History of stroke

Symptoms & Risk Factors

After a stroke, cardiovascular evaluation and ongoing management are critical because a meaningful share of strokes have a cardiac source — most commonly atrial fibrillation, but also valvular disease, structural heart abnormalities such as patent foramen ovale, and undiagnosed coronary disease. Recurrence risk is highest in the first year and remains elevated long term, but it can be reduced substantially with a carefully constructed prevention plan. The work centers on identifying the original mechanism when possible, addressing every modifiable risk factor aggressively, and choosing the right antithrombotic strategy based on what the workup reveals. Dr. Kedan partners closely with your neurologist so that the cardiac side of stroke prevention is fully addressed, with extended rhythm monitoring, echocardiography, and intensive risk-factor management working together.

What Cardiolucent Evaluates

  • Echocardiography with POCUS for cardiac sources of embolism, including bubble study when indicated
  • Extended ambulatory rhythm monitoring (2-week patch or longer) to detect occult atrial fibrillation
  • Carotid duplex ultrasound for cerebrovascular atherosclerosis
  • CHA2DS2-VASc and bleeding-risk scoring when AFib is identified
  • Advanced lipid panel with ApoB and Lp(a), with intensive LDL lowering
  • Blood pressure optimization with home and ambulatory monitoring
  • Diabetes and metabolic screening with HbA1c and insulin resistance markers
  • Coordination with neurology and, when appropriate, structural heart specialists for PFO closure

Recurrence Warning Symptoms

  • Sudden weakness or numbness on one side of the body — face, arm, or leg
  • Slurred speech or difficulty understanding language
  • Sudden vision changes, including loss of vision in one eye
  • Sudden loss of balance, coordination, or dizziness
  • Severe headache without obvious cause
  • Brief episodes of any of the above that resolve (TIA) are urgent warnings, not reassurance
  • Palpitations or irregular heartbeat that could indicate AFib
  • Any acute neurologic symptom is a 911 emergency, even if it resolves quickly

Risk Factors for Recurrence

  • Atrial fibrillation, including occult AFib detected only on extended monitoring
  • Suboptimal blood pressure control — the single most important modifiable factor
  • Persistent tobacco use after the index event
  • Uncontrolled diabetes and high LDL cholesterol
  • Untreated obstructive sleep apnea
  • Carotid or intracranial atherosclerosis
  • Patent foramen ovale (PFO) in select younger patients with cryptogenic stroke
  • Premature discontinuation of antithrombotic or statin therapy
  • Excess alcohol intake
  • Sedentary lifestyle and persistent obesity

How Cardiolucent Approaches Treatment

Dr. Kedan structures post-stroke cardiac care around two questions: what caused this stroke, and what will most reliably prevent the next one. If atrial fibrillation or a cardiac clot source is identified, full anticoagulation is typically recommended long term and selected based on kidney function, bleeding risk, and concurrent medications. Without an identified cardioembolic source, the plan generally combines antiplatelet therapy with intensive control of blood pressure, lipids, glucose, and tobacco. The concierge model supports the close, sustained follow-up that prevents medication slippage and catches new rhythm or imaging findings early, and Dr. Kedan coordinates seamlessly with your neurology team throughout.

Common Questions

Frequently Asked Questions

Why do I need a cardiologist after a stroke?
A significant share of strokes have a cardiac origin — most commonly atrial fibrillation, but also valve disease, structural heart abnormalities, and undetected coronary disease. A thorough cardiovascular evaluation is critical both to find the cause of the first stroke and to prevent the next one. Dr. Kedan partners with your neurologist to ensure that the cardiac side of stroke prevention is fully addressed.
What is the risk of having another stroke?
Recurrence risk is highest in the first year and remains elevated thereafter, but it falls substantially with appropriate prevention. The exact risk depends on the cause of the first stroke, the presence of atrial fibrillation, blood pressure control, lipid levels, and other vascular disease. Most patients can reduce their recurrence risk considerably with a structured plan.
What cardiac tests are typically done after a stroke?
Evaluation often includes echocardiography to look at heart structure and search for clot sources, extended rhythm monitoring to screen for atrial fibrillation, carotid ultrasound, and a full cardiovascular risk assessment. POCUS during office visits can add immediate insight. Dr. Kedan tailors the workup based on what is already known and what gaps remain.
Will I need to be on a blood thinner permanently?
If atrial fibrillation or a cardiac clot source is identified, full anticoagulation is usually recommended long term. Without those findings, most patients are managed with antiplatelet therapy, a statin, and aggressive blood pressure control instead. Dr. Kedan reviews the right strategy with you in detail so the rationale and trade-offs are clear.
How important is blood pressure control after a stroke?
It is arguably the single most important factor in preventing a second stroke. Even modest sustained reductions in blood pressure lower recurrence risk meaningfully. Home monitoring, regular review, and timely medication adjustments form the core of this part of the plan.
What lifestyle changes help reduce recurrence?
Stopping tobacco, controlling cholesterol and glucose, maintaining a healthy weight, regular aerobic exercise, treating sleep apnea, and limiting alcohol all reduce stroke risk significantly. Adherence to medications is equally important — most preventable second strokes occur when at least one component of the regimen has slipped. Dr. Kedan helps build a practical, sustainable plan rather than an overwhelming list.
How is rhythm monitoring used to find hidden atrial fibrillation?
Because AFib often comes and goes, a single EKG may miss it. Extended monitoring — using wearable patches or longer-term loop recorders — significantly increases detection in patients with otherwise unexplained stroke. Identifying AFib changes treatment from antiplatelet therapy to full anticoagulation, which is far more effective at preventing recurrence.
What symptoms should make me seek emergency care?
Sudden weakness or numbness on one side, slurred speech, vision changes, severe headache, loss of balance, or facial drooping should prompt an immediate 911 call, even if symptoms resolve quickly. A transient ischemic attack is often a warning before a larger stroke and deserves emergency evaluation. For non-emergent concerns, contact Cardiolucent at (310) 304-5555.
How often will I be seen after a stroke?
In the first six months, visits are typically every 1–3 months while medications are optimized and any rhythm or imaging findings are clarified. Once stable, follow-up moves to every 3–6 months. Schedule a consultation with Dr. Kedan to coordinate cardiac stroke-prevention care alongside your existing neurology follow-up.
