01 · CLINICAL RATIONALE & FOCUS AREAS

Why endurance physiology after forty warrants a different clinical lens.

Habitual aerobic exercise is protective, yet high-volume and high-intensity training after age 40 intersects with evolving vascular biology, blood pressure reactivity, and systemic internal medicine considerations that routine checkups rarely address in athletic context.

DOMAIN 01 · VASCULAR & CARDIAC RISK

Cardiovascular & Cerebrovascular Risk Stratification

After age 40, occult atherosclerotic and neurovascular risk factors become the primary determinants of adverse exercise-related events. Even fit masters riders and runners can harbour silent hypertension, elevated lipoprotein(a), dyslipidemia, or a family history of premature vascular disease.

  • Individualized pre-training and pre-event cardiovascular risk profiling prior to stepping up training intensity or duration
  • Assessment of resting and exertional blood pressure responses (including masked or exercise-induced hypertension)
  • Lipid, apolipoprotein, and vascular risk interpretation tailored to active masters athletes
DOMAIN 02 · SYSTEMIC INTERNAL MEDICINE

Internal Medicine Aspects of Endurance Performance

Sustained aerobic output depends on integrated hematologic, metabolic, endocrine, and renal physiology. When a masters athlete experiences unexplained fatigue, blunted adaptation, or impaired recovery, a systematic internal medicine evaluation helps separate medical pathology from training load.

  • Hematologic and iron-store assessment (ferritin, transferrin saturation, hemoglobin indices, foot-strike or endurance hemolysis factors)
  • Metabolic, glycemic, and thyroid regulation in the context of high energy expenditure
  • Renal function, electrolyte homeostasis, and safe medication selection (e.g., antihypertensives that do not blunt exercise capacity)
  • Structured return-to-exertion medical evaluation following systemic or viral illness
DOMAIN 03 · SYMPTOM & DIAGNOSTIC EVALUATION

Evaluation of Exertional Symptoms & Telemetry Findings

Masters athletes closely monitor power meters, pace, and heart-rate straps—and are often the first to notice subtle physiological shifts. New symptoms or abnormal heart-rate patterns warrant objective clinical and diagnostic assessment rather than guesswork.

  • Workup of exertional dyspnea, atypical chest discomfort, presyncope, or unexplained drops in sustainable threshold
  • Evaluation of palpitations, ectopy, or heart-rate anomalies observed during or after rides and runs
  • Targeted ordering and clinical interpretation of Exercise Stress Testing (GXT), Echocardiography, and Ambulatory Holter Monitoring
  • Clear, evidence-based medical guidance on safe training boundaries while investigations are completed
APPROPRIATE OHIP REFERRAL INDICATIONS

When to consider a referral with your Family Physician

In accordance with the Ontario Health Insurance Plan (OHIP) Schedule of Benefits, specialist Internal Medicine consultations are provided for patients with a specific medical question or clinical indication identified by their primary care provider:

INDICATION A
Pre-Significant Training or Event Risk Evaluation (Age 40+)

Adults over 40 with one or more vascular or metabolic risk factors (hypertension, dyslipidemia, family history, prior smoking, or returning from a sedentary period) planning a substantial increase in endurance training or event participation.

INDICATION B
Exertional Symptoms or Unexplained Performance Decline

New or unexplained shortness of breath out of proportion to effort, chest tightness, palpitations, unexpected heart-rate surges/drops, dizziness, or persistent medical fatigue unresponsive to rest.

INDICATION C
Internal Medicine Optimization in the Active Patient

Management of hypertension, lipid abnormalities, iron deficiency, metabolic dysregulation, or neurovascular risk factors in an endurance athlete where medication choice and physiological load interact.

02 · CONSULTATIVE MANDATE & PRACTICE BOUNDARIES

A focused 1-to-2 visit Internal Medicine consultation.

Dr. Khosravani sees patients at Lawrence Park Cardiology on a dedicated, as-needed consultative basis. The pathway is intentionally structured as an episodic specialist assessment—typically one consultation, with a second follow-up visit when diagnostic tests are ordered—working in partnership with your Family Physician.

STEP 01 INTAKE & TRIAGE

Physician Referral to Lawrence Park Cardiology

Your Family Physician or Nurse Practitioner submits a referral via Ocean eReferral or clinic fax (647-347-6647) requesting an Internal Medicine consultation with Dr. Houman Khosravani. Include recent bloodwork or prior cardiac tests if available.

STEP 02 VISIT 1 · CONSULTATION

Comprehensive Internal Medicine Evaluation

A thorough clinical consultation reviewing your medical, vascular, and family history alongside your endurance training volume, intensity distribution, and symptoms—followed by a focused internal medicine physical examination and risk stratification.

STEP 03 WHEN INDICATED

Targeted On-Site Diagnostic Investigations

When clinically indicated, non-invasive cardiac testing (ECG, Exercise Stress Test, Resting or Stress Echocardiogram, Holter monitoring) is arranged directly at Lawrence Park Cardiology alongside targeted laboratory investigations.

STEP 04 VISIT 2 · FOLLOW-UP

Diagnostic Synthesis & Report to Primary Care

If diagnostic tests were ordered, a second focused consultation is scheduled to review your results, outline evidence-based medical guidance for safe training, and transmit a comprehensive consultation report back to your Family Physician.

REGULATORY & MEDICO-LEGAL CLARITY (CPSO & CMPA ALIGNED)

Clear boundaries of the consultation mandate

Clear expectations protect patient safety and continuity of care. Please review the scope of this episodic Internal Medicine consultation before requesting a referral:

WHAT THIS CONSULTATION PROVIDES
  • Episodic Specialist Evaluation (1–2 Visits): A focused Internal Medicine consultation addressing cardiovascular readiness, systemic physiology, and exertional symptoms in athletes 40+.
  • OHIP-Insured Medical Care: Billed strictly under the Ontario Schedule of Benefits for valid OHIP cardholders with a medically indicated physician/NP referral. Zero private membership or concierge fees.
  • Evidence-Based Diagnostic Workup: Clinical ordering and interpretation of accredited cardiac and laboratory testing when medically warranted by history, risk profile, or symptoms.
  • Continuity with Primary Care & Specialist Colleagues: Full written consultation note returned to your Family Physician, with seamless internal referral to Lawrence Park Cardiology Cardiologists or Internists if ongoing specialist management is needed.
WHAT THIS CONSULTATION IS NOT
  • Not Longitudinal Primary Care: Dr. Khosravani acts as a consulting specialist and does not assume ongoing primary care or routine prescription renewals unrelated to the consultation.
  • Not Commercial Athletic Coaching: While training load and physiology inform the clinical assessment, the consultation does not provide commercial coaching, daily workout programming, or sport-lab lactate/VO2max packages.
  • Not an Uninsured "Executive Health" Screening Package: Diagnostic tests are ordered strictly on clinical merit and medical indication in keeping with CPSO and OHIP standards.
