  2. Hypertrophy - Wikipedia

    en.wikipedia.org/wiki/Hypertrophy

    Hypertrophy is the increase in the volume of an organ or tissue due to the enlargement of its component cells. [1] It is distinguished from hyperplasia , in which the cells remain approximately the same size but increase in number. [ 2 ]

  3. Ventricular hypertrophy - Wikipedia

    en.wikipedia.org/wiki/Ventricular_hypertrophy

    Concentric hypertrophy results from various stressors to the heart including hypertension, congenital heart defects (such as Tetralogy of Fallot), valvular defects (aortic coarction or stenosis), and primary defects of the myocardium which directly cause hypertrophy (hypertrophic cardiomyopathy). The underlying commonality in these disease ...

  4. Cellular adaptation - Wikipedia

    en.wikipedia.org/wiki/Cellular_adaptation

    Cellular hypertrophy is an increase in cell size and volume. If enough cells of an organ hypertrophy the whole organ will increase in size. Hypertrophy may involve an increase in intracellular protein as well as cytosol (intracellular fluid) and other cytoplasmic components.

  5. Muscle hypertrophy - Wikipedia

    en.wikipedia.org/wiki/Muscle_hypertrophy

    As muscle hypertrophy is a response to strenuous anaerobic activity, ordinary everyday activity would become strenuous in diseases that result in premature muscle fatigue (neural or metabolic), or disrupt the excitation-contraction coupling in muscle, or cause repetitive or sustained involuntary muscle contractions (fasciculations, myotonia, or ...

  6. Hypertrophic cardiomyopathy - Wikipedia

    en.wikipedia.org/wiki/Hypertrophic_cardiomyopathy

    Ventricular hypertrophy causes a dynamic pressure gradient across the left ventricular outflow tract (LVOT), which is associated with further narrowing of the outflow during systole. Pulling of the mitral valve leaflets towards the septum contributes to the outflow obstruction.

  7. Haemodynamic response - Wikipedia

    en.wikipedia.org/wiki/Haemodynamic_response

    The increased workload on the heart causes hypertrophy of the right ventricle, which leads less blood being pump through the lungs and decreased blood to the left side of the heart. As a result of all of this, the left side of the heart has a hard time pumping a sufficient supply of oxygen to the rest of the body, which deteriorates the effect ...

    Some troops leave the battlefield injured. Others return from war with mental wounds. Yet many of the 2 million Iraq and Afghanistan veterans suffer from a condition the Defense Department refuses to acknowledge: Moral injury.

  9. Concentric hypertrophy - Wikipedia

    en.wikipedia.org/wiki/Concentric_hypertrophy

    Concentric hypertrophy is a hypertrophic growth of a hollow organ without overall enlargement, [1] in which the walls of the organ are thickened and its capacity or volume is diminished. Sarcomeres are added in parallel, as for example occurs in hypertrophic cardiomyopathy .
