Cardiovascular Diseases Overview

• Prevalent serious disorders in industrialized nations, impacting overall health significantly.
• More common in men, but recent trends show increasing incidence in women.
• Absolute number of deaths from cardiovascular diseases has decreased in men, while it has increased for women due to factors such as obesity and Type 2 diabetes.

Factors Affecting Women

• Women experience more severe inflammation, obesity, and metabolic syndrome compared to men.
• Coronary artery disease (CAD) in women is often linked to dysfunction in the coronary microcirculation.

Diagnosis of Cardiovascular Disease

• Complete cardiac diagnosis requires a systematic assessment based on the New York Heart Association (NYHA) standards.

Diagnostic Elements

• Etiology: Determining the origin of the disease – congenital, hypertensive, ischemic, or inflammatory.
• Anatomic Abnormalities: Identifying which heart chambers are involved and their conditions (hypertrophied, dilated), the status of valves (regurgitant or stenotic), any pericardial involvement, and history of myocardial infarction.
• Physiologic Disturbances: Evaluating presence of arrhythmias, congestive heart failure, or myocardial ischemia.
• Functional Disability: Assessing the effort required to trigger symptoms during physical activity.

NYHA Functional Classification

• Class I: No physical activity limitation; no symptoms with normal exertion.
• Class II: Slight limitation of physical activity; ordinary activity causes symptoms.
• Class III: Marked limitation of physical activity; less than ordinary activity leads to symptoms, but asymptomatic at rest.
• Class IV: Inability to perform any physical activity without discomfort; symptoms present at rest.

Arterial Insufficiency and Neuromuscular Disorders

• Severe arterial insufficiency may present as muscular atrophy.
• Absence of hair growth along the affected extremity can indicate underlying issues.

Jugular Venous Pressure (JVP) and Waveform

• JVP is a critical bedside measurement for estimating patients' volume status.
• Internal jugular vein (IJV) is preferred for measurement due to its direct alignment with the superior vena cava and right atrium.
• External jugular vein is not suitable as it contains valves and is not directly in line with the heart structures.

Measurement Techniques

• Venous pressure is traditionally measured as the vertical distance from the top of the jugular venous pulsation to the sternal inflection point (angle of Louis).
• An abnormal JVP is indicated by a measurement greater than 4.5 cm when the patient is at a 30° elevation.

Considerations in Measurement

• The actual distance from the mid-right atrium to the angle of Louis can vary significantly based on body size, leading to potential inaccuracies.
• This variability may cause a systematic underestimation of central venous pressure (CVP).
• JVP is more effectively used to differentiate between normal and abnormally elevated CVP than for precise semi-quantification of volume status.

Jugular Venous Pressure & Waveform

• a wave: Represents right atrial presystolic contraction; occurs just after the P wave of the electrocardiogram and precedes the first heart sound (S1).
• Prominent α wave: Indicative of reduced right ventricular compliance.
• Cannon α wave: Associated with atrioventricular (AV) dissociation; not observed in atrial fibrillation.
• x descent: Indicates a decrease in right atrial pressure following the α wave inscription.
• c wave: Occurs when the closed tricuspid valve is pushed into the right atrium during early ventricular systole, interrupting the x descent and leading to a further descent.
• v wave: Represents atrial filling during diastole, occurring during ventricular systole; its height is influenced by right atrial compliance and blood volume returning to the right atrium (either from the cavae or retrograde through an incompetent tricuspid valve).
• Tricuspid Regurgitation (TR): In patients with TR, the v wave becomes accentuated, and the subsequent y descent occurs rapidly.
• y descent: Follows the peak of the v wave; may become prolonged or blunted in cases of right ventricular obstruction, such as stenosis or pericardial tamponade.

Jugular Venous Pressure (JVP)

• Normal venous pressure decreases by at least 3 mmHg upon inspiration.
• Kussmaul’s Sign indicates a rise or absence of fall in JVP with inspiration.
• Conditions associated with Kussmaul’s Sign include:
  • Constrictive pericarditis
  • Restrictive cardiomyopathy
  • Massive pulmonary embolism
  • Right ventricular infarction
  • Advanced left ventricular systolic heart failure
  • Isolated finding following cardiac surgery without other hemodynamic abnormalities.

Venous Hypertension

• Identified through passive leg elevation or the abdominojugular reflux maneuver.
• Abdominojugular Reflux requires firm pressure over the upper abdomen (especially right upper quadrant) for more than 15 seconds.
• A positive test results in a sustained JVP rise of more than 3 cm.
• Test results should be evaluated after 10 seconds of continuous pressure to minimize respiratory artifacts and muscle tension.

Interpretation of Findings

• A positive abdominojugular reflux indicates limited compliance in a volume-overloaded state due to an overly distended or restricted venous system.
• Pulmonary artery wedge pressure greater than 15 mmHg is common in heart failure patients.
• Elevated JVP signals increased risk for hospitalization related to heart failure and mortality from heart failure.

Blood Pressure Measurement Guidelines

• Measure blood pressure in a seated position with the arm at heart level, feet on the floor, and back supported.
• Allow 5-10 minutes for relaxation before measurement.
• In the supine position, raise the arm to the level of the mid-right atrium for accurate reading.

Cuff Inflation and Measurement

• Inflate the cuff to 30 mmHg above the expected systolic pressure.
• Release pressure at a rate of 2-3 mmHg per second to avoid inaccurate readings.
• Systolic pressure is identified by the first Korotkoff sound; diastolic pressure is identified by the fifth sound.

Cuff Sizing

• Cuff bladder length should be 80% and width 40% of the arm's circumference.
• Using too small a cuff leads to overestimation of blood pressure.
• Using too large a cuff results in underestimation of blood pressure.

Measurement Sites and Variations

• Blood pressure is best measured at the brachial artery level.
• Other potential measurement sites include the radial, popliteal, or pedal arteries.
• Expect systolic pressure to increase and diastolic pressure to decrease when taken in more distal arteries.

Bilateral Measurement

• Blood pressure should be measured in both arms.
• Note any differences between the readings for comprehensive assessment.

Jugular Venous Pressure Waves

• a wave (ascent): Caused by active contraction of the atrium, resulting in retrograde blood flow to neck veins.
• x wave (descent): Represents continued relaxation of the atrium post-contraction.
• c wave: Results from the pressure impact of the carotid artery, along with the backward transmission of a positive wave from the right ventricular systole and tricuspid valve bulging into the right atrium.
• x' wave (descent): Occurs as the tricuspid valve descends during ventricular systole, combined with continuous atrial relaxation.
• v wave (ascent): Associated with passive filling of the atrium due to venous return.
• y wave (descent): Triggered by the opening of the tricuspid valve, allowing rapid blood flow from the right atrium to right ventricle, leading to a decrease in right atrial pressure.

Jugular Venous Pressure Measurement

• Jugular venous pressure is determined by measuring the height of blood in the jugular vein above the right atrium.
• Standard measurement: 3 cm from the sternal angle plus an additional 5 cm to reach the right atrium, totaling 8 cm H2O for normal jugular venous pressure.

Jugular Venous Pulse Diagram

• Reflects pressure changes in the right atrium through a characteristic waveform consisting of multiple phases:
  • a wave: Indicates pressure surge due to atrial contraction.
  • c wave: Sharp peak correlating with tricuspid valve bulging into the right atrium during ventricular contraction.
  • x descent: Downward pressure deflection coinciding with right ventricular contraction and tricuspid valve movement.
  • v wave: Accumulates due to blood filling the right atrium from the venae cavae.
  • y descent: Results from the tricuspid valve opening, facilitating quick blood transfer to the right ventricle.

Phonocardiogram

• A tool for recording the sounds generated by the heart, valuable for clinical diagnosis.

Electrocardiogram (EKG)

• Monitors the heart's electrical activity, with key components:
  • P wave: Indicates depolarization of the atria.
  • QRS complex: Signifies depolarization of the ventricles.
  • T wave: Represents the repolarization of the ventricles.

Jugular Venous Pressure Measurement

• JVP is an important clinical measure used to assess right heart function and volume status.
• The patient is positioned supine (lying on their back) at a 45-degree angle to facilitate visibility of the jugular vein.
• A ruler is utilized to measure the height of the jugular vein above the sternal angle.
• In the described scenario, the jugular vein appears visibly engorged, indicated in blue on the right side of the neck.
• Maximum measurement indicated by the ruler is 10 cm, suggesting a potential abnormality in venous pressure.

Anatomy Involved

• The internal and external jugular veins are key structures for JVP measurement, both visible in the image.
• The sternocleidomastoid muscle serves as a landmark and reference point during the examination.
• Identifying the correct jugular vein and using the sternocleidomastoid muscle for orientation are crucial steps for accurate measurement.

Ankle-Brachial Index (ABI)

• ABI is calculated by measuring the systolic pressure in the dorsalis pedis and/or posterior tibial artery.
• The measurement is divided by the higher of the two brachial artery pressures for accurate comparison.
• Serves as a powerful predictor of long-term cardiovascular mortality.
• A low ABI indicates potential peripheral artery disease, increasing the risk of heart failure and stroke.
• Early detection through ABI measurement can lead to timely interventions and improved cardiovascular outcomes.

Ankle Brachial Index (ABI) Results

• ABI is a crucial measurement used to assess Peripheral Artery Disease (PAD) severity.
• Normal ABI values range from 1.0 to 1.3, indicating healthy blood flow.
• A measurement of ≥ 1.3 suggests abnormal calcification, which may indicate vascular issues.
• Borderline PAD is identified with ABI values between 0.9 and 0.99, indicating a potential risk for progression.
• Mild PAD is diagnosed with ABI values ranging from 0.7 to 0.89, signaling early signs of arterial obstruction.
• Moderate PAD is indicated by ABI values between 0.5 and 0.69, warranting closer monitoring and management.
• Severe PAD is present when ABI values fall below 0.5, which may lead to impending gangrene, necessitating urgent medical intervention.

Definition and Diagnosis

• White Coat Hypertension is characterized by elevated blood pressure readings during clinical visits but normal readings outside the clinic.
• Clinically defined as at least three clinic-based measurements greater than 130/80 mmHg.
• Requires at least two non-clinic blood pressure measurements showing a drop of 20 mmHg in systolic or more than 10 mmHg in diastolic pressure upon changing from supine to upright within 3 minutes.

Clinical Implications

• Absence of compensatory tachycardia indicates potential autonomic insufficiency, important in conditions like diabetes mellitus or Parkinson’s disease.
• Can lead to postural lightheadedness or syncope, necessitating routine assessment in patients.

Risk Factors

• Advanced age increases susceptibility to White Coat Hypertension.
• Dehydration, specific medications, food intake, decreased physical conditioning, and environmental factors such as temperature and humidity can exacerbate the condition.

Arterial Pulse Overview

• Carotid artery pulse follows the ascending pulse from the aorta.
• Aortic pulse is most effectively felt in the epigastric area, situated just above the umbilicus.

  • Symmetry
  • Volume
  • Timing
  • Contour
  • Amplitude
  • Duration

Notable Observations

• Up to 10% of normal individuals may not have palpable pulses in one foot; assessments should be done systematically on both sides.
• Allen's Test is utilized to check the integrity of the hand's arcuate system, typically before procedures involving the radial artery.

Arterial Pulse Assessment

• Carotid Artery Pulse: Occurs just after the ascending aortic pulse.
• Aortic Pulse: Best felt in the epigastrium, located just above the umbilicus.
• Peripheral Pulses to Assess: Include subclavian, brachial, ulnar, femoral, popliteal, dorsalis pedis, and posterior tibial.
• Examining Pulses: Focus on symmetry, volume, timing, contour, amplitude, and duration.
• Pedal Pulses: Up to 10% of normal subjects may not have one palpable pedal pulse; assess both systematically.

Allen's Test

• Purpose: Evaluates the integrity of the hand's arterial supply (radial and ulnar arteries).
• Procedure:
  • Place thumbs over the radial and ulnar arteries.
  • Instruct the patient to clench their hand three times quickly.
  • Compress the arteries and ask the patient to extend their fingers; the hand should blanch.
• Interpreting Results:
  • Release the radial artery and observe skin color return; a delay of over 3 seconds indicates potential issues.
  • Repeat with the ulnar artery to further assess vascular patency.

• Rare occurrence, primarily noted in patients with severe aortic regurgitation.

Bisferiens Pulse in Hypertrophic Obstructive Cardiomyopathy

• Features a rapid upstroke leading to the first peak (known as a percussion wave).
• Followed by a slower rise to the second peak (referred to as a tidal wave).

Dicrotic Pulse

• Shows peaks occurring in both systole and diastole.
• Often observed in conditions such as sepsis or during intraaortic balloon counterpulsation, particularly just after the dicrotic notch.

Additional Notes

• These characteristics help in diagnosing various cardiac conditions.

Pulsus Parvus et Tardus

• Characterized by a weak and delayed pulse.
• Commonly observed in severe aortic stenosis (AS).
• May present with a slow, notched, or interrupted upstroke, known as anacrotic pulse.
• Can be associated with a thrill or shudder during palpation.

Bifid or Bisferiens Pulse

• Features two systolic peaks, indicative of advanced aortic regurgitation (AR).
• In chronic severe AR, the carotid upstroke exhibits a sharp rise followed by a rapid decline, termed Corrigan's or Water-Hammer Pulse.
• This pulse type is also seen in hypertrophic obstructive cardiomyopathy (HOCM).

Diagrams Overview

• Four diagrams illustrate different pulse types:
  • Diagram A and B: Both show pulsus parvus et tardus, featuring a small, slow upstroke and a dicrotic notch.
  • Diagram C and D: Illustrate a bifid or bisferiens pulse with two distinct systolic peaks and a dicrotic notch.

Pulsus Paradoxus Overview

• Defined as a fall in systolic blood pressure greater than 10 mmHg during inspiration.
• Occurs due to exaggerated interventricular dependence, impacting heart function across the respiratory cycle.
• Commonly observed in conditions such as pericardial tamponade, massive pulmonary embolism, hemorrhagic shock, severe obstructive lung disease, and tension pneumothorax.

Pulsus Paradoxus Mechanism

• During inspiration, increased venous return to the right heart causes the septum to shift left, leading to reduced filling in the left ventricle and decreased stroke volume.
• During expiration, the septum shifts right, resulting in an increase in stroke volume.
• The changes in stroke volume directly affect blood pressure readings throughout the respiratory cycle.

Blood Pressure Variability

• Normal blood pressure variation during the respiratory cycle ranges from 0-10 mmHg.
• In pulsus paradoxus, the blood pressure variation exceeds 10 mmHg, indicating significant respiratory impact on cardiac function.
• Visual representations typically use a solid line for normal blood pressure and a dashed line to illustrate pulsus paradoxus trends.

Pulsus Alternans

• Characterized by beat-to-beat variability in pulse amplitude.
• Commonly observed in severe left ventricular (LV) systolic dysfunction.
• Caused by cyclic fluctuations in intracellular calcium levels and variations in action potential duration.
• When associated with electrocardiographic T-wave alternans, it significantly increases the risk of arrhythmias.

Peripheral Arterial Disease (PAD)

• Physical examination can often reveal the level of arterial obstruction causing claudication.
• Symptoms typically include claudication (pain with exercise), coolness of the skin, abnormal findings on pulse examinations, and the presence of a vascular bruit (abnormal sound in blood vessels).
• Abnormal pulse oximetry, defined as a difference greater than 2% between finger and toe oxygen saturation, is a useful method for detecting lower extremity PAD.
• The pulse oximetry method is comparable to the ankle-brachial index in assessing PAD severity.

Inspection of the Heart

• Apex beat may be visible in the midclavicular line at the fifth intercostal space in thin-chested adults.
• Anterior chest wall heaving indicates enlarged or hyperdynamic left or right ventricle.
• Visible right upper parasternal pulsation can suggest ascending aortic aneurysm disease.

Palpation of the Heart

• Left ventricular (LV) cavity enlargement manifests as a leftward and downward displacement of the apex beat.
• A sustained apex beat signals pressure overload due to aortic stenosis (AS) or chronic hypertension.
• Palpable presystolic impulse corresponds to fourth heart sound (S4), indicating reduced LV compliance and forceful atrial contraction.
• Palpable third sound (S3) indicates rapid early filling in heart failure; may be present even if gallop sound is inaudible.
• Right ventricular pressure or volume overload may result in a sternal lift.
• Confirmatory signs of tricuspid regurgitation (TR) include CV waves in the jugular venous pulse; pulmonary arterial hypertension may present as a loud single or palpable P2.

Auscultation of the Heart

• First Heart Sound (S1): Closure of mitral and tricuspid valves.
• Second Heart Sound (S2): Closure of aortic (A2) and pulmonic (P2) valves; normal splitting occurs with inspiration and narrows with expiration.
• Third Heart Sound (S3): Occurs during rapid ventricular filling; normal in children and young adults but signifies heart failure in older patients. Left-sided S3 is low-pitched, best heard over LV apex, and predictive of cardiovascular morbidity and mortality; prevalent in heart failure with preserved and reduced LV ejection fraction.
• Fourth Heart Sound (S4): Occurs during atrial filling phase, indicating LV presystolic expansion; common in patients benefiting from atrial contribution to filling, such as those with chronic LV hypertrophy or active myocardial ischemia. S4 is absent in atrial fibrillation.

• ST segment levels are measured at this J point.
• Upper limits of normal J point elevation:
  • 0.2 mV for men aged 40 or older.
  • 0.25 mV for men younger than 40.
  • 0.15 mV for women.
• Recommended upper limit for J point elevation in other leads is 0.1 mV for both men and women.

QT Interval

• Normal QT interval is affected by heart rate; it decreases as the heart rate increases.
• The longest QT interval is typically measured from leads V2 and V3.
• AHA and ACC recommend an upper limit for QTc:

J Wave and J Point

• J wave: The onset of the ST-T wave at the J point, typically located at or near the isoelectric baseline of the ECG.
• ST segment level is measured at the J point.

QT Interval

• Normal QT interval is heart rate dependent; it decreases as heart rate increases.
• When measuring the QT interval from multiple leads, it is determined from the lead where the interval is longest, usually lead V2 and V3.

Ischemia and ECG Findings

• The earliest and most consistent ECG finding in ischemia is ST segment deviation.
• This deviation results from complex injury mechanisms affecting cardiac tissue.
• In cases of predominant subendocardial ischemia, the ST vector points toward the inner layer of the ventricle and the ventricular cavity.

• This examination can reveal changes in blood vessels associated with systemic diseases, aiding in early detection.
• Arcus senilis, a gray or white arc around the cornea, is commonly observed with aging but shows low specificity for coronary heart disease risk.
• While the presence of arcus senilis may indicate lipid abnormalities, it should not be used alone to assess cardiovascular risk.

Physical Examination of the Chest
