14 Possible Causes for Impaired Exercise Tolerance, Increased Area of Cardiac Dullness, Sudden Death

  • Congestive Heart Failure

    The basic pharmacology of PDE inhibitors is presented and the use of PDE-3 inhibitors for the treatment of heart failure causing an increase in sudden death is also reviewed[] The impairment of exercise tolerance indicated by NYHA classification was markedly improved by PD for both groups.[] Numerous mechanisms unrelated to hemodynamic dysfunction may underlie impaired exercise tolerance in patients with chronic heart failure.[]

  • Cardiomyopathy

    A thorough family history of juvenile sudden death, ventricular arrhythmias and ICD implants should always be sought.[] METHODS: Two cases of sudden cardiac death owing to ARVC were reported.[] Sudden Death Risk A major impetus in HCM has been the identification of those patients at increased risk for sudden death.[]

  • Aortic Valve Stenosis

    death. 1,4–6 Several studies have attempted to ascertain the risk of sudden death in the population of asymptomatic patients with severe aortic stenosis.[] The occurrence of AS-related events (sudden death, congestive heart failure or new onset of symptoms) within two years was recorded prospectively.[] death without previous cardiac decompensation.[]

  • Dilated Cardiomyopathy

    The patient presented with sudden arrhythmic death and survived with permanent anoxic brain injury.[] In the family, there was a strong family history of DCM and sudden cardiac death in four generations.[] death.[]

  • Ischemic Cardiomyopathy

    KEYWORDS: Cardiac magnetic resonance; Non-ischemic cardiomyopathy; Sudden cardiac death[] The cardinal manifestations of HF are dyspnea and fatigue, which may limit exercise tolerance, and fluid retention, which may lead to pulmonary congestion and peripheral edema[] Beta-blockers may avert sudden death in heart failure.[]

  • Primary Cardiomyopathy

    death, Cardiomegaly Functional AV valve regurgitation S3 and/or S4 Exertional dyspnea, angina, syncope, sudden death Systolic murmur mitral regurgitation murmur, S4 Bifid[] Clinically overt hypertrophic cardiomyopathy is the most common cause of sudden unexpected death in childhood.[] Arrhythmias represent the major cause of death in these patients causing sudden death.[]

  • Alcoholic Cardiomyopathy

    The frequency of alcoholic cardiomyopathy among victims of sudden death suggests that alcoholic cardiomyopathy is a risk factor for sudden cardiac death.[] Abstract The morphologic features of alcoholic cardiomyopathy in human sudden death compared with those of experimental alcoholic cardiomyopathy (6 weeks of alcohol administration[] Abstract Seven hundred fifty-two cases of instantaneous sudden cardiac death were studied.[]

  • Heart Disease

    Manifestations range from subclinical to sudden death (death, sudden).[] The first symptom of undiagnosed coronary disease is sudden death in almost one-third of patients with the disease.[] The latter, characterized by an uncontrolled and uncoordinated contraction of the ventricles (the lower chambers of the heart), can induce sudden death.[]

  • Peripartum Cardiomyopathy

    Sudden deaths during the course of PPCM are reported to be elevated, the underlying mechanisms remains unknown.[] Aggressive use of implantable defibrillators has significantly reduced the risk of sudden death in these patients.[] KEYWORDS: Peripartum cardiomyopathy; Sudden cardiac death; Ventricular tachyarrhythmia; Wearable cardioverter/defibrillator[]

  • Toxic Myocarditis

    Kussmaul's sign A paradoxical increase in venous distention and pressure during inspiration. Finding associated with cardiac tamponade.[] Although sudden unexpected death in children and young people has been scarcely studied, a significant proportion (16%) of all sudden deaths and a considerable percentage[] There have been sudden deaths associated with exceptional physical exertion in patients with viral illnesses.[]
