more prevalent forms, both of which can lead to significant morbidity if left untreated. The emergence of transcatheter techniques has revolutionized the therapeutic landscape, presenting minimally invasive yet effective alternatives to open-heart surgery and significantly reducing associated patient morbidity and recovery time. CASE REPORT The presented case details the management of a 19-year-old man with complex CHDs, highlighting the nuanced decision-making process that led to a transcatheter approach. The patient's clinical presentation, marked by symptoms reflective of significant cardiac compromise, demanded a tailored approach that utilized the latest advancements in non-surgical intervention. The successful closure of the VSD with an Amplatzer device and the resolution of PVS via balloon valvuloplasty were achieved without complications, showcasing the potential of these techniques in managing similar cases. The post-intervention period was marked by a noteworthy recovery, confirming the procedural efficacy and enhancing the patient's quality of life. CONCLUSIONS The favorable outcome of this case highlights the pivotal role of transcatheter interventions in treating complex CHDs and suggests a shift towards less invasive approaches in cardiac care. This case contributes valuable insights to the existing body of evidence, reinforcing the potential of transcatheter techniques to become the preferred treatment modality. With promising immediate and short-term results, these techniques highlight the need for continued research into their long-term efficacy and application across diverse patient demographics.

The Ross Procedure in a Case of Baraitser-Winter Syndrome: A Case Report.

Baraitser-Winter syndrome (BRWS) is a rare genetic disorder caused by mutations in the ACTB and ACTG1 genes. It is characterized by intellectual disability, physical malformations, and dysmorphic craniofacial features. Additionally, cardiovascular abnormalities may also be present. We present a case of a 15-year-old boy with BRWS associated with congenital bicuspid aortic valve and severe aortic insufficiency which was managed successfully with Ross procedure.

A Case Report of Yamaguchi Syndrome in a Saudi Male.

Apical hypertrophic cardiomyopathy, also called Yamaguchi syndrome, is a rare variant of hypertrophic cardiomyopathy. Yamaguchi syndrome is characterized by hypertrophy almost confined to the apical region of the left ventricle rather than the left ventricular septum. A case of 65-year-old Saudi man presented to the ER with angina, and the ECG, echocardiogram, and nuclear study confirmed the diagnosis with Yamaguchi. Reporting this case serves to help physicians broaden their vision in approaching patients with symptoms mimicking acute coronary syndrome.

Acute Myocardial Infarction Associated With Amphetamine Use and Smoking in a Young Healthy Individual.

One of the primary causes of death among methamphetamine users is cardiovascular disease, which is a result of the narrowing and spasm of blood vessels caused by the drug. This leads to increased blood pressure and heart rate, which can damage the heart muscle at the molecular level. The most common forms of chronic cardiovascular disease associated with methamphetamine use are coronary artery disease and cardiomyopathy. Here, we report a case of myocardial infarction (MI) due to amphetamine use and smoking in a young healthy male who developed ST-elevation myocardial infarction, ventricular fibrillation (VF), and cardiac arrest. A 28-year-old male presented to the emergency department with chest pain and shortness of breath during exercise. Immediately upon presentation, electrocardiography was done which initially showed sinus tachycardia that progressed to right bundle branch block and ST elevation with a shark fin morphology, followed by VF and cardiac arrest. He was resuscitated and underwent percutaneous coronary intervention with stenting of the left anterior descending artery. Cardiotoxic manifestations such as acute MI, heart failure, or arrhythmia related to misuse of amphetamines have been rarely documented. This case report describes the clinical course and management of a young male patient who suffered a life-threatening cardiac event triggered by smoking and amphetamine abuse.

The Prevalence of Hyperthyroidism Amongst Atrial Fibrillation Patients in the National Guard Hospital, Riyadh, Saudi Arabia: A Cross-Sectional Retrospective Study.

Introduction The thyroid gland is the largest pure endocrine gland. It is also responsible for the production of multiple important hormones that regulate heart function. Dysfunction of the thyroid gland could lead to hyperthyroidism, which in turn leads to many lipid and cardiovascular problems. One such cardiac condition that is highly associated with hyperthyroidism is atrial fibrillation. Atrial fibrillation is when abnormal electrical impulses suddenly start firing in the atria. With a prevalence of 16% to 60% of atrial fibrillation in hyperthyroid patients. To the best of our knowledge, no similar study was conducted in Saudi Arabia. Objectives Our study aims to investigate the percentage of people with atrial fibrillation that is caused by hyperthyroidism in the National Guard Hospital. Moreover, we hope that this study will improve the quality of life of these affected patients and add to their knowledge of medicine. Methods Since the population size has increased by approximately 4000 patients in the last five years, we estimated the sample size based on a confidence interval of 95% and a level of significance of 5%, which is 350 patients. We included all patients with atrial fibrillation due to hyperthyroidism in KAMC-R and patients' records from 2015 to 2020. Also, we excluded all patients with atrial fibrillation due to other causes. In addition, the sampling method we used was convenient sampling. Result Out of 1100 patients with hyperthyroidism or subclinical hyperthyroidism, 40 or 3.6% of the patients had atrial fibrillation, while the rest were distributed among dilated cardiomyopathy, diabetes mellitus, heart failure, and other risk factors for atrial fibrillation. Conclusion We conclude that hyperthyroidism is a risk factor for atrial fibrillation; 3.6% of hyperthyroidism patients have atrial fibrillation. Most of the patients are elderly, and more than half (58%) are female.

Shark Fin Electrocardiogram: A Deadly Electrocardiogram Pattern in Takotsubo Cardiomyopathy During 15 Years of Follow-Up.

Takotsubo cardiomyopathy (TTC) or stress-induced cardiomyopathy is characterized by transient left ventricular apical ballooning in the absence of coronary occlusion. Although the underlying mechanism is still unknown, exaggerated sympathetic nervous system and catecholamine cardiotoxicity, followed by metabolic disturbance, and multi-vessel epicardial coronary artery vasospasm, are thought to be responsible for the development of this condition. TTC accounts for 1-2% of patients presenting with the acute coronary syndrome (ACS) with the majority of patients being postmenopausal women. Shark fin electrocardiogram (SFE) or triangular ST-segment elevation is an uncommon electrocardiogram (ECG) finding that is typically associated with an increased risk of ventricular fibrillation and cardiogenic shock, thus, it is considered a poor prognostic factor. We present a case of a 57-year-old postmenopausal female with TTC post-colonic perforation. Upon further investigation, an ECG revealed an SFE or triangular ST-segment elevation on the anterolateral leads, and an elevated serum troponin level was found. On trans-thoracic echocardiogram (TTE), hypokinesis and akinesis of the apex and left ventricular segments were observed with sparing of the basal segments. Eventually, the patient was successfully managed and monitored until regain of normal function.

Incremental prognostic value of positron emission tomography-derived myocardial flow reserve in patients with and without diabetes mellitus.

AIMS: We aimed to assess the incremental prognostic value of positron emission tomography (PET)-derived myocardial flow reserve (MFR) among patients with diabetes and those without diabetes. METHODS AND RESULTS: Consecutive patients with clinically indicated PET MPI for suspected or established coronary artery disease (CAD) were included. Myocardial blood flow (MBF) in mL/min/g was obtained from dynamic images at rest and stress, while MFR was calculated as the ratio of stress to rest MBF. Patients were followed from the date of PET imaging for the occurrence of the primary outcome (composite of all-cause death, myocardial infarction, and un-planned percutaneous coronary intervention/coronary artery bypass graft occurring more than 90 days after imaging). The final cohort consisted of 6019 patients (63% with diabetes) (mean age 61 ± 11 years, 45% female, 55% obese, 76% hypertensive, and 62% dyslipidaemia). Over half (53%) of the patients had an impaired MFR (<2). During a median follow-up of 22.6 (7.8-42.5) months, 619 patients (10%, 3.8 per 1000 person-years) experienced the primary outcome. Impaired MFR (MFR < 2) was significantly associated with the primary outcome in patients with and without diabetes (diabetes: HR 1.8, 95% CI 1.4-2.3, P < 0.001; no diabetes: 1.4, 95% CI 1.0-2.1, P = 0.046). There was no interaction between diabetes status and MFR (P = 0.234). Results were consistent across subgroups of patients with no CAD and normal perfusion study. CONCLUSION: PET-derived MFR has a strong independent and incremental prognostic role in patients with diabetes and those without diabetes.

A Forme Fruste of Marfan Syndrome: A Case Report.

Marfan syndrome (MFS), an inherited connective tissue disorder, is caused by a mutation in the FBN1 gene. MFS is characterized by manifestations in the musculoskeletal system (joint laxity, scoliosis), the cardiovascular system (aortic dilation), and the ocular system (ectopic lens). We report a case of a 37-year-old male with a genetically confirmed MFS. His mother and brother were also both confirmed cases of MFS. While the patient exhibited the characteristic physical features of MFS in general appearance, he did not show any cardiac manifestations of the disease. This report highlights a case of the familial occurrence of MFS and emphasizes the importance of recognizing the forme fruste of MFS.

Knowledge and Awareness of Syncope Among the Population of Riyadh: A Cross-Sectional Study.

Background Although syncope is a common emergency in medical settings, no research has yet evaluated the general population's awareness regarding it. This study investigated the general population's knowledge and awareness of syncope and if they could differentiate syncopal and non-syncopal causes of transient loss of consciousness (TLOC). Methodology A cross-sectional study was conducted in Riyadh through a validated, self-administered Arabic questionnaire that was distributed to the general population through social media using Google Forms (convenience sampling). Participants younger than 18 or not from Riyadh were excluded from the study. Two cardiologists validated the questionnaire, following which forward and backward translation was done. The questionnaire contained three sections. The first section included demographic data and chronic conditions. In the second section, participants were asked if they or one of their relatives had ever experienced syncope. The third section had eight scenarios assessing the participants' syncope knowledge. Subjects with ≥five correct answers were considered to be aware. Results The number of total responses was 405 participants. Regarding demographic data, 53% of the participants were female, 33% had a medical background, and 76% had a university degree (n = 214, n = 134, and n = 306, respectively). The mean age of the participants was 33.2 ± 13.3 years. Participants who were aware of syncope represented 55% (n = 221). Among the syncope cases, orthostatic syncope had the highest number of correct answers (79%, n = 319), followed by vasovagal syncope (61%, n = 246). Males performed better in cases one (p = 0.001), two (p = 0.004), and seven (p = 0.01). Conclusions The results of this study showed that most participants were considered aware of syncope. Gender, marital status, and having a medical background had a significant influence on the results.

Refractory Salmonella Prosthetic Valve Endocarditis Complicated by Splenic Infarction and Aortic Pseudoaneurysm in a Patient with Double Prosthetic Valves: A Case Report.

Endocarditis is an extremely rare complication of Salmonellosis with an incidence of 0.2-0.4%. It is a destructive and invasive infection that follows a highly complicated course and carries a high mortality rate that exceeds 45%. Multiple predisposing factors for Salmonella endocarditis have been described in the literature, including human immunodeficiency virus infection, congenital heart diseases, and the presence of a prosthetic valve. Herein, we report a case of Salmonella prosthetic valve endocarditis complicated by splenic infarction and aortic pseudoaneurysm presenting as a month-long history of fluctuating fever, chills, and rigors, accompanied by occasional cough and shortness of breath in a 55-year-old female with aortic and mitral valves replacement and multiple comorbidities. She was diagnosed by multiple radiographic studies and successfully treated with the Commando procedure and a long course of IV antibiotics.

Prevalence of Self-Reported Muscle Pain Among Statin Users From National Guard Hospital, Riyadh.

Background Statin, a hydroxymethylglutaryl-coenzyme A reductase inhibitor, is one of the commonly used lipid-lowering drugs that is used for lowering lipid levels in the body. Muscle pain is a commonly reported adverse effect of statins, yet little is known about the prevalence of muscle pain and statin use in the general population. Methods The cross-sectional study was conducted in National Guard Hospital, Riyadh, Saudi Arabia. All study subjects were adult statin users aged 18 years old or above. A total of 313 patients were included in the study. The study was conducted based on a questionnaire distributed among patients according to inclusion and exclusion criteria. Results Among 313 statin users, patients underwent cardiac catheterization (39, 12.5%), stress test (62; 19.8%), percutaneous coronary intervention (three; 1.0%), and coronary artery bypass graft (six, 1.9%), while 203 patients didn't have any intervention (64.9%). Most of the study subjects were on atorvastatin (139; 44.4%). The prevalence of muscle pain was 73.5%; 95% CI = (68.4% - 78.1%). The most common sites of pain were lower limb pain (160; 51.1%), upper limb pain (145; 46.3%), and trunk pain (96; 30.7%). The common types of pain were joint pain (52; 16.6%), muscle weakness (51; 16.3%), muscle aches (43; 13.7%), and muscle cramps (41; 13.1%); and patients who reported that they stopped statin at some point because of muscle pain were 92 (29.4%). Conclusion Statins are important for managing and preventing ischemic heart diseases. Our study found that muscle pain is highly associated with statin use with a prevalence of 73.5%, which causes many patients to tend to stop taking their medication. Therefore, preventing the side effects by adjusting the proper dose or switching to another type of statin for high-risk patients will help them to continue using the drug. Also, it is important to rule out secondary causes of myopathy such as physical activity, fracture, thyroid dysfunction, or infection.

Myocardial Flow Reserve and Coronary Calcification in Prognosis of Patients With Suspected Coronary Artery Disease.

OBJECTIVES: The aim of this analysis is to examine the incremental prognostic value of coronary artery calcium (CAC) score and myocardial flow reserve (MFR) in patients with suspected coronary artery disease (CAD) undergoing positron emission tomography (PET) myocardial perfusion imaging (MPI). BACKGROUND: Advances in cardiac PET and computed tomography imaging enabled the simultaneous acquisition of anatomic and physiological data for patients suspected of CAD. METHODS: Consecutive patients who underwent PET MPI and CAC score calculation at King Abdulaziz Cardiac Center, Riyadh, Saudi Arabia, between May 2011 and May 2018 were included in the study. MPI and CAC images were obtained in the same setting. The primary endpoint of the study was a composite of cardiac death and nonfatal myocardial infarction. Cox proportional hazard regression was used to assess the incremental prognostic value of CAC and MFR by sequentially adding the variables to a model that included clinical and PET variables. RESULTS: A total of 4,008 patients (mean age 59.7 ± 11.6 years, 55% women) were included in the analysis. Risk factors were prevalent (77.6% hypertension, 58.1% diabetes). In total, 35.9% of the cohort had CAC of 0, 16.5% had CAC ≥400, and 43.9% had MFR <2. Over a median follow up of 1.9 years, 130 (3.2%) patients had cardiac death/nonfatal myocardial infarction. CAC and MFR score added incremental prognostic value over clinical and perfusion variables (base model: c-index 0.8137; Akaike information criterion [AIC]: 1,865.877; p = 0.0011; CAC model: c-index = 0.8330; AIC: 1,850.810; p = 0.045 vs. base model; MFR model: c-index = 0.8279; AIC: 1,859.235; p = 0.024). Combining CAC and MFR did not enhance risk prediction (c-index = 0.8435; AIC: 1,846.334; p = 0.074 vs. MFR model; p = 0.21 vs. CAC model.) CONCLUSIONS: In this large cohort of patients referred for PET MPI, both CAC and MFR independently added incremental prognostic value over clinical and MPI variables. Although combining both may have synergetic prognostic effect, this relation was not shown in multivariable model of this analysis.

The prevalence of non-syndromic orofacial clefts and associated congenital heart diseases of a tertiary hospital in Riyadh, Saudi Arabia.

BACKGROUND: Orofacial clefts are considered one of the most common birth defects and are frequently associated with other malformations. Congenital heart disease is one of the most prevalent congenital malformation. OBJECTIVE: To investigate the prevalence of congenital heart diseases associated with non-syndromic orofacial clefts in the Saudi population. METHODS: Electronic files of non-syndromic orofacial cleft patients who visited the Oral and Maxillofacial Surgery Department in King Abdulaziz Medical City of Riyadh, Saudi Arabia from January 2015 to December 2018 were retrospectively reviewed. Data were recorded in an excel sheet and analyzed using SPSS via frequency tests. RESULTS: In the cleft children identified, the prevalence of non-syndromic orofacial clefts was (77%). Orofacial clefts showed a male predominance (62%). The most common orofacial phenotype was unilateral cleft lip and palate (34%). The prevalence of associated congenital malformations with orofacial clefts was (41%). The most prevalent congenital malformation was congenital heart disease (35%), mainly found in unilateral cleft lip and palate patients (33%). The prevalence of associated congenital heart disease with orofacial clefts was (19%). The most frequent type of congenital heart disease was atrial septal defect (37%). CONCLUSION: This study highlights the recognition of the associated congenital heart disease with non-syndromic orofacial cleft patients. Global screening protocols designed for newborns with non-syndromic orofacial cleft are needed to eliminate late diagnosis of critical congenital heart diseases which might present operative risks of anesthesia and/or surgical procedures.

Thirty-day readmission rates and associated risk factors after coronary artery bypass grafting.

OBJECTIVES: Coronary artery bypass grafting (CABG) is among the most frequently performed cardiac surgical procedures. However, it is associated with high readmission rates for a plethora of causes, which can substantially increase healthcare costs. This study aimed to assess the rates and associated risk factors of 30-day readmissions for CABG patients. METHODS: We conducted this retrospective cohort study at King Abdulaziz Medical City. The study targeted adult patients who underwent CABG between January 1, 2016, and January 31, 2019. Data were extracted from the BEST Care system. Frequencies and percentages were generated for categorical variables. Mean and standard deviation were calculated for quantitative variables. Bivariable and multivariable logistic regressions were used to detect readmission risk factors. RESULTS: Among 534 adult patients, the overall 30-day readmission rate was 16.1% (n = 86). The multivariable logistic regression analysis showed that diabetes mellitus (P = .002), amiodarone use (P = .04), statin use (P = .04), amlodipine use (P = .006), asthma (P < .001), and hyperlipidemia (P = .04) were significantly correlated with 30-day readmission. CONCLUSIONS: Our study showed an estimated 16.1% 30-day readmission rate after CABG. Diabetes mellitus, asthma, hyperlipidemia, and use of medications such as amiodarone, statins, and amlodipine were associated with readmission. Further studies are needed to develop tailored and practical strategies to reduce CABG readmissions and mitigate patient and health care facility burdens.

Surgical Management and Outcomes of Homozygous Familial Hypercholesterolemia in Two Cousins: A Rare Case Report.

Homozygous familial hypercholesterolemia (HoFH) is a rare life-threatening condition characterized by high levels of low-density lipoprotein (LDL) cholesterol in the blood, which increases a person's risk of developing early atherosclerotic cardiovascular disease (ASCVD). In this report, we present two cases of related patients with aortic stenosis and mitral regurgitation as complications of HoFH. We also discuss the surgical interventions they underwent and their outcomes. The two related patients with HoFH were admitted to our hospital with signs and symptoms of heart failure. Physical examination revealed an ejection systolic murmur over the aortic valve. Echocardiography revealed valvular disease, and coronary angiography revealed coronary artery disease (CAD). They had undergone the Bentall procedure, mitral valve replacement, and coronary artery bypass graft (CABG) surgery. We elaborate on the progressive course of HoFH, the possible complications associated with this condition, treatment options, and prognosis for the disease. HoFH is very rare and associated with many cardiovascular complications that can be fatal. The medical treatment of HoFH is rarely sufficient to manage the disease, and surgical interventions are eventually required. The outcomes of surgical treatment are generally good and acceptable.
