Facilitated advancement of the Palmaz-Schatz stent delivery system with the use of an adjacent 0.018′ stiff wire
The 5.0 French Palmaz-Schatz stent delivery system is a relatively bulky, stiff system which can be advanced only over a 0.014′ wire. Although crossing failure is rare, advancement of the delivery system through tortuous, rigid vessels may be unsuccessful. We report on four consecutive cases in which the initial advancement of the Palmaz-Schatz stent delivery system was unsuccessful due to vessel tortuosity or vessel angulation. The use of a 0.018′ stiff wirer adjacent to the Palmaz-Schatz delivery system, to “straighten” the vessels and to give additional guide catheter support, allowed for the successful advancement and delivery of coronary stents in all four cases. © 1996 Wiley-Liss, Inc.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/38223/1/24_ftp.pd
Gender Differences and Cardiometabolic Risk: The Importance of the Risk Factors
Metabolic syndrome (Mets) is a clinical condition characterized by a cluster of major risk factors for cardiovascular disease (CVD) and type 2 diabetes: proatherogenic dyslipidemia, elevated blood pressure, dysglycemia, and abdominal obesity. Each risk factor has an independent effect, but, when aggregated, they become synergistic, doubling the risk of developing cardiovascular diseases and causing a 1.5-fold increase in all-cause mortality. We will highlight gender differences in the epidemiology, etiology, pathophysiology, and clinical expression of the aforementioned Mets components. Moreover, we will discuss gender differences in new biochemical markers of metabolic syndrome and cardiovascular risk
Sustainability of the Mediterranean Diet: A Nutritional and Environmental Imperative
Sustainability is increasingly recognized as a key determinant of public health, influencing environmental quality, food security, and long-term well-being. The Mediterranean Diet (MedD) is widely recognized for its health-promoting properties, particularly in the prevention of cardiovascular and metabolic diseases. In recent years, increasing attention has been given to its role in environmental sustainability. This manuscript explores the MedD through a multidisciplinary lens, integrating nutritional science with ecological and socio-economic considerations. The MedD’s low environmental footprint, emphasizing its reduced greenhouse gas emissions, efficient land and water use, promotion of biodiversity, and minimization of food waste. These characteristics position the MedD as a model dietary pattern aligned with the principles of sustainable development.
However, the traditional MedD is facing significant challenges, including the globalized food market, urbanization, climate change, and shifting consumer behaviors, particularly among younger populations. These dynamics threaten both adherence to the diet and the sustainability of its core components. By framing the MedD as both a cultural heritage and a forward-looking strategy, we propose it as a valuable template for achieving global health and sustainability goals. This work calls for renewed commitment to preserving and adapting the Mediterranean Diet in contemporary food systems

Obstructive sleep apnea syndrome (OSAS) in women: A forgotten cardiovascular risk factor
Sleep-disordered breathing is a highly prevalent disorder with negative impact on healthcare systems worldwide. This condition has detrimental effects on cardiovascular health and quality of life, and is frequently associated with a variety of comorbidities, including cardiovascular disease, heart failure, diabetes and atrial fibrillation. Nevertheless, it remains frequently undiagnosed and undertreated, especially in specific populations. Studies on sleep-disordered breathing have been conducted mainly on male patients, and the prevalence and severity of this disorder in women are underestimated. Recently, some clinical and laboratory evidence has highlighted the epidemiological and pathophysiological differences between men and women with sleep-disordered breathing. In this review, we discuss sex-related mechanisms of sleep-disordered breathing in frequently associated disorders, to improve clinical understanding of this condition and to simplify the practical application of targeted interventions. The aim is to improve prognosis among female patients and guarantee a better quality of life and a reduction in healthcare cost
A matter of sex—persistent predictive value of MECKI score prognostic power in men and women with heart failure and reduced ejection fraction: a multicenter study
Background: A sex-based evaluation of prognosis in heart failure (HF) is lacking. Methods and results: We analyzed the Metabolic Exercise test data combined with Cardiac and Kidney Indexes (MECKI) score registry, which includes HF with reduced ejection fraction (HFrEF) patients. A cross-validation procedure was performed to estimate weights separately for men and women of all MECKI score parameters: left ventricular ejection fraction (LVEF), hemoglobin, kidney function assessed by Modification of Diet in Renal Disease, blood sodium level, ventilation vs. carbon dioxide production slope, and peak oxygen consumption (peakVO2). The primary outcomes were the composite of all-cause mortality, urgent heart transplant, and implant of a left ventricle assist device. The difference in predictive ability between the native and sex recalibrated MECKI (S-MECKI) was calculated using a receiver operating characteristic (ROC) curve at 2 years and a calibration plot. We retrospectively analyzed 7,900 HFrEF patients included in the MECKI score registry (mean age 61 ± 13 years, 6,456 men/1,444 women, mean LVEF 33% ± 10%, mean peakVO2 56.2% ± 17.6% of predicted) with a median follow-up of 4.05 years (range 1.72–7.47). Our results revealed an unadjusted risk of events that was doubled in men compared to women (9.7 vs. 4.1) and a significant difference in weight between the sexes of most of the parameters included in the MECKI score. S-MECKI showed improved risk classification and accuracy (area under the ROC curve: 0.7893 vs. 0.7799, p = 0.02) due to prognostication improvement in the high-risk settings in both sexes (MECKI score >10 in men and >5 in women). Conclusions: S-MECKI, i.e., the recalibrated MECKI according to sex-specific differences, constitutes a further step in the prognostic assessment of patients with severe HFrEF
Has the frequency of bleeding changed over time for patients presenting with an acute coronary syndrome? The Global Registry of Acute Coronary Events
AIMS: To determine whether changes in practice, over time, are associated with altered rates of major bleeding in acute coronary syndromes (ACS). METHODS AND RESULTS: Patients from the Global Registry of Acute Coronary Events were enrolled between 2000 and 2007. The main outcome measures were frequency of major bleeding, including haemorrhagic stroke, over time, after adjustment for patient characteristics, and impact of major bleeding on death and myocardial infarction. Of the 50 947 patients, 2.3% sustained a major bleed; almost half of these presented with ST-elevation ACS (44%, 513). Despite changes in antithrombotic therapy (increasing use of low molecular weight heparin, P < 0.0001), thienopyridines (P < 0.0001), and percutaneous coronary interventions (P < 0.0001), frequency of major bleeding for all ACS patients decreased (2.6 to 1.8%; P < 0.0001). Most decline was seen in ST-elevation ACS (2.9 to 2.1%, P = 0.02). The overall decline remained after adjustment for patient characteristics and treatments (P = 0.002, hazard ratio 0.94 per year, 95% confidence interval 0.91-0.98). Hospital characteristics were an independent predictor of bleeding (P < 0.0001). Patients who experienced major bleeding were at increased risk of death within 30 days from admission, even after adjustment for baseline variables. CONCLUSION: Despite increasing use of more intensive therapies, there was a decline in the rate of major bleeding associated with changes in clinical practice. However, individual hospital characteristics remain an important determinant of the frequency of major bleeding
Mediterranean diet impact on cardiovascular diseases: a narrative review
: Cardiovascular disease (CVD) accounts for more than 17 million deaths per year worldwide. It has been estimated that the influence of lifestyle on CVD mortality amounts to 13.7% for smoking, 13.2% for poor diet, and 12% for inactive lifestyle. These results deeply impact both the healthy status of individuals and their skills in working. The impact of CVD on productivity loss accounts for the 24% in total costs for CVD management.Mediterranean diet (MedD) can positively impact on natural history of CVD. It is characterized by a relatively high consumption of inexpensive and genuine food such as cereals, vegetables, legumes, nuts, fish, fresh fruits, and olive oil as the principal source of fat, low meat consumption and low-to-moderate consumption of milk, dairy products, and wine.Its effects on cardiovascular health are related to the significant improvements in arterial stiffness. Peripheral artery disease, coronary artery disease, and chronic heart failure are all positively influenced by the MedD. Furthermore, MedD lowers the risk of sudden cardiac death due to arrhythmias.The present narrative review aims to analyze the effects of MedD on CVD
