Insights

Psoriasis is not linked to major cardiovascular events in the short-to-medium term. This study found no significant association after accounting for other cardiovascular risk factors.

Area of Science:

  • Cardiology
  • Dermatology
  • Epidemiology

Background:

  • Psoriasis is a chronic inflammatory disease with potential systemic implications.
  • The relationship between psoriasis and major adverse cardiovascular events (MACE) requires further clarification.

Purpose of the Study:

  • To investigate the association between psoriasis and the risk of major cardiovascular events.
  • To determine if severe psoriasis increases cardiovascular risk.

Main Methods:

  • A cohort study included 48,523 patients with psoriasis and 208,187 controls.
  • Median follow-up was 5.2 years, with major cardiovascular events meticulously recorded.
  • Multivariable analysis adjusted for numerous cardiovascular disease risk factors.

Main Results:

  • The age- and gender-adjusted hazard ratios (HRs) for major cardiovascular events in psoriasis patients were 1.10 and 1.40 for severe psoriasis.
  • Fully adjusted HRs were attenuated to 1.02 for psoriasis and 1.28 for severe psoriasis.
  • Significant risk factors included inflammatory arthritis, diabetes, chronic kidney disease, hypertension, transient ischemic attack, atrial fibrillation, valvular heart disease, thromboembolism, congestive heart failure, depression, current smoking, age, and male gender.

Conclusions:

  • Psoriasis and severe psoriasis were not associated with an increased short-to-medium term risk of major cardiovascular events.
  • The association is attenuated after adjusting for established cardiovascular disease risk factors.
  • Further research may explore long-term cardiovascular outcomes in psoriasis patients.

Psychoneuroimmunology: Cardiovascular Disease

Psychoneuroimmunology (PNI) is a multidisciplinary field that examines how psychological factors, particularly stress, interact with the immune system and impact physical health. Research in PNI has shown that chronic or traumatic stress can disrupt both the hypothalamic-pituitary-adrenal axis and the sympathetic nervous system. These disruptions contribute to serious health conditions, including cardiovascular diseases.
A key area of focus in PNI is the relationship between stress and coronary...

Rheumatic Heart Disease II: Clinical Manifestations and Diagnostic Studies

The key clinical manifestations of Rheumatic heart disease (RHD) include several distinct cardiac symptoms.Carditis, a hallmark of acute rheumatic fever, involves inflammation of the heart's endocardium, myocardium, and pericardium. Chronic RHD often results from recurrent episodes of carditis. Its symptoms include the following:Murmurs are caused by valvular damage, especially to the mitral and aortic valves. Mitral stenosis or regurgitation is common, with characteristic heart murmurs...

Atherosclerosis III: Management

Management of atherosclerosis involves an integrated strategy encompassing pharmacological treatment, surgical interventions, lifestyle changes, and nutrition therapy to address the multifactorial nature of the disease.Pharmacological TherapyA cornerstone of atherosclerosis management is the use of pharmacological agents. Statins, such as atorvastatin, are pivotal in inhibiting HMG-CoA reductase, an enzyme that catalyzes an initial step in cholesterol synthesis in the liver. This reduction in...

Peripheral Arterial Disease II: Clinical Manifestations and Diagnostic Evaluation

Clinical manifestationsPeripheral Arterial Disease (PAD) manifests through a range of symptoms, from the characteristic intermittent claudication to atypical presentations and severe complications in advanced stages. Intermittent claudication, a hallmark symptom of PAD, presents as exercise-induced muscle pain that typically resolves within minutes of rest. This pain is reproducible and stems from inadequate blood flow, leading to the accumulation of lactic acid produced during anaerobic...

Coronary Artery Disease I: Introduction

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...

Rheumatic Heart Disease III: Medical Management

Rheumatic heart disease (RHD) management can be divided into two main strategies: prevention and long-term management.Primary PreventionPrimary prevention focuses on timely diagnosis and management of group A streptococcal pharyngitis to prevent acute rheumatic fever. The most widely used antibiotic for treating this condition is intramuscular benzathine penicillin G.Acute Rheumatic Fever TreatmentThe primary treatment goal for a patient diagnosed with acute rheumatic fever is to suppress the...
