Insights

Stroke causes in the growing Black Caribbean population in the US are understudied. In Haitian-born patients, small vessel occlusion was the most common stroke subtype, often linked to hypertension.

Area of Science:

  • Neurology
  • Public Health
  • Epidemiology

Background:

  • The Black Caribbean population in the US is expanding.
  • Limited understanding exists regarding stroke causes within this demographic.
  • Haitian-born individuals represent a significant portion of the Black Caribbean community.

Purpose of the Study:

  • To investigate the stroke subtypes and their associated risk factors in Haitian-born patients admitted for acute stroke in Miami.
  • To identify prevalent etiologies of stroke in this specific ethnic group.

Main Methods:

  • Retrospective analysis of 175 consecutive Haitian-born patients admitted for acute stroke.
  • Classification of stroke subtypes (ischemic, hemorrhagic).
  • Assessment of cardiovascular risk factors, including hypertension, medication noncompliance, and intracranial atherosclerosis.

Main Results:

  • Ischemic stroke accounted for 72% of cases.
  • Small vessel occlusion was the most frequent stroke subtype identified.
  • High prevalence of hypertension, medication noncompliance, and intracranial atherosclerosis was observed.
  • Hypertension was the sole cardiovascular risk factor significantly associated with small vessel infarction.

Conclusions:

  • Small vessel occlusion is a predominant stroke subtype among Haitian-born individuals in Miami.
  • Hypertension is a key modifiable risk factor for small vessel infarction in this population.
  • Further research is warranted to understand and mitigate stroke burden in the Black Caribbean community.

American Trypanosomiasis

Chagas disease, or American trypanosomiasis, is a vector-borne parasitic infection caused by Trypanosoma cruzi, a flagellated protozoan (kinetoplastid) of the family Trypanosomatidae. The disease is endemic in Latin America, although cases are increasingly reported worldwide due to human migration. Transmission most commonly occurs when feces of infected triatomine bugs contaminate bite wounds or mucosal surfaces; additional routes include congenital, transfusional, transplant-related, and oral...
Stroke: Introduction and Types01:29

Stroke: Introduction and Types

A stroke is an acute neurological event caused by the sudden disruption of cerebral blood flow, leading to rapid loss of neuronal function. Neurons depend on continuous oxygen and glucose supply, so even brief interruptions can cause irreversible injury within minutes. Strokes are classified into ischemic and hemorrhagic types.Ischemic StrokeIschemic strokes are most common and occur due to arterial occlusion, depriving brain tissue of oxygen and nutrients. This leads to energy failure, ionic...
Ischemic Stroke l: Introduction01:15

Ischemic Stroke l: Introduction

Ischemic stroke is an acute cerebrovascular condition in which blood flow to a brain region is suddenly interrupted, leading to tissue infarction. Neurons depend on continuous oxygen and glucose supply, so even brief reductions in perfusion cause energy failure, ionic imbalance, and irreversible injury. Ischemic strokes are classified into thrombotic and embolic types based on their underlying mechanisms.Thrombotic MechanismsThrombotic stroke develops when a clot forms within a cerebral artery.
Ischemic Stroke ll: Pathophysiology01:15

Ischemic Stroke ll: Pathophysiology

An ischemic stroke occurs when a cerebral blood vessel becomes obstructed, most often by a thrombus or embolus, interrupting the delivery of oxygen and glucose to brain tissue. Because neurons rely on continuous aerobic metabolism, energy failure begins within minutes of reduced perfusion. The region receiving the least blood flow becomes the infarct core, an area of irreversible cellular death. Surrounding this core lies the penumbra, a zone of hypoperfused but still viable tissue that is...
Hemorrhagic Stroke l: Introduction01:17

Hemorrhagic Stroke l: Introduction

A hemorrhagic stroke is an acute neurological event that occurs when a weakened cerebral blood vessel ruptures, allowing blood to accumulate within or around the brain. The sudden release of blood forms a focal hematoma that increases intracranial pressure, displaces neural tissue, and can obstruct cerebrospinal fluid pathways. These effects may be compounded by intraventricular extension of the hemorrhage, cerebral edema, or compression of adjacent structures, all of which contribute to...
Hemorrhagic Stroke ll: Pathophysiology01:29

Hemorrhagic Stroke ll: Pathophysiology

A hemorrhagic stroke develops when a cerebral blood vessel ruptures, allowing blood to escape into the surrounding brain tissue, as in intracerebral hemorrhage (ICH), or into the subarachnoid space, as in subarachnoid hemorrhage (SAH). Because the skull is a rigid compartment, the sudden presence of extravascular blood rapidly increases intracranial pressure and compresses adjacent neural structures, leading to immediate tissue injury and impaired cerebral perfusion.Mass Effect and Primary...
