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.

Background: Several studies have shown that patients with fibromyalgia present with neuroendocrine, inflammatory, and coagulation features linked to cardiovascular disease development. However, the exact profile of cardiovascular risk factors and events in fibromyalgia remains to be defined.

Objectives: To compare the profile of cardiovascular risk factors and events between fibromyalgia outpatients and the general population in Italy.

Methods: Cardiovascular risk factors and events in fibromyalgia females were collected using the criteria adopted in the CUORE Project.

Results: The study comprised 62 female fibromyalgia patients and 4093 female controls from 35 to 75 years of age. The prevalence of hypertension, diabetes, atrial fibrillation, transient ischemic attack, and cardiovascular total burden was significantly higher in fibromyalgia females than in the general Italian population. No difference was found in blood fasting glucose, triglycerides, total and fractionated cholesterol levels, body mass index, and metabolic syndrome (MetS). The MetS rate was underestimated for methodological aspects.

Conclusions: Fibromyalgia is associated with an increased cardiovascular burden, probably through a specific risk factor profile.

Background: Several trials support the trans-radial route of percutaneous coronary intervention (PCI) since it reduces access site vascular complications and bleeding. 

Objectives: To examine the effects of trans-radial interventions (TRI) on clinical outcomes in a 'real world' cohort of patients undergoing PCI.

Methods: We analyzed 4873 consecutive patients who underwent PCI at a tertiary center and identified 373 patients who underwent TRI. Patients (radial vs. femoral) were compared using a propensity score analysis to best match between groups. Outcome parameters included total mortality, myocardial infarction (MI), repeat target vessel revascularization (TVR) rates, length of hospitalization and ∆Ht/Hb/creatinine values during hospitalization. These were evaluated at 6 months and 1 to 3 years after PCI.

Results: The rates of major adverse cardiovascular event (MACE) and its constituents were similar in the trans-radial vs. trans-femoral groups at all time intervals: 6.7% vs. 5.5% at 6 months, 10.3% vs. 10% at 1 year, 15.7% vs. 15% at 2 years, 15.7% vs. 16% at 3 years, respectively (P = 0.6). The length of hospitalization was shorter in the TRI group (2.87 days ± 2.04 vs. 3.3 days ± 3.12, P = 0.023). We did not find significant differences between the groups in the mean ∆Ht/Hb/creatinine values during the hospitalization course.

Conclusions: In a 'real-world' setting of PCI, the TRI route of PCI is as safe and efficient as the femoral approach. TRI is associated with shorter duration of hospitalization.

Background: Endothelial dysfunction is recognized as a major factor in the development of atherosclerosis and it has a prognostic value.

Objectives: To detect the long-term association of peripheral vascular endothelial function and clinical outcome in healthy subjects and patients with cardiovascular disease.

Methods: We prospectively assessed brachial artery flow-mediated dilation in 110 consecutive subjects (46 CVD[1] patients and 64 healthy controls), mean age 57 ± 11 years; 68 were men. After an overnight fast and discontinuation of all medications for ≥ 12 hours, percent improvement in FMD and nitroglycerin-mediated vasodilatation were assessed using high resolution ultrasound.

Results: %FMD[2] but not %NTG[3] was significantly lower in CVD patients (9.5 ± 8.0% vs. 13.5 ± 8.0%, P = 0.012) compared to healthy controls (13.4 ± 8.0% vs. 16.7 ± 11.0%, P = 0.084; respectively). In addition, an inverse correlation between %FMD and the number of traditional CVD risk factors was found among all study participants (r = -0.23, P = 0.015) and healthy controls (r = -0.23, P = 0.036). In a mean follow-up of 15 ± 2 months, the composite CVD endpoints (all-cause mortality, myocardial infarction, hospitalization for heart failure or angina pectoris, stroke, coronary artery bypass grafting and percutaneous coronary interventions) were significantly more common in subjects with FMD < 6% compared to subjects with FMD > 6% (33.3% vs. 12.1%, P < 0.03, respectively).
Conclusions: Thus, brachial artery %FMD provides important prognostic information in addition to that derived from traditional risk factor assessment

[1] CVD = cardiovascular disease

[2] %FMD = percent improvement in flow-mediated dilation

[3] %NTG = percent improvement in nitroglycerin-mediated vasodilatation
