CHA2DS2-VASc Score as a Predictor of Adverse Outcomes after Ischemic Stroke in Patients without Atrial Fibrillation.

BACKGROUND: Ischemic stroke is associated with increased risk of morbidity and mortality in future vascular events. OBJECTIVES: To investigate whether CHA2DS2-VASc scores aid in risk stratification of middle-aged patients without atrial fibrillation (AF) experiencing ischemic stroke. METHODS: We analyzed data of 2628 patients, aged 40-65 years with no known AF who presented with acute ischemic stroke between January 2020 and February 2022. We explored the association between CHA2DS2-VASc scores categorized by subgroups (score 2-3, 4-5, or 6-7) with major adverse cardiac and cerebrovascular events (MACCE) including recurrent stroke, myocardial infarction, coronary revascularization, or all-cause death during a median follow-up of 19.9 months. RESULTS: Mean age was 57 years (30% women); half were defined as low socioeconomic status. Co-morbidities included hypertension, diabetes, obesity, and smoking in 40-60% of the patients. The incidence rate of MACCE per 100 person-years was 6.7, 12.2, and 21.2 in those with score 2-3, 4-5, and 6-7, respectively. In a multivariate cox regression model, compared to patients with score 2-3 (reference group), those with score 4-5 and 6-7 had an adjusted hazard ratio (95% confidence interval [95%CI]) for MACCE of 1.74 (95%CI 1.41-2.14) and 2.87 (95%CI 2.10-3.93), respectively. The discriminative capacity of CHA2DS2-VASc score for overall MACCE was modest (area under curve 0.63; 95%CI 0.60-0.66), although better for myocardial infarction 0.69 (95% CI 0.61-0.77). CONCLUSIONS: CHA2DS2-VASc score may predict future MACCE in middle-aged patients with ischemic stroke and no history of AF.

[DOES INCIDENTAL CALCIUM DEPOSITION IN NON-CARDIAC CT SCANS PREDICT CARDIOVASCULAR MORBIDITY AND MORTALITY IN YOUNG ADULTS - A RETROSPECTIVE STUDY].

INTRODUCTION: Calcium score (CS) in cardiac CT scans represents an effective tool in the early diagnosis of cardiovascular disease. Few studies evaluated the value of incidental arterial calcification (AC) in non-cardiac CT scans, especially in young adults with no prior cardiovascular disease. AIMS: To examine the relationship between arterial calcifications and the incidence of cardiovascular events. METHODS: A retrospective study in patients aged 40-51 years old with no history of cardiovascular disease who underwent chest CT scans between 1.9.2012-31.8.2013 for reasons not related to cardiovascular disease. We assessed the presence of AC in the aorta and coronary arteries and its association with the rates of coronary catheterization for acute coronary syndrome (ACS), cardiac mortality and emergency room (ER) visits or hospitalizations for cardiovascular disease. Furthermore, we examined the association between AC and atherosclerotic risk factors. RESULTS: A total of 407 patients underwent CT scans for non-cardiovascular reasons within the timeframe specified; 308 were included in the study, 150 men and 158 women with average follow-up period of 7.2+0.29 years. There was an increased frequency in ACS and coronary catheterizations in patients with a positive AC compared to those with null AC (11.6% vs. 0.5% respectively, P= 0.0001, OR = 29.1). A positive AC was found more in men than women (35% vs. 20.9% respectively, P=0.006, OR=2.18). Patients with a positive AC had more ER and hospital admissions (33.7 % vs. 14.4% respectively, P<0.0001, OR=3). Patients with diabetes, hypertension and hyperlipidemia exhibited higher rates of positive AC. CONCLUSIONS: Although multivariate analysis is still to be conducted, it seems that AC is associated with cardiovascular morbidity and increased incidence of coronary catheterizations. Primary preventive strategies in patients with positive AC may reduce cardiovascular morbidity and mortality.

[AMIODARONE-INDUCED THYROTOXICOSIS - RISK FACTORS AND PREDICTORS OF OUTCOME: A RETROSPECTIVE STUDY].

BACKGROUND: Amiodarone induced thyrotoxicosis (AIT) occurs with considerable incidence and is associated with significant morbidity and mortality. Factors that predict poor prognosis in this disease have not yet been sufficiently investigated. OBJECTIVES: We examined the characteristics and short-term clinical outcomes of patients with AIT (up to six months from diagnosis). We evaluated the relationship between T3 and T4 levels at time of presentation and complications associated with AIT. METHODS: A retrospective epidemiological study was conducted reviewing all cases diagnosed with thyrotoxicosis and amiodarone consumption of patients treated in the Carmel Medical Center between the years 2004-2008. We examined the characteristics of patients who tend to develop AIT. In addition, we examined whether T3 and T4 levels at the time of presentation were a predictor of a poor prognosis. Three major complications associated with AIT were defined as primary outcomes within six months of diagnosis: 1. mortality; 2. development of AIT-related complications that required hospitalization; 3. the need for thyroidectomy. RESULTS: A total of 400 patients were diagnosed with thyrotoxicosis and consumed amiodarone. However, only 39 patients met the definition of AIT. The composite outcome of mortality, AIT-related complications and thyroidectomy were found in the vast majority of patients (94.8%, 37 out of 39 participants); 3 (7.6%) died and 35 (89.7%) were hospitalized with AIT-related complications and 8 (20.5%) required thyroidectomy. We found a statistically significant relationship between high T4 levels (above 64.3 mcg/dL or above 3 times the upper limit of the norm) and the composite of two main endpoints: mortality and the need for thyroidectomy in the first half year of diagnosis (P=0.009). CONCLUSIONS: AIT is associated with significant morbidity and mortality. An elevated level of free T4 reflects the severity of AIT. In patients with significantly increased T4 values, an early surgical intervention should be considered.

The alternative vagal maneuver; converting atrioventricular nodal re-entrant tachycardia by a rectal thermometer.

Vagal maneuvers are techniques used to increase parasympathetic tone, particularly useful in the management of hemodynamically stable supraventricular tachycardias. If ineffective, adenosine can be attempted. We present a patient with atrioventricular nodal re-entrant tachycardia (AVNRT), who could not effectively perform Valsalva maneuvers and had contraindications for carotid massage and adenosine administration, that converted into sinus rhythm by using a rectal thermometer. This maneuver was reproduced on various occasions. We suggest that rectal vagal maneuver may provide an additional therapeutic modality for selected patients with AVNRT.

Lipid-lowering therapy with inclisiran in the real-world setting: Initial data from a national health care service.

BACKGROUND: Inclisiran, a small-interfering RNA enabling long-term inhibition of PCSK9 synthesis, demonstrates good safety and efficacy profile in clinical trials. Real-world data on the potential to attain lipid-goals and reduce treatment gaps is lacking. OBJECTIVES: To investigate the implementation of inclisiran in real-world clinical setting. METHODS: Data from a nationwide healthcare organization on patients initiating inclisiran between 3/2022-11/2023. Patients' characteristics, lipid-lowering therapies, post-treatment reduction in low-density lipoprotein cholesterol (LDL-C), and attainment of treatment goals, were evaluated. RESULTS: Inclisiran was initiated by 503 patients (57 % women; mean age 66±11 years). Cardiovascular disease was present in 54 %, and peak LDL-C levels >190 mg/dL documented in 64 %. Prior exposure to PCSK9 monoclonal antibodies was evident in 28 %. Lipid profile >2 months after filling first prescription, was available in 397 patients (347 with ≥2 injections). In patients treated by inclisiran only (n = 254), median LDL-C reduction from peak levels was 57 % (IQR, 48 %-67 %), and from pre-injection levels 40 % (19 %-54 %). In those with concomitant lipid-lowering therapies (n = 143), median LDL-C reduction from peak levels was 66 % (IQR, 55 %-73 %), and from pre-injection levels 46 % (23 %-59 %). LDL-C < 70 mg/dL was attained by 39 % and LDL-C < 55 mg/dL by 21.9 %. Of those treated with concomitant statin therapy, 38 % attained LDL-C < 55 mg/dL. Overall, 6.5 % discontinued inclisiran therapy after initial injection. CONCLUSIONS: In real-world practice, inclisiran showed good efficacy in reducing LDL-C with high interindividual variability. However, attainment rates of lipid-goals were suboptimal due to limited use of combination lipid-lowering therapy and high-rates of severe hypercholesterolemia in our patient population cohort.

The interplay among body weight, blood pressure, and cardiorespiratory fitness in predicting atrial fibrillation.

BACKGROUND: Hypertension, obesity, and low cardiorespiratory fitness (CRF) are known risk predictors for the development of atrial fibrillation (AF) that often interrelate with each other. We examined the interplay of these 3 risk indicators with the occurrence of AF in patients without known cardiovascular disease. METHODS: A retrospective analysis of 13,042 patients underwent exercise stress testing (EST). The occurrence of AF during the median follow-up period of 6.8 years was investigated in relation to the presence of obesity (body mass index ≥30 kg/m2), hypertension (blood pressure ≥140/90 mmHg or history of hypertension), or low CRF (exercise capacity <8 metabolic equivalents). Cox proportional hazards models were used to evaluate the individual and combined association between the 3 risk indicators and AF. RESULTS: The mean age of the study population was 58 ± 9 years; 49% were women. AF occurred in 499 patients (3.8%). Obesity [hazard ratio (95% confidence interval)], 1.36 (1.12-1.65), hypertension, 1.47 (1.19-1.82), and low CRF, 1.32 (1.06-1.64), were independent risk predictors for AF after multivariable adjustment, including after adjusting for each other and also when the risk predictors were analyzed as continuous variables. In a combined model, a gradual increase in the risk of AF was observed, reaching an adjusted hazard ratio of 2.53 (1.77-3.62) in those with all 3 compared with neither risk indicators. P-for-interaction between hypertension and obesity, or hypertension and low CRF was nonsignificant. CONCLUSIONS: Obesity, low CRF, and hypertension are independently associated with an excess risk of developing AF in patients without known cardiovascular disease, both individually and more so when coexisting together.

Extreme lipoprotein(a) in clinical practice: A cross sectional study.

Introduction: Measurement of lipoprotein(a) [Lp(a)] is recommended once in a lifetime to identify individuals at high risk of atherosclerotic cardiovascular disease (ASCVD). We aimed to analyze the clinical features of patients with extreme Lp(a). Methods: Cross-sectional, case-control study of a single healthcare organization between 2015 and 2021. Individuals with extreme Lp(a) > 430 nmol/L (53 of 3900 tested patients) were compared to age- and sex-matched controls with normal range Lp(a). Results: Mean patient age was 58 ± 14 years (49% women). Myocardial infarction (47.2% vs. 18.9%), coronary artery disease (CAD) (62.3% vs. 28.3%), and peripheral artery disease (PAD) or stroke (22.6% vs. 11.3%) were more prevalent in patients with extreme than normal range Lp(a). The adjusted odds ratio [95% confidence interval (CI)] associated with extreme compared to normal range Lp(a) was 2.50 (1.20-5.21) for myocardial infarction, 2.20 (1.20-4.05) for CAD, and 2.75 (0.88-8.64) for PAD or stroke. A high-intensity statin plus ezetimibe combination was issued by 33% and 20% of CAD patients with extreme and normal range Lp(a), respectively. In patients with CAD, low density lipoprotein cholesterol (LDL-C) <55 mg/dL was achieved in 36% of those with extreme Lp(a) and 47% of those with normal range Lp(a). Conclusions: Extremely elevated Lp(a) levels are associated with an approximately 2.5-fold increased risk of ASCVD compared with normal range Lp(a) levels. Although lipid-lowering treatment is more intense in CAD patients with extreme Lp(a), combination therapies are underused, and attainment rates of LDL-C goals are suboptimal.

Gastric Dilatation Masquerading as Anterolateral ST-Elevation Myocardial Infarction.

A variety of noncardiac conditions mimic the electrocardiographic changes of ST-elevation myocardial infarction (STEMI). Therefore, a physician must maintain a high index of suspicion when evaluating ST-segment elevation (STE). We present a case of epigastric pain secondary to ileus and gastric dilatation masquerading as anterolateral STEMI on an electrocardiogram (ECG). The STE promptly resolved following laparotomy. To the best of our knowledge, this is the first case of anterolateral STE secondary to gastric dilatation.

Guideline-Directed Low-Density Lipoprotein Cholesterol Management After Acute Ischemic Stroke: Findings from a National Health Care Service.

Patients with ischemic stroke are at high risk for future cardiovascular events and should be treated intensively with lipid-modifying agents. Combination lipid-lowering therapies are often needed to achieve updated guideline-directed treatment goals. However, real-world data on intensification of lipid-lowering therapies and attainment of low-density lipoprotein cholesterol (LDL-C) targets early after ischemic stroke are limited. We extracted data from the largest healthcare provider in Israel on patients hospitalized with acute ischemic stroke between January 2020 and February 2022. Included were 3,027 patients surviving ≥1 year after stroke, with documented LDL-C levels and lipid-lowering medications at 2 time periods (0 to 3 months and 6 to 12 months after discharge). Participants were classified according to preexisting stroke and/or coronary artery disease. The use of combination lipid-lowering therapy (ezetimibe and/or proprotein convertase subtilisin/kexin type 9 [monoclonal antibodies] inhibitor plus statin) in the study population increased between the 2 timepoints from 3.6% to 5.1%, reaching 10.5% in those with previous coronary artery disease and stroke. LDL-C levels <70 and <55 mg/100 ml were attained by 42.3% and 22.9% of patients early after hospitalization, and in 49.5% and 27.1% during 6 to 12 months after hospitalization, respectively. Attainment of guideline-recommended LDL-C goals was higher in patients treated with combination lipid-lowering therapies and in those with preexisting cardiovascular disease. In conclusion, despite the advances in drug development and the availability of several mechanisms to lower cholesterol levels, the attainment of guideline-recommended LDL-C targets after acute ischemic stroke is suboptimal. Intensification of treatment with combination lipid-lowering therapies after hospitalization is uncommonly performed in clinical practice, even in those with preexisting cardiovascular disease.

A Patient With Single Coronary Artery and Pectus Excavatum Presenting With Non-ST Elevation Myocardial Infarction.

We report the case of a 51-year-old male with pectus excavatum (PEX) who presented with stress-related chest pain as a symptom of acute non-ST elevation myocardial infarction. Coronary angiography (CAG) revealed a suspected single coronary artery (SCA) anatomy with diffuse atherosclerotic narrowing, without evidence of other coronary ostia in the aortic root. The diagnosis was confirmed on cardiac computed tomography (CCTA) as the SCA of the R-I type by Lipton classification. The percutaneous coronary intervention was performed with good angiographic results and resolution of symptoms.

Cardiorespiratory Fitness and Risk of Cardiovascular Events and Mortality in Middle Age Patients without Known Cardiovascular Disease.

BACKGROUND: Low cardiorespiratory fitness is an established risk predictor for chronic non-communicable diseases. We aimed to investigate the prognostic significance of fitness level on the risk of major adverse cardiac events (MACE, the composite of myocardial infarction, stroke, or all-cause death), in a contemporary cohort of middle-aged subjects without cardiovascular disease. METHODS: Retrospective analysis of patients aged 40-60 years without a history of cardiovascular disease. Degree of fitness was determined according to a graded, maximal treadmill exercise stress testing (EST) time achieved, classified into age- and sex-specific quintiles (Q), and categorized as low (Q1), moderate (Q2-Q4) or high (Q5) fitness groups. A multivariable Cox proportional hazard regression model was used to assess the association of fitness level with the risk of MACE. RESULTS: A total of 6836 patients were included, of which 44.5% were women, and the mean age was 52 years. Overall, 289 MACE events occurred during a median follow-up of 7 years. Level of fitness was inversely associated with the presence of cardiovascular risk factors. The multivariable adjusted hazard ratio (95% confidence interval) for MACE was 1.65 (1.12-2.44) and 2.17 (1.40-3.38) in those at moderate and low fitness levels, compared to the high-fitness group (reference), respectively. For each decrease of one metabolic equivalent (MET) unit achieved at peak exercise, the relative risk for MACE increased by 18%. The association between low fitness and MACE was not modified by other risk factors (P-for-interaction non-significant). CONCLUSIONS: Low fitness level, as captured by a maximal treadmill EST, is an independent risk predictor for MACE among middle-age individuals without known cardiovascular disease. The association of low fitness with high burden of cardiometabolic risk factors highlight the importance of lifestyle intervention in this patient population.

Blood pressure measurements during treadmill exercise testing and the risk for the future development of atrial fibrillation.

Hypertension is a well-established risk factor for the onset and progression of atrial fibrillation (AF). Blood pressure (BP) measurements during routine exercise stress testing (EST) may identify subjects at increased risk for developing AF. We performed a retrospective analysis of treadmill EST carried out using the Bruce protocol in patients aged ≥40 years without a history of AF (n = 17,617; 42% women). BP was measured at rest, peak exercise, and 2-min recovery and analyzed for its association with the risk for developing AF. During a mean follow-up of 7 years, AF was documented in 4.5% of the patients. The incidence rate of AF per 1000 person-years increased with the rise in CHA2DS2VASc scores (3.26 for a Score=0 to 19.78 for scores ≥6). In a multivariate analysis, adjusting for risk score components and exercise capacity, systolic BP measurements taken at rest (≥130 vs. ≤110 mmHg), peak exercise (>170 vs. ≤150 mmHg), and recovery (>150 vs. ≤130 mmHg) were associated with an increased risk for AF: the hazard ratios (HRs) were 1.56 (95% CI, 1.30-1.87), 1.21 (1.01-1.45), and 1.33 (1.10-1.62), respectively. Similarly, diastolic BP measurements taken at rest (≥90 vs. <80 mmHg), peak exercise (≥100 vs. <90 mmHg), and recovery (>90 vs. ≤80 mmHg) were associated with an increased risk for AF: the HRs were 1.80 (1.36-2.38), 2.08 (1.28-3.37), and 1.56 (0.81-3.02), respectively. The association of exercise BP with AF was further observed when the BPs were analyzed as continuous variables and in subjects without a baseline diagnosis of hypertension. In conclusion, systolic and diastolic BP taken at the rest, peak exercise and recovery phases of EST may provide independent predictive information regarding future risk for developing AF.

Heart Rate Response to Exercise and Recovery: INDEPENDENT PROGNOSTIC MEASURES IN PATIENTS WITHOUT KNOWN MAJOR CARDIOVASCULAR DISEASE.

PURPOSE: Heart rate response during exercise testing (ET) provides valuable prognostic information. Limited data are available regarding the prognostic interplay of heart rate (HR) measured at rest, exercise and recovery phases of ET, and its ability to predict risk beyond exercise capacity. METHODS: Retrospective analysis of treadmill ETs was performed by the Bruce protocol in patients aged 35-75 yr without known cardiovascular disease (CVD; n = 13 887; 47% women). Heart rate recovery at 2 min (HRR2; defined abnormal <42 beats) and chronotropic index (CI; defined abnormal <80%, determined as age-predicted HR reserve) were analyzed in association with the risk of developing myocardial infarction, stroke, or death (major adverse cardiovascular event [MACE]) during median follow-up of 6.5 yr. RESULTS: The HRR2 <42 beats and CI <80% were each associated with increased risk of MACE: adjusted hazard ratios with 95% confidence interval 1.47: 1.27-1.72 and 1.66: 1.42-1.93, P < .001, respectively, evident also when analyzed as continuous variables. Strength of association of HRR2 and CI with outcome was attenuated but remained significant with further adjustment for exercise duration and metabolic equivalents. Having both HRR2 and CI abnormal compared with only one measure abnormal was associated with hazard ratios with 95% confidence interval of 1.66: 1.38-2.00 and 1.48: 1.22-1.79 for MACE, before and after adjustment for cardiorespiratory fitness (CRF). The degree of CRF (low vs mid/high) did not modify the prognostic effect of HRR2 and CI (P-for-interaction nonsignificant). CONCLUSIONS: Both HRR2 and CI provide independent prognostic information beyond CRF in patients without CVD referred for ET. The predictive ability is more pronounced when both abnormal HR measures coexist.

Blood pressure response during treadmill exercise testing and the risk for future cardiovascular events and new-onset hypertension.

OBJECTIVE: The physiologic response to exercise may provide valuable prognostic information. We investigated the association of blood pressure (BP) measurements during exercise stress testing (EST) with long-term risk of myocardial infarction, stroke or death (major adverse cardiovascular event, MACE), as well as the development of new-onset hypertension. METHODS: A retrospective analysis of treadmill ESTs (years 2005-2019) performed by the Bruce protocol in patients aged 35-75 years without a history of cardiovascular disease (n = 14 792; 48% women). BP was documented at rest, submaximal exercise (Bruce stage-2), peak exercise and recovery (2 min). Association of SBP measures with study outcomes during median follow-up of 6.5 years was investigated. RESULTS: Highest vs. lowest SBP quartile at rest (≥140 vs. <120 mmHg), submaximal-exercise (≥170 vs. <130 mmHg), peak-exercise (≥180 vs. ≤145 mmHg) and recovery (≥160 vs. <130 mmHg) was associated with an increase in the adjusted hazard ratio and 95% confidence interval (CI) for MACE: 1.53 (1.23-1.88), 1.33 (1.01-1.76), 1.30 (1.05-1.61), 1.35 (1.09-1.68), respectively. The association between SBP at submaximal exercise and recovery with MACE displayed a J-shaped pattern. Among nonhypertensive patients (n = 8529), excessive SBP response to peak exercise (≥190 mmHg in women and ≥210 mmHg in men) was an independent predictor of hypertension [hazard ratio (95% CI)]: 1.87 (1.41-2.48), as were SBPs during submaximal exercise [>160 vs. ≤130 mmHg: 2.44 (1.97-3.03)] and recovery [≥140 vs. ≤120 mmHg: 1.65 (1.37-1.98)]. CONCLUSION: BP measurement during rest, exercise and recovery phases of EST provides incremental prognostic information regarding long-term risk for cardiovascular events and the probability for developing hypertension.

Impact of glomerular filtration rate estimation on cardiovascular events in elderly patients undergoing coronary angiography.

BACKGROUND: Estimation of kidney function by glomerular filtration rate (eGFR) is affected by age and is important for decision making regarding treatment and prognosis of patients with cardiovascular disease. We investigated the impact of eGFR on long-term cardiovascular outcomes in an elderly population undergoing coronary angiography for evaluation or treatment of coronary artery disease. METHODS: GFR was estimated according to Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equation in 3690 elderly patients (aged 70-100 years) undergoing coronary angiography. Patients receiving maintenance dialysis were excluded. The association between eGFR and major adverse cardiovascular events (MACE) including myocardial infarction, ischemic stroke or death, was investigated. GFR was further calculated according to modification of diet in renal disease (MDRD) and the Cockcroft-Gault equations, and compatibility between estimations was analyzed. RESULTS: Cardiovascular comorbidities were more prevalent with the reduction in kidney function as was the proportion of patients presenting with acute coronary syndromes. The adjusted hazard ratio (95% confidence interval) for MACE during a mean follow-up of 5 years was 0.95 (0.77-1.16), 1.04 (0.84-1.29), 1.56 (1.16-1.84), 2.22 (1.65-2.97) and 3.74 (2.20-6.38) in patients with eGFR 60-89, 45-59, 30-44, 15-29 and <15 ml/min/1.73m2, respectively, compared to >90 ml/min/1.73m2. Reclassification of eGFR stages by MDRD (upward 23.8%, downward 0.4%) and Cockcroft-Gault (upward 4.3%, downward 28.1%) compared to CKD-EPI estimation, was noted. However, the association between eGFR stages and MACE was similar between equations. CONCLUSIONS: Kidney function, as manifested by eGFR, has a graded inverse association with the burden of cardiovascular comorbidities and long-term adverse events in elderly patients undergoing coronary angiography.

The Impact of Smoking Status 1 Year After ST-Segment Elevation Myocardial Infarction on Cardiovascular Events and Mortality in Patients Aged ≤60 Years.

Smoking is associated with increased risk for acute ST-elevation myocardial infarction (STEMI) at a young age. Although smoking is a modifiable risk factor, smoking cessation rates after STEMI are suboptimal. We investigated the association between smoking status 1 year after STEMI and adverse events in patients (n = 765) aged ≤60 years. Patients were categorized as: (1) nonsmokers, (2) quit smoking, and (3) continued/resumed smoking. The association between smoking status and risk for major adverse cardiovascular events (MACEs) was analyzed during a median follow-up of 8 years. At presentation with STEMI, the mean age was 51 ± 7 years (88% men) and 427 (56%) were smokers. A year after STEMI, 272 continued smoking, 35 quit but later resumed smoking (summed to a single group; n = 307), and 120 quit smoking. Continued smoking was associated with younger age, male gender, lower weight, and low socioeconomic status. Compared with nonsmokers, the adjusted hazard ratio (95% confidence interval) for myocardial infarction, stroke, unstable angina, death, and MACE was 2.51 (1.67 to 3.73), 2.07 (0.94 to 4.56), 3.73 (1.84 to 7.58), 2.52 (1.53 to 4.13), and 2.40 (1.80 to 3.22), accordingly, in those who continued to smoke. However, the adjusted hazard ratio was not significantly associated with these outcomes in patients who quit smoking (MACE: 1.20 [0.77 to 1.87], p=0.414; nonsignificant for individual end points). In conclusion, the prevalence of smoking in young and middle-aged patients presenting with STEMI is high and smoking cessation rates are low. A year after STEMI, those who continued to smoke had worse cardiovascular outcomes and death compared with nonsmokers; however, the long-term outcomes among those who quit smoking appear to be comparable with nonsmokers. The results highlight the contrast between health benefits of quitting smoking after STEMI and low abstinence rates in clinical practice.

Iliac Artery Rupture During Transfemoral Transcatheter Aortic Valve Implantation.

An 82-year-old male with severe symptomatic aortic stenosis underwent elective TAVR complicated by rupture of the proximal iliac artery. This case illustrates the feasibility of percutaneous vascular repair following severe vascular injury during TAVR.
