Aneurysm II: Clinical Manifestations and Diagnostic Studies

127
Thoracic, aortic arch and abdominal aneurysms are significant vascular conditions that can present with various clinical manifestations and lead to serious complications. Understanding these manifestations and the appropriate diagnostic studies is essential for effective management and treatment.Thoracic Aortic AneurysmsThoracic aortic aneurysms often remain asymptomatic until they reach a size that impinges on adjacent structures. They typically cause deep, diffuse chest pain that radiates to...

Coronary Artery Disease I: Introduction

771
Coronary Artery Disease (CAD): An Overview with Scientific InsightsCoronary Artery Disease (CAD), often referred to as C-A-D, is a prevalent blood vessel disorder classified under the broader category of atherosclerosis. Atherosclerosis is a pathological process characterized by the hardening and narrowing of arteries due to the accumulation of atherosclerotic plaques. These plaques are composed of cholesterol, fatty substances, inflammatory cells, calcium, and fibrin, reducing blood flow to...

Aortic Regurgitation I: Introduction

309
IntroductionAortic regurgitation is characterized by the backward flow of blood from the aorta into the left ventricle during diastole and arises from the improper closure of the aortic valve. This condition results in left ventricular volume overload and can stem from both acute and chronic etiologies, each contributing uniquely to the disease's progression and symptomatology.Acute and Chronic CausesAcute aortic regurgitation often results from events that suddenly impair the integrity of the...

Aortic Regurgitation II: Clinical Features and Diagnostic Tests

273
Aortic valve regurgitation (AR) occurs when the aortic valve fails to close properly, allowing blood to flow backward from the aorta into the left ventricle. This backflow can result in two distinct clinical presentations: acute and chronic AR, each characterized by its own set of symptoms and physical findings.Acute Aortic RegurgitationAcute AR presents with a sudden onset of severe symptoms. Patients typically experience profound dyspnea (shortness of breath), chest pain, and signs of left...

Aneurysm I: Introduction

198
An aortic aneurysm is a localized outpouching or dilation at a weak point in the artery wall. It may involve different parts of the aorta, such as the abdominal aorta, aortic arch, or thoracic aorta.Etiological factorsSeveral disorders are associated with aortic aneurysms.Congenital causes, such as primary connective tissue disorders like Marfan syndrome, impact the integrity and strength of connective tissues, notably affecting the aorta. Marfan syndrome is a genetic disorder that specifically...

Aortic Regurgitation III: Medical Management

259
Aortic regurgitation (AR) is when the aortic valve does not close or seal properly, leading to backward blood circulation from the aorta into the left ventricle during diastole. Common causes of AR include rheumatic heart disease, congenital valve defects, and aortic root dilation. Managing AR requires a multifaceted approach to alleviate symptoms, preserve left ventricular function, and address the underlying cause of the regurgitation. Patients with symptomatic AR or significant left...

Area of Science:

  • Cardiology
  • Epidemiology
  • Geriatrics

Background:

  • Aortic stricture (AS) is a prevalent cardiovascular disease in individuals aged 65 and older.
  • Epidemiological studies suggest associations between cardiovascular risk factors (CRFs) and comorbidities with AS.

Purpose of the Study:

  • To evaluate the association between CRFs and comorbidities with severe symptomatic AS in older adults (≥65 years).
  • To identify specific risk factors and comorbidities that increase the likelihood of severe AS in this demographic.

Main Methods:

  • An epidemiological case-control study was conducted.
  • Data on CRFs and comorbidities were collected from a primary care center.
  • Adjusted odds ratios (OR) and multiple logistic regression models were used to determine associations.

Main Results:

  • The study included 102 cases and 221 controls (mean ages 77.6 and 75.5 years, respectively).
  • Significant CRFs for severe symptomatic AS included hypercholesterolemia (OR, 2.67), tobacco use (OR, 2.60), hypertension (OR, 2.41), and low HDL cholesterol (OR, 2.20).
  • Significant comorbidities included carotid stenosis (OR, 14.5), stroke (OR, 4.14), chronic renal failure (OR, 3.78), and low hemoglobin levels (OR, 0.76).

Conclusions:

  • Hypercholesterolemia, tobacco use, arterial hypertension, and low HDL cholesterol are key CRFs associated with increased risk of severe AS.
  • Comorbidities such as chronic renal failure, stroke, carotid stenosis, and low hemoglobin levels are significantly associated with AS and may serve as potential markers.
