Select the/all correct statements about eccentric ventricular hypertrophy.Group of answer choicesIt may result in severely compromised ventricular filling.It may result in a decreased ability of the heart to respond to adrenergic stimulation.It is the consequence of pressure overload.It is characterised by featuring elongated but thin cardiomyocytes.

1 ptsAstronaut on the International Space Station (ISS) follow strict training and exercise regimes. Despite these training regimes, there is still noticeable change in the heart with a reduction in Heart Mass, including left ventricular mass, and enlarged left atrium. Which of the following are plausible contributing factors, and/or explanation for the observed changes in cardiac morphology?(select all that are correct, even if it is only one answer)Each correct answer will score partial points, each incorrect answer will score an equivalent deductionGroup of answer choicesThe lack of gravity directly affects cardiac myocytes resulting in atrophyThe lack of exercise results in less cardiac work loadThe observed reduction in systemic vascular resistance = lower afterloadThe lack of gravitational effect results in a lower afterload on the heart

A 45-year-old woman presented with exertional dyspnea. Fourteen years earlier the patient was diagnosed with arterial hypertension with a blood pressure of 170/105 mm Hg. Her blood pressure at presentation was 155/95 mm Hg. Physical examination was remarkable for lower-extremity edema, and abdominal enlargement due to ascites. Transthoracic echocardiogram showed left ventricular ejection fraction of 28% (reference range: 50-57%). Which of the following is the patterns of cardiac failure seen in this patient?

Explain why the narrowing of arteries can cause a heart attack?
