Is the prevalence of risk factors, clinical presentations and severity of coronary artery diseases (CAD) in patients with very early and premature CAD are different from mature CAD patients?: A registry- based cross-sectional study

IntroductionThe present study aims to compare the risk factors, clinical presentation, and severity of coronary artery involvement in young compared to elderly CAD patients to assess the cardiovascular health status for better disease management and control of these specific patients. MethodsThis registry-based cross-sectional study was conducted using Coronary Angiography and Angioplasty Registry (CAAR) patients in east of Tehran, Iran. The data were extracted from 330 patients with confirmed CAD recorded by the CAAR during July 2021 to August 2023. ResultsThe majority of patients in MCAD (68.2%) and VECAD (80%) were male, while the majority of PCAD patients were female (51.8%). Among PCAD patients, the prevalence of diabetes (38.1%) was higher than in other groups. The presence of IHD history in the father (38.1%) and mother (26.3%) was higher in the VECAD group. The mean total cholesterol, LDL, and LDL/HDL ratio were higher in the VECAD group. Among MCAD group (75.4%) compared to PCAD (58.1%) and VECAD (47.2%) groups, the multi-vessel disease was more common.MCAD patients had the highest median Gensini score compared to PCAD and VECAD patients. Also, in male compared to female the mean Gensini score was higher by 8 units (ß = 8.26, 95%CI = 0.24, 16.28). ConclusionModifiable risk factors in young CAD patients are common. High LDL-C levels and smoking were the common modifiable CVD risk factors in young patients, indicating the significant role of these traditional risk factors in early atherosclerosis development alongside inheritable risk-factors such as positive family history that were more common in young CAD patients. While, the severity of coronary artery involvement in individuals with MCAD was higher, but the priority of involvement based on the type of vessel was almost the same in all CAD groups.

Associations and attributable burden between risk factors and all-cause and cause-specific mortality at different ages in patients with hypertension.

It remains unclear the age-specific associations of risk factors with deaths and mortality burden attributable across age. In a territory-wide retrospective cohort, 1,012,228 adults with hypertension were identified. Comorbidities including diabetes, chronic kidney disease (CKD), cardiovascular disease (CVD), heart failure, and cancer, and risk factors including current smoking and suboptimal control of blood pressure (BP), glucose and low-density lipoprotein cholesterol were defined. Associations of comorbidities/risk factors with all-cause and cause-specific mortality across age groups (18-54, 55-64, 65-74, and ≥75 years) were assessed. Population attributable fractions were also quantified. During a median follow-up of 10.7 years, 244,268 (24.1%) patients died, with pneumonia (7.2%), cancer (5.1%), and CVD (4.2%) being the leading causes. Despite increasing deaths with age, relative risk of mortality related to comorbidities/risk factors decreased with age; similar patterns were found for cause-specific mortality. The assessed risk factors accounted for 24.0% (95% CI 22.5%, 25.4%) deaths, with highest proportion in the youngest group (33.5% [28.1%, 38.5%] in 18-54 years vs 19.4% [17.0%, 21.6%] in ≥75 years). For mortality burden, CKD was the overall leading risk factor (12.7% [12.4%, 12.9%]) with higher proportions in older patients (11.1-13.1% in ≥65 years), while diabetes was the leading risk factor in younger patients (15.9-13.5% in 18-54 years). The association of comorbidities or risk factors with mortality is stronger in younger patients with hypertension, despite lower absolute mortality in young patients than in the elderly. Leading risk factors differed across age, highlighting the importance of targeted and precise risk management.

Lymphatic spread patterns in young versus elderly patients with stage III colon cancer.

The anatomical pattern of lymph nodes spread differs between young (aged 45 years or younger) and elderly (aged 80 years or older) patients with stage III colon cancer and is poorly investigated. Two groups of patients (young and elderly) with stage III colon cancer who underwent upfront extensive (D3) lymphadenectomy at eight Japanese centres between 1998 and 2018 were retrospectively analysed. The primary endpoint was the proportion of positive central lymph nodes. The lymph nodes spreading pattern and its prognostic impact on recurrence-free survival and overall survival in the two groups were also compared. Two hundred and ten young patients and 348 elderly patients were identified and compared. The total number of lymph nodes harvested and the total number of invaded lymph nodes were significantly higher in younger patients compared with elderly patients (median of 31.5 (3-151) versus 21 (3-116), P < 0.001 and median of 3 (1-21) versus 2 (1-25), P < 0.001 respectively). The proportion of positive central lymph nodes were higher in younger patients than in elderly patients (9.52% (95% c.i. 6.24 to 14.2%) versus 4.59% (95% c.i. 2.84 to 7.31%), P = 0.012). In multivariate models for recurrence-free survival, central lymph nodes invasion were identified as a poor prognostic factor in younger patients (HR 5.21 (95% c.i. 1.76 to 15.39)) but not in elderly patients (HR 1.73 (95% c.i. 0.80 to 3.76)). Young patients with stage III colon cancer have a higher risk of central lymph nodes invasion, suggesting a more aggressive disease biology. The presence of central lymph nodes invasion are associated with a worse outcome in young patients.

Metastasis patterns and prognosis in young gastric cancer patients: A propensity score‑matched SEER database analysis.

Whether young patients with metastatic gastric cancer (GC) had distinct metastasis patterns and survival outcomes from older patients remains controversial. The aim of the present study was to explore the metastasis patterns and prognostic factors in young patients and evaluate the survival outcome in comparison to their older counterparts. We identified patients with metastatic GC in the surveillance, epidemiology, and end results (SEER) database from 2010 to 2015. The patients were divided into two groups based on age at diagnosis: younger (≤40 years old) and older (>40 years old). We employed the chi-squared test to compare the clinicopathological characteristics between the two age groups. Furthermore, we conducted survival analyses using Kaplan-Meier and Cox regression analyses. To balance disparities in baseline characteristics, we employed propensity score matching (PSM). We identified 5,580 metastatic GC patients from the SEER database, with 237 (4.2%) classified as younger and 5343 (95.8%) as older patients. A total of 237 pairs of patients were generated after adjustment by PSM. Patients in the younger group exhibited a higher proportion of bone-only metastases and a lower proportion of liver-only metastases compared with patients in the older group. Multivariate Cox regression analysis demonstrated that youth was an independent protective factor for overall survival (OS) before and after PSM, but not for gastric cancer-specific survival (GCSS). Among the younger group, patients with liver-only metastasis demonstrated the best prognosis, whereas patients with lung-only metastasis exhibited significantly worse survival outcomes compared with liver-only metastases, even comparable to that of bone metastasis. Compared with the older group, the metastatic GC patients in the younger group exhibited more aggressive tumors but better prognoses. The metastasis pattern and its effect on the prognosis of GC varied by age group.

Mental health disorders as a risk factor in young patients with rectal prolapse.

Rectal prolapse (RP) typically presents in the elderly, though it can present in younger patients lacking traditional risk factors. The current study compares medical and mental health history, presentation, and outcomes for young and older patients with RP. This is a single-center retrospective review of patients who underwent abdominal repair of RP between 2005 and 2019. Individuals were dichotomized into two groups based on age greater or less than 40years. Of 156 patients, 25 were < 40. Younger patients had higher rates of diagnosed mental health disorders (80% vs 41%, p < 0.001), more likely to take SSRIs (p = .02),SNRIs (p = .021), anxiolytics (p = 0.033), and antipsychotics (p < 0.001). Younger patients had lower preoperative incontinence but higher constipation. Both groups had low rates of recurrence (9.1% vs 11.6%, p = 0.73). Young patients with RP present with higher concomitant mental health diagnoses and represent unique risk factors characterized by chronic straining compared to pelvic floor laxity.

Традиционные и нетрадиционные факторы риска развития инфаркта миокарда в молодом возрасте

In a world that is constantly changing, the emergence of certain diseases, such as cardiovascular disorders (CVD), is also changing. It is evident that there are unique characteristics of premorbid background, risk factors, pathogenesis, and course of CVD in young individuals compared to older individuals. Currently, there are no effective measures for primary prevention of CVD in young patients, and the use of risk-metric resources is limited due to their focus on elderly patients. Traditional risk factors for CVD are typically used to create an objective patient profile and determine the appropriate diagnostic pathway Non-traditional risk factors may not be immediately apparent, but they also play a role in the development of cardiac disorders in young patients and should be taken into consideration. Physicians should exercise caution when considering both traditional and non-traditional risk factors in young patients with chest pain This may necessitate more detailed monitoring of the patient's condition Timely medical care and management of comorbidities can significantly improve prognosis and maintain work capacity, which is particularly important at a young age. A personalized approach to the management of young patients is required for all of these entities Therefore, the issue of cardiovascular disease in young patients is currently urgent KEYWORDS: myocardial infarction, young patients, traditional risk factors, non-traditional risk factors FOR CITATION: Karetnikova V.N., Neeshpapa A.G., Peganova Kh.A. Traditional and non-traditional risk factors for myocardial infarction in young adults. Russian Medical Inquiry. 2024;8(1):26–30 (in Russ.). DOI: 10.32364/2587-6821-2024-8-1-4.

Risk Factor Profile and Hospital Outcomes in Patients ≤ 45 Years vs. &gt;45 Years of Age Presenting with Acute ST-Segment Elevation Myocardial Infarction

Objectives: In Pakistan, cardiovascular risk factors for acute myocardial infarction are increasing. There are few studies available on atherosclerotic risk factors in young patients and its outcome The purpose of this study was to compare pattern of traditional CVD risk factors, hospital mortality and major adverse cardiac events at discharge in young versus old patients (≤45years and above 45 years age respectively) admitted with STEMI and undergoing primary PCI.&#x0D; Methodology: This retrospective cohort study was conducted on consecutive patients presenting with STEMI between June 2013 and June 2018 in a single centre cardiac only tertiary care setup. Institute’s registry is fashioned along and is affiliated with US NCDR. Patients with cardiac arrest or cardiogenic shock at arrival were excluded. MACE was defined as post PCI cardiac arrest or cardiogenic shock, heart failure, major bleed or hospital death. Models were built using stepwise forward logistic regression method.&#x0D; Results: Total of 5343 patients were admitted with STEMI during study period, after exclusion data of 1642 patients were analyzed. Among young patients, the frequency of the male gender, any tobacco use and family history of premature coronary artery disease were significantly higher (all p values &lt; 0.001). While in older STEMI patients frequency of heart failure, hypertension, prior myocardial infarction, diabetes mellitus ,abnormal creatinine clearance (&lt;90 mL/min/1.73 m²) , multi-vessel coronary disease, advanced Killip class and higher body mass index was more prevalent (all P&lt;0.001). Among young patients advanced Killip class and femoral access site(all P values &lt;0.001), diabetes mellitus (p=0.03), abnormal creatinine clearance(p=0.04),and left ventricular ejection fraction less than 40%(p=0.01), were more significant in-hospital mortality predictor whereas advanced Killip class, Left ventricular ejection fraction less than 40% male gender(p=0.04), diabetes mellitus(p=0.001),femoral access site(p=0.001), and Left ventricular ejection fraction less than 40% were more significant MACE predictors (all P&lt;0.001).&#x0D; Conclusion: There were no significant difference in hospital mortality and MACE among young versus old STEMI patients when adjusted for diabetes mellitus, abnormal creatinine clearance (&lt;90 mL/min/1.73 m²), multi-vessel coronary disease, advanced Killip class. Tobacco use is the main modifiable risk factors for young patients with STEMI. Surprisingly, being a woman and having a positive family history with premature coronary artery disease were protective.

Comparison of serum lipoprotein(a) levels in young and middle-aged patients presenting for the first time with ST-elevation myocardial infarction: a single-centre study.

Lipoprotein(a) [Lp(a) ] is associated with coronary artery disease due to its atherogenic and thrombogenic nature. In this study, we aimed to compare the level of Lp(a) in young and middle-aged patients with ST-elevation myocardial infarction (STEMI). This retrospective study included 287 patients aged 20-65 years who presented to the emergency department for the first time due to STEMI. The patients were divided into two groups: 20-45 years (young group, n = 111) and 46-65 years (middle-aged group, n = 176). The groups were compared in terms of demographic characteristics, co-morbidities and laboratory findings. In the young group, smoking (99, 89.2% vs 130, 73.9%; p = 0.001), family history of coronary artery disease (75, 67.6% vs 80, 45.5; p < 0.001), serum Lp(a) level [38.1 ± 27.9 (93 ± 68) vs 23.5 ± 23.2 mg/dl (57 ± 56 nmol/l); p < 0.001], triglyceride level [219.1 ± 231.9 (2.48 ± 2.62) vs 170.2 ± 105.6 mg/dl (1.92 ± 1.19 mmol/l); p = 0.018), ejection fraction (52.4 ± 6.1 vs 47.2 ± 7.7%; p = 0.004) and single-vessel disease (83, 74.8% vs 110, 62.5%; p = 0.031) were higher than in the middle-aged group. In multivariable logistic regression analyses, family history (OR: 2.073, 95% CI: 1.210-3.549; p = 0.008), low high-density lipoprotin cholesterol level (OR: 1.032, 95% CI: 1.003-1.062; p = 0.029) and Lp(a) elevation (OR: 1.981, 95% CI: 1.871-3.991; p < 0.001) were possible independent risk factors for STEMI in young patients. Lp(a) level was found to be a higher and a possible independent risk factor in young patients who presented with STEMI for the first time, compared to the middle-aged patient group. Lp(a) is a highly atherogenic molecule and it has been associated with stroke, heart failure, aortic stenosis, as well as coronary artery disease. Measurement of Lp(a) levels may be recommended in young patients with high cardiovascular risk.

Central retinal vein occlusion in young population: risk factors and outcomes.

ObjectiveTo evaluate the risk factors and outcomes of central retinal vein occlusion (CRVO) in young patients (&amp;lt; 40 years).MethodsIn this retrospective monocentric case series, we included young patients (&amp;lt;40 years) with CRVO. Patients’ medical files were analyzed focusing on demographic characteristics, suspected risk factors, ophthalmic work-up, visual acuity (VA), treatment, and outcomes.ResultsA total of 54 eyes of 52 patients were included. Central retinal vein occlusion was considered idiopathic in 13 patients (25%). The main risk factors identified were ocular hypertension (20.4%), inflammation (20.4%), high blood pressure (14.8%), and coagulation abnormality (11.1%). Final VA was lower in patients with high blood pressure and inflammation when compared to patients with no risk factor (p = 0.03 and 0.04, respectively). Intravitreal injections were needed in 23 eyes (42.6%) and 19 eyes (35.2%) received panretinal photocoagulation treatment.ConclusionCentral retinal vein occlusion is frequently associated with risk factors in young patients (75% of patients). In addition to the usual factors found in older patients, such as ocular hypertension and high blood pressure, coagulation abnormality and inflammation were also among the risk factors identified. Young patients with CRVO should be evaluated for the presence of risk factors and patients with high blood pressure or inflammatory findings should be followed carefully since they have a worse outcome.

Prognostic factors in young patients with ST-segment elevation myocardial infarction.

The prognostic factors of young patients aged ≤40 years with ST-segment elevation myocardial infarction (STEMI) remain unclear. This study explored risk factors that may affect the 1-year prognosis of young STEMI patients by analyzing patient data of baseline, clinical regimen, and secondary prevention. Baseline and clinical data were collected from 420 STEMI patients aged ≤40 years. One year of follow-up was performed to record and compare the differences in data between patients with and without adverse events. Binary logistic regression analysis with controls for confounding factors was used to evaluate prognosis-related independent factors. The overall incidence of cardiovascular adverse events was 15.95%. Comparison of the subgroups revealed that regardless of adjustment for confounding factors, prognoses of the patients were affected by the following factors: BMI, marital status, serum apolipoprotein(a) (ApoA) levels, number of diseased vessels, treatment regimen, compliance of secondary prevention, improvement of lifestyle, and adjusted comorbidities ( P < 0.05). Independent analysis of adverse events revealed that BMI, number of diseased vessels, and compliance of secondary prevention were independent factors of recurrent acute myocardial infarction in patients. Serum ApoA level, treatment regimen, and compliance of secondary prevention were independent influence factors of heart failure in patients. Marital status and serum ApoA level were independent factors of malignant arrhythmias in patients. BMI, compliance of secondary prevention, and improvement of lifestyle were independent factors of cardiac death in patients. This study determined the influential factors for the prognosis of STEMI patients aged ≤40 years as follows: BMI, marital status, comorbidities, number of diseased vessels, regimen, compliance of secondary prevention, and improvement of lifestyle. The risk of cardiovascular adverse events may be reduced by modulating the influential factors.

Procedural outcome and risk prediction in young patients undergoing transvenous lead extraction. A GALLERY subgroup analysis

Abstract Funding Acknowledgements Type of funding sources: None. Background The prevalence of young patients with cardiac implantable electronic devices (CIED) is continuously rising. Along with this development there is a concomitant increase in the incidence of CIED-related complications, such as device-related infections and lead failure. Transvenous lead extraction (TLE) has evolved into an indispensable therapeutic option for such cases. Aim The aim of this study was to analyze patient characteristics and procedural outcomes of young patients undergoing TLE and to identify independent risk factors for adverse events. Methods We performed a subgroup analysis of all patients in the GALLERY (GermAn Laser Lead Extraction RegistrY) who were 45 years or younger at the time of enrollment. Predictor variables for all-cause mortality, procedural complications and procedural failure were assessed via multivariate analyses. Results We identified 160 patients (6.3% of the GALLERY) aged 45 years or younger with a mean age of 35.3±7.6 years and 42.5% (n=68) female patients. Mean body mass index was 25.6±5.4 kg/m2 and the proportion of patient with highly reduced ejection fraction (LVEF &amp;lt;30%) was 11.3%. Comorbidities, such as arterial hypertension (AHT), diabetes mellitus (DM) and chronic kidney disease (CKD) were present in 23.8%, 6.3% and 5.0% of patients, respectively. Leading extraction indication was lead dysfunction in 51.3% of cases, followed by local infections in 20.6% and systemic infections in 16.9%. The most common device to be extracted were implantable cardioverter-defibrillators (ICD) with 52.5%. Mean number of leads per patient was 2.2±1.0. Median age of the oldest indwelling lead was 91.5 [54.75-137.5] months. Median procedural time was 88 [65-151.75] minutes. Overall complication rate was 3.8% with 1.9% minor and 1.9% major complications. Complete procedural success was achieved in 90.6% of cases. Clinical procedural success rate was 98.1%. Procedure-related mortality was 0.0%. All-cause in-hospital mortality was 2.5%, which was mainly due to septic shock. Multivariate analysis revealed CKD as independent predictor for all-cause mortality (OR: 51.48; 95% CI: 1.98-1340.0; p=0.018). Lead age ≥10 years (OR: 14.58, 95% CI: 1.36-156.2; p=0.027) was identified as sole independent risk factor for procedural complication. Conclusion Transvenous lead extraction in young patients is safe and effective with a procedure-related mortality rate of 0.0%. All-cause mortality was mainly driven by patients succumbing to CIED-related sepsis, despite successful extraction. Chronic kidney disease and lead age ≥10 years are relevant risk factors in young patients undergoing TLE.

Modifiable Risk Factors in Diagnosed Cases of Acute ST Elevation Myocardial Infarction in Young Patients Presenting at Tertiary Care Hospital in Peshawar

Objectives: The objective of this study was to determine the frequency of modifiable risk factors in young patients diagnosed with acute ST elevation myocardial infarction (STEMI). Methodology: A cross-sectional study was conducted at the cardiology department of Lady Reading Hospital, Peshawar. A total of 236 patients presented with acute STEMI, between 18 to 50 years of age of either gender were included. All the included patients were subjected to detailed history and clinical examination and modifiable risk factors were observed. Results: Out of 236 patients, 42 (18%) patients were in age range 18-30 years and 194 (82%) patients were in age range 31-50 years. Mean age was 42±9.77 years, 156 (66%) patients were male. In total, 90 (38%) patients had sedentary lifestyle, 45 (19%) patients had positive history of atrial fibrillation. More over 92 (39%) patients were diabetic, 153 (65%) patients were hypertensive, 99 (42%) patients were smokers, 73 (31%) patients had dyslipidaemia, and 64 (27%) patients were obese. Conclusion: It has been observed that modifiable risk factors were prevalent in a vast majority of the young patients presenting with acute STEMI. Among these, sedentary lifestyle, smoking, obesity, and metabolic risk factors such as diabetes and dyslipidaemia need immediate attention.

Nephrosclerosis in young patients with malignant hypertension.

Nephrosclerosis is one of the histopathological consequences of severe or malignant hypertension (MH), some of the pathophysiology of which has been extrapolated from essential polygenetic arterial hypertension. Despite our recent description of unsuspected ciliopathies with MH, causes of MH in young patients with severe renal impairment are poorly understood. To refine and better describe the MH phenotype, we studied clinical and prognostic factors in young patients receiving a kidney biopsy following their first episode of MH. Patients were identified retrospectively and prospectively from eight centres over a 35-year period (1985-2020). Keywords were used to retrospectively enrol patients irrespective of lesions found on renal biopsy. A total of 114 patients were included, 77 (67%) of whom were men, average age 34years, 35% Caucasian and 34% African origin. An isolated clinical diagnosis of severe nephrosclerosis was suggested in only 52% of cases, with 24% primary glomerulopathies. Only 7% of patients had normal renal function at diagnosis, 25% required emergency dialysis and 21% were eventually transplanted. Mortality was 1% at the last follow-up. Independent prognostic factors significantly associated with renal prognosis (6-month dialysis) and predictive of end-stage renal disease were serum creatinine on admission {odds ratio [OR] 1.56 [95% confidence interval (CI) 1.34-1.96], P<.001} and renal fibrosis >30% [OR 10.70 (95% CI 1.53-112.03), P=.03]. Astonishingly, the presence of any thrombotic microangiopathy lesion on renal biopsy was an independent, protective factor [OR 0.14 (95% CI 0.02-0.60), P=.01]. The histopathological hallmark of nephrosclerosis was found alone in only 52% of study patients, regardless of ethnicity. This suggests that kidney biopsy might be beneficial in young patients with MH.

Sulcus depth, congruence angle, Wiberg index, TT-TG distance, and CDI are strong predictors of recurrent patellar dislocation.

To characterize patellofemoral morphology, determine radiological cutoff values based on computed tomography (CT) images, and clarify predominant anatomic risk factors in young patients with recurrent patellar dislocation (RPD). A total of 212 knees (age 23.0 ± 5.3years, female: male = 110:102) with CT-confirmed RPD were enrolled for analysis. The control group was matched by age and sex (2:1). Patellofemoral and trochlear morphology, patellofemoral alignment, and other parameters were assessed by CT. Standardized methods were used for measurements. Receiver operating characteristic (ROC) curves and the areas under the ROC curve (AUCs) were used to assess accuracy in diagnosing RPD. The index of union (IU) was employed to identify a cutoff value for risk. A binary logistic regression model (Forward, LR) was constructed, and standardized coefficients were calculated to compare the relative strength of different predictors. Factors included in the model were employed to calculate distributions in the studied population. The majority of measurements showed a significant difference between the RPD and control groups when comparing mean values. The AUC value was favorable for sulcus depth and significantly better than that for other trochlear morphology parameters (P < 0.0001). Cutoff values were 0.58 for the Wiberg index, 153.3° for the sulcus angle, 3.6mm for the sulcus depth, 1.94 for the trochlear width ratio, 16.2° for the lateral trochlear inclination, 17.2° for the patellar lateral tilt, 25.5° for the congruence angle, 1.2 for the patellar height [Caton-Deschamps index (CDI)], 6.1° for the knee rotation, and 16.4mm for the tibial tubercle-trochlear groove (TT-TG) distance. A binary logistic regression model (χ2 = 20.826, P = 0.008) including the Wiberg index, sulcus depth, congruence angle, patellar height (CDI), and TT-TG distance was constructed for RPD (P ≤ 0.015), which showed excellent diagnostic performance, as indicated by an AUC of 0.989 (95% CI, 0.979 to 0.998). Sulcus depth showed the strongest relationship with RPD, followed by the congruence angle and Wiberg index, as indicated by the standardized coefficients -1.43, 1.02, and 0.97, respectively. Eighty-seven percent of the RPD population had sulcus depth ≤ 3.6mm. This study provides a systematic reference of cutoff values based on CT data. The combination of five anatomic risk factors (sulcus depth, congruence angle, Wiberg index, TT-TG distance, and CDI) may be an excellent predictor of RPD as initial risk assessment. Sulcus depth, as the most frequently observed anatomic risk factor, showed the best diagnostic performance among trochlear morphological parameters and the strongest relationship with RPD, followed by the congruence angle and Wiberg index. In clinical practice, the sulcus depth, congruence angle, Wiberg index, TT-TG distance, and CDI with the proposed cutoff values can be used in combination to evaluate RPD. When assessing trochlear morphology, sulcus depth is recommended as the best radiological parameter. Level III.

Strength of association of classical vascular risk factors in young patients with ischaemic stroke: a case-control study

IntroductionRecent studies have reported an increasing incidence of ischaemic stroke among young adults. However, the strength of the association between traditional vascular risk factors has not been fully established. MethodsWe compared 120 patients with a first ischaemic stroke before the age of 55 years admitted to the stroke unit of our centre with 600 healthy non-stroke controls from a population-based cohort study (HERMEX), matched for sex. Risk factors assessed included: hypertension, obesity, auricular fibrillation, current smoking, estimated glomerular filtration rate (eGFR), total cholesterol, low-density lipoprotein cholesterol (LDL-C), triglycerides, high-density lipoprotein cholesterol (HDL-C) and diabetes mellitus. We used logistic regression analysis and calculated population attributable risk. We performed an overall analysis, by sex and aetiological subgroup. ResultsUsing logistic regression analysis, we found that overall, the significant risk factors were: hypertension (OR: 1.58; 95%CI: 1.01-2.50), atrial fibrillation (OR: 4.77; 95%CI: 1.20-19.00), low eGFR (OR: 4.74; 95%CI: 1.3-21.94) and low HDL-C (OR: 5.20; 95%CI: 3.29-8.21), as well as smoking for males (OR: 1.86; 95%CI: 1.14-3.03). LDL-C showed an inverse association with stroke. The population attributable risk for HDL-C was 37.8% and for hypertension 21.1%. In terms of aetiological subgroups, only low HDL-C was associated with stroke of undetermined aetiology. ConclusionsHypertension, auricular fibrillation, low eGFR, and low HDL-C, plus tobacco use in men, are the main risk factors among patients under 55 years of age with a first ischaemic stroke. We believe that it would be of particular interest to further explore the management of low HDL-C levels as part of preventive strategies in young stroke patients.

Gastric cancer in young adults

Purpose: To analyse differences in clinicopathological features and prognosis between gastric cancer patients less than 40-year-old and older. Patients and Methods: Medical records of 299 cases of gastric carcinoma treated from January, 2016 through December, 2017 in Surgery Department No 2, HCMC Oncology Hospital were studied retrospectively. Results: Gastric cancer patients less than 40-year-old were 8.7% (95% CI: 5.5 - 11.9%). Compared to older patients, gastric cancer patients younger than 40 years: more frequently had grade 3 tumors (77% with grade 3 tumors vs 52%, p=0.013), had no difference in other clinicopathologic features, had an inferior median overall survival (5 vs 12 months, p=0.044). TNM stage was an independent prognostic factor in young patients with gastric cancer. For stage IV disease, young adults had overall survival 3.6 times less than older patients (p=0.019). Conclusion: Patients with young-onset gastric cancer were more likely to have grade 3 tumors. Yet, their other clinicopathological features were comparable to older patients. They had an inferior median overall survival Key words: gastric cancer, young adults

Ischemic stroke in young patients in Medellín, Colombia

BackgroundThere is scarce information about ischemic stroke in young patients in Colombia. To get insights about this phenomenon, this study describes the etiologies and risk factors of ischemic stroke in young patients in a third level complexity referral hospital in Medellin, Colombia.MethodsA retrospective observational cross-sectional study was carried out reviewing the medical records of patients between 18 to 49 years old admitted for the first time for ischemic stroke, from January 2009 to December 2019. The sociodemographic characteristics, risk factors, and etiological classification of ischemic stroke according to the Trial of Org 10,172 in Acute Stroke Treatment (TOAST) were described.ResultsTwo hundred thirty-seven cases were found. The most frequent risk factors were arterial hypertension (31.7%), smoking (29.5%) and alcohol intake (23.2%). There was a greater number of traditional cardiovascular risk factors at older ages. The TOAST classification was large-artery atherosclerosis (6.8%), cardioembolism (17.7%), small-vessel disease (7.6%), other determined etiology (25.7%) and undetermined (42.2%). Within cardioembolism, the most common high-risk source was valve replacement, and the most common moderate-risk source was patent foramen ovale. Craniocervical arterial dissection (11.4%) and substance abuse (2.9%) were the two most frequent sources within other determined etiologies. The most common compromised vascular territory was the anterior (55.7%).ConclusionsThe high frequency of traditional risk factors in young patients highlights the need to optimize primary and secondary prevention plans. This study provides new insights about the relevance of illicit substance abuse in Colombia as a cause of stroke in young patients, unlike the previous one conducted in Bogotá. Infectious causes were other peculiarities found. It is necessary to investigate the reasons for the high proportion of undetermined causes.

Cardiovascular risk factors in young patients presenting with STEMI in a city of South Europe

Background and Aims : The presence of ischaemic heart disease and Acute Coronary Syndromes (ACS) in young patients are becoming more frequent in our society nowadays. However, there is little information published about this population, especially in the area of South Europe, where we cannot find large series of young patients. Furthermore, there are socio-demographic differences between North and South Europe, which may have an influence over the prevalence of risk factors in this population. Our aim is to describe the prevalence of risk factors in one population of young patients admitted to our hospital with the diagnosis of ST elevation myocardial infarction (STEMI).

Validation of thrombotic risk factors in 1381 patients with essential thrombocythaemia: A multicentre retrospective real-life study.

Thrombosis and haemorrhage are frequent in patients with essential thrombocythaemia (ET). The 2016 revised International Prognostic Score for Thrombosis in Essential Thrombocythaemia-thrombosis (r-IPSET-t) score stratifies patients into very-low- (VLR), low- (LR), intermediate- (IR) and high-risk (HR) groups. We validated the r-IPSET-t in the biggest population of patients with ET (n=1381) to date and found it to be a better fit than the earlier IPSET-t score. With an average follow-up of 87.7 months, there were 0.578 thrombotic events/person-year and 0.286 bleeding events/person-year after diagnosis. The 10-year thrombosis-free survival was 88% and 99% for the r-IPSET-t LR and VLR groups (p < 0.001). Cytoreduction was a thrombotic risk factor in younger patients (aged <60 years, hazard ratio 9.49, p=0.026; aged ≥60 years, hazard ratio 1.04, p=0.93). In multivariable Cox regression analysis, anti-aggregation after diagnosis was protective for thrombosis (hazard ratio 0.31, p=0.005) but a risk factor for major bleeding (hazard ratio 10.56, p=0.021). Of the IPSET-t HR and LR groups, 132/780 and 249/301 were re-classified as LR and VLR respectively (p < 0.001). The European LeukemiaNET (ELN) does not recommend aspirin for VLR patients but in this real-life analysis 83.1% of VLR patients received it. Our results validate the r-IPSET-t score as more predictive for thrombosis than the ELN-recommended IPSET-t and raise concerns about unnecessary cytoreductive and anti-aggregative therapy.

Prevalence and risk of colorectal polyps among the Korean population under 50 years.

Colorectal cancer is a common cancer; generally, adults aged ≥ 50 years are screened using stool occult blood tests and colonoscopy. However, colorectal adenoma and cancer have been found in patients under the aged of 50, and studies on characteristics and risk factors in young patients are lacking. We evaluated the prevalence and risk factors of colorectal adenoma and cancer in young adults aged under 50 years.We retrospectively analyzed 570 individuals aged under 50 years who underwent colonoscopy at the Haeundae Paik Hospital, Korea, from January to June 2018. Logistic regression model was used to identify the risk factors for colorectal adenoma and colorectal cancer.The prevalence of colorectal adenoma in group of 19–29 years was 3.2% (1 of 31), 30–39 years was 13.8% (30 of 217) and in the group of 40–49 years was 21.1% (68 of 322) (P = .009). In multivariable analysis, age over 45 years (adjusted odds ratio [OR], 1.941; 95% confidence interval [CI], 1.187–3.172; P = .008) and male sex (adjusted OR, 1.711; 95% CI, 1.044–2.806; P = .033) were independent risk factors for colorectal neoplasia including cancer.The prevalence of colorectal adenoma increases as the age increased in young adults under 50 years of age, especially after the age of 45 years, the risk of colorectal neoplasia increases; hence, early screening should be considered before the age of 50 years.
