Insights

Cardiovascular involvements are common in Chinese patients with hypereosinophilic syndrome (HES), leading to significant morbidity and mortality. Early detection and management of cardiac complications are crucial for improving patient outcomes in HES.

Area of Science:

  • Cardiology
  • Hematology
  • Internal Medicine

Background:

  • Hypereosinophilic syndrome (HES) is a rare disorder characterized by persistent eosinophilia.
  • HES can affect multiple organs, with cardiovascular involvement being a significant concern.

Purpose of the Study:

  • To investigate the prevalence and spectrum of cardiovascular involvements in Chinese patients diagnosed with HES.

Main Methods:

  • A retrospective review of 149 HES inpatients at Peking Union Medical College Hospital.
  • Analysis of clinical data, focusing on cardiovascular manifestations and outcomes.

Main Results:

  • Cardiac abnormalities were observed in 32.9% of patients.
  • Common involvements included ischemic changes, arrhythmias, myocardial injury, and thrombosis.
  • Poorer prognosis was associated with echocardiogram abnormalities compared to electrocardiogram findings alone.

Conclusions:

  • Cardiovascular complications are frequent and diverse in HES patients.
  • These complications represent a major cause of illness and death in HES.
  • Understanding these involvements is critical for patient management.

Heart Failure III: Clinical Manifestations

Heart failure (HF) manifests primarily as dyspnea, fatigue, and fluid retention, resulting in peripheral and pulmonary edema. Symptoms may vary depending on which ventricle is more affected, left or right.Left-Sided Heart FailureAlso known as left ventricular failure, this condition results from the left ventricle's inability to fill or eject sufficient blood into the systemic circulation. It leads to pulmonary congestion, which occurs when the left ventricle fails to eject blood effectively...
Asthma III: Clinical Manifestations01:13

Asthma III: Clinical Manifestations

Asthma presents with a characteristic pattern of episodic respiratory symptoms that reflect underlying airway inflammation, bronchoconstriction, and mucus hypersecretion. Although severity varies among individuals, certain clinical manifestations are considered hallmarks of the disorder and often guide diagnosis and assessment.Respiratory SymptomsA persistent cough is one of the most common early features of asthma. It is frequently dry and tends to worsen at night or in the early morning,...

Hypertension III: Clinical Manifestations and Diagnostic Studies

Hypertension is asymptomatic and also referred to as the "silent killer" until it progresses to a severe stage or causes target organ disease. Patients may experience symptoms stemming from the strain on blood vessels and tissues in various organs or the heart's increased workload.Physical exams might show no abnormalities other than high blood pressure. Signs of vascular damage, when present, correspond to the organs supplied by the affected vessels, leading to target organ damage. For...

Chronic Kidney Disease II: Clinical Manifestations

Chronic Kidney Disease (CKD) progressively impairs multiple body systems due to the accumulation of uremic toxins, which disrupt cellular functions across various organs.Neurologic symptomsNeurologic symptoms often arise early in CKD, as uremic toxin buildup drives changes in cognitive and motor functions. Patients frequently experience fatigue, headache, confusion, difficulty concentrating, and, in severe cases, seizures. Peripheral neuropathy commonly manifests as burning sensations in the...

Chronic Obstructive Pulmonary Disease IV: Clinical Manifestations

Chronic Obstructive Pulmonary Disease, or COPD, is a long-term condition marked by persistent and only partially reversible airflow limitation. It involves two overlapping conditions—chronic bronchitis and emphysema—which often co-appear but differ in dominant symptoms and underlying mechanisms.Chronic Bronchitis FeaturesChronic bronchitis presents with a persistent productive cough and thick, sometimes purulent mucus due to airway inflammation, enlarged mucus glands, and goblet cell...

Pulmonary Hypertension: Classification and Pathogenesis

Pulmonary hypertension (PH) is a severe health condition in which the mean pulmonary arterial pressure increases to 25 mmHg or more, even when the body is at rest. This high pressure in the blood vessels that transport blood from the heart to the lungs can cause various symptoms, including shortness of breath, can lead to right heart failure, and significantly affect the overall quality of life.
There are various classifications for PH, each relating to different underlying causes and also...
