Insights

The coronary slow flow phenomenon (CSFP) is linked to hypertension, dyslipidemia, and tobacco use. These risk factors are independently associated with CSFP, indicating it

Area of Science:

  • Cardiology
  • Interventional Cardiology
  • Coronary Artery Disease

Background:

  • Coronary slow flow phenomenon (CSFP) is an angiographic finding of delayed distal vessel opacification without significant stenosis.
  • The exact causes of CSFP remain unclear despite being known for decades.

Purpose of the Study:

  • To determine the clinical, demographic, risk factor, and angiographic profile of patients with CSFP.
  • To identify factors associated with the development of CSFP.

Main Methods:

  • Consecutive patients undergoing coronary angiography between September 2016 and March 2017 were analyzed.
  • Patients with CSFP were compared to a control group with normal coronary flow (NCF).
  • CSFP diagnosis was based on the corrected thrombolysis in myocardial infarction frame count.

Main Results:

  • CSFP was more prevalent in males.
  • Hypertension, dyslipidemia, and tobacco use were significantly more common in CSFP patients.
  • Multivariable analysis revealed hypertension, dyslipidemia, smoking, and tobacco chewing as independent risk factors for CSFP.
  • Acute coronary syndrome (ACS) was the most frequent presentation in CSFP patients.

Conclusions:

  • CSFP is common in patients presenting with ACS.
  • Hypertension, dyslipidemia, smoking, and tobacco chewing are independent risk factors for CSFP.
  • CSFP should be regarded as a pathological entity, not a benign condition.

Factors Affecting the Risk of Infection01:26

Factors Affecting the Risk of Infection

The hosts' susceptibility to infection depends on several factors. The integrity of the skin and mucous membranes helps protect the body against microbial attacks. When the skin is altered, the chance of infection, limb loss, and even death increases.
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin...

Tip-of-the-Tongue Phenomenon

The tip-of-the-tongue (TOT) phenomenon is a cognitive experience characterized by a temporary inability to retrieve specific information from memory despite having a strong feeling of knowing the information. Although individuals cannot access the target word or detail, they frequently recall related elements, such as its initial letter, syllable count, or context. This partial retrieval often causes frustration, as one might recognize a familiar face or know that a name starts with a specific...

Gene Evolution - Fast or Slow?

The genomes of eukaryotes are punctuated by long stretches of sequence which do not code for proteins or RNAs. Although some of these regions do contain crucial regulatory sequences, the vast majority of this DNA serves no known function. Typically, these regions of the genome are the ones in which the fastest change, in evolutionary terms, is observed, because there is typically little to no selection pressure acting on these regions to preserve their sequences.
In contrast, regions which code...

Acute Coronary Syndrome II: Pathophysiology and Clinical Manifestations

The pathophysiology of Acute Coronary Syndrome [ACD] involves several key processes:The main underlying cause of ACD is atherosclerosis, a chronic inflammatory disease characterized by the buildup of lipid-laden plaques within the coronary arteries.As the atherosclerotic plaque grows in the coronary artery, it may become unstable due to the formation of a lipid-rich core and a thin fibrous cap. Inflammatory cells within the plaque, such as macrophages, secrete enzymes that degrade the...

Coronary Artery Disease III: Clinical Manifestations

Coronary Artery Disease (CAD) is a primary health risk worldwide, leading to significant morbidity and mortality. The condition arises from the buildup of atherosclerotic plaques within the coronary arteries, resulting in diminished blood supply to the heart muscle.The clinical manifestations of CAD vary widely, from asymptomatic stages to severe, life-threatening conditions. Understanding these manifestations is crucial for early diagnosis and effective management.Angina Pectoris: The Warning...
